VALVES & MEASUREMENT Little Rock. crude oil and refined products transmission lines. gathering lines and transmission systems to refineries. AR Cameron’s Valves & Measurement (V&M) group is a leading provider of valves and measurement systems to the oil and gas industry. The Engineered & Process Valves division provides a wide range of valves for use in natural gas. petrochemical plants and industrial centers for processing. LNG. direct and measure the flow of oil and gas as it is moved from individual wellheads through flow lines. These brands are complimented by WKM® and TBV™ valve products and considerably expand the scope of this division’s product offerings. aviation fueling. Cameron is the world’s leading manufacturer of high-integrity. RING-O®. ENTECH™ and TK® product lines. 4 GENERAL VALVE® CT-GEN-TWINSEAL-03 09/11-SWP-3M . TOM WHEATLEY®. The division also provides critical service valves for refinery. The traditional CAMERON® fully-welded ball valve product line has been combined with the GROVE®. positive Shut-off Double Block & Bleed valves which serve the pipeline. chemical and petrochemical processing businesses and for associated storage terminal applications. This broad offering has significantly strengthened Cameron’s ability to serve as a single source for a wide scope of customer requirements. particularly through the ORBIT® and GENERAL VALVE®. The group’s products are primarily used to control. refining. oil / gas production and custody transfer for the petroleum and oil and gas industries. liquid bulk terminals. pride in manufacturing workmanship and the selection of the best materials. The body (serving as a spool piece) bleed verifies seal integrity. The age-old double block & bleed system (as shown above) required the use of two valves and a spool piece. reduces maintenance and saves money. Any TWIN SEAL’S totally retracted slip design eliminates wear. foreign material lodged between the seats and ball or gate will score the seating surfaces. The TWIN SEAL avoids abrasion by having both independent slips totally retracted from the body bore during cycling..more than 68 years ago. CT-GEN-TWINSEAL-03 09/11-SWP-3M GENERAL VALVE® 5 . were the first to meet the rigid requirements of double block & bleed service .. A bleed valve was used to drain the spool and verify seal integrity. In the years since. Scored seating segments Seal abrasion is inherent in the design of most ball and gate valves.VALVES & MEASUREMENT GENERAL VALVE® Twin Seal™ THE EVOLUTION OF DOUBLE BLOCK & BLEED CONTINUES. In most instances. support Cameron’s commitment to excellence and complete customer satisfaction. subtle yet significant design refinements have been made to improve the valve’s performance. the seats are ground or wedged against metal every time the valve cycles. Superior design innovations. minimizes leakage risk. The TWIN SEAL replaces this antiquated two-valve system with just one double seated bubble-tight valve. The upstream and downstream seals provide the same function as the two block valves. product loss and contamination results. TWIN SEAL™ valves. Once the seating segment is scored. Introduced in 1941. 6 GENERAL VALVE® CT-GEN-TWINSEAL-03 09/11-SWP-3M . The ball valve may be leaking until the user opens the bleed. TWIN SEAL valves. it leaks. double block & bleed valve was developed for multi-products fuel manifolds. often with power actuators and sometimes without supervision. diesel. every time. gasoline. kerosene. In contrast. zero-leakage. heating oil and LPG as well as crude oil and natural gas are protected from contamination. The user can form a false impression that the ball valve is holding tight. Contamination is avoided in multi-products manifolds. Busy manifolds must be operated frequently. Even a small leak will cause errors in the meter calibration. to seal drop-tight. every closed valve in the meter system must seal drop tight. will prevent the expensive consequences of contaminated fuel. the seals typically rely on springs to press them against the ball. Then the reduction of the body pressure introduces a hydraulic force on the seat that may stop the leak. Liquid fuels that move through pipeline manifolds are reliably segregated by provable. TWIN SEAL valves hold with consistent zero-leakage. needing no help from the line pressure. the mechanical wedge-action of the TWIN SEAL plug compresses both the upstream and the downstream seals firmly against the valve body. switching from product to product. the differential pressure across each closed valve is very low. By using TWIN SEAL valves. During meter calibration (proving). Valves that can be trusted Meter Stations Flow meters require calibration to verify their accuracy. There is no assistance required from the line pressure to “energize” or compress floating seals to make them hold tight. That means correct calibration every time. when in reality. Multi-Product Manifolds The TWIN SEAL positive shut-off. Every TWIN SEAL valve in the manifold has assured double block and bleed shut-off that proves total isolation of each product. The incorrect meter factor will persist until the next proving operation and incorrect flow measurement can cost huge sums of money! Every TWIN SEAL valve in the meter station can be quickly and easily shown to be holding leak-tight. Unless the body cavity in a ball valve is vented.VALVES & MEASUREMENT GENERAL VALVE® Twin Seal™ THE PROVABLE ZERO-LEAKAGE DOUBLE BLOCK & BLEED PLUG VALVE WITH RETRACTING SEALS TWIN SEAL Advantages In meter block service. jet fuel. TWIN SEAL valves are the recognized Hydrant Valves for airport service because: • • • • They close quickly and easily They require very little maintenance They hold with zero-leakage They hold a verifiable bubble tight seal The hydrant pressure-test can begin as soon as the valves are closed. since the TWIN SEAL valves ensure that the hydrant is isolated.VALVES & MEASUREMENT GENERAL VALVE® Twin Seal™ THE PROVABLE ZERO-LEAKAGE DOUBLE BLOCK & BLEED PLUG VALVE WITH RETRACTING SEALS Tank Storage Isolation Fuel in storage tanks is exposed to the risk of contamination and loss of volume unless the tank isolation valves can be checked for zero leakage. but assuring tank integrity without TWIN SEAL can be troublesome and expensive. There is an assurance of valve integrity. Using line blinds (or skillet plates) for segregation involves a long. Generally speaking airports don’t have the time to drain fuel from the lines or to swing line blinds for traditional line block. costly and perhaps hazardous operation of drain-down. On some occasions. Loading / Unloading Fuel loading / unloading may require hundreds of open / close strokes of the connection valves every day. from Sidney to Sicily. truck and ship load manifolds. yet the valves must operate quickly and easily. CT-GEN-TWINSEAL-03 09/11-SWP-3M GENERAL VALVE® 7 . provable. it may become necessary to isolate section by section to find the location of a leak. Or. But the only time this inspection can be performed is in the few hours each night when the airport is closed. TWIN SEAL valves have two resilient seals that fully retract from their seated position without any seal rubbing even at full differential pressure. fuel movement managers have discovered TWIN SEAL valves are the valves they can trust to deliver real dependability at their loading manifolds. flanges and gaskets. From Alaska to Argentina. tank-side isolation. but the entire hydrant must be isolated and pressurized to prove that it is safe. from New York to New Zealand. TWIN SEAL valves offer simple. Plug turning is effortless and slam-proof! Fuel Loading Hazards are Eliminated Countless loading facilities depend on TWIN SEAL valves for safe. Hydrant Isolation Fuel hydrants at busy airports must be regularly pressure tested to check the integrity of the pipes. The valves typically operate against full pump pressure on every stroke. Traditional gate valve double block & bleed may produce loss of fuel from the open bleed. lock-out and tag-out. sections of the hydrant must be isolated for extension. reliable. Safety and environmental concerns demand that the fuel is absolutely and totally contained within the pipe. zero-leakage shut-off at rail. and they must close without leakage. modification or repair. Tank side valves are operated frequently. By simply removing the valve bonnet or lower plate (after the line is depressurized and drained). in-line field maintenance keeps costs down A big advantage of TWIN SEAL’S design is that it permits “in-line” servicing. 8 GENERAL VALVE® CT-GEN-TWINSEAL-03 09/11-SWP-3M .  In the closed position. Cameron offers a Slip Exchange Program. During rotation. It even seals in vacuum service. the valve requires less torque to cycle. B A 2. Because the seals never drag in well maintained valves. line contents drained from the valve and the line and the body cavity! Failure to follow these instructions could result in injury to personnel. For complete instructions on installation and repair. Seals (A) are permanently bonded into the slips (B) which are mounted on a central plug.  Turning the operator handwheel clockwise rotates the plug assembly 90° to block flow.  When the operator is turned further clockwise. the TWIN SEAL doesn’t rely on line pressure differential to help make its seal. forcing the slips against the body initiating the verifiable seal. allowing free movement and avoiding abrasion. 4. In the open position the slip seals are completely out of the flow. or cause hazardous product to be vented from the valve. request a copy of TWIN SEAL Installation Manual from your local Cameron Sales Office. Simple. the slip seals are expanded.VALVES & MEASUREMENT GENERAL VALVE® Twin Seal™ HOW THE TWIN SEAL WORKS 1. Because it is mechanical.  The internal design is very simple. WARNING: Do not attempt any repairs on TWIN SEAL valves unless you are certain the line pressure has been removed and the 3. compressing the slip seals until metal-to-metal seating is effected. the tapered plug begins to lower. clearance is maintained between the seal and the valve body. all models may be repaired from top or bottom without removing the valve from the line.

Easy. Most underground valves are difficult to maintain and service. however. B. Slip replacement is quick and easy. Once the slips have been replaced. The hydraulic extension for gear operators is essentially a hydrostatic transmission. there are virtually no limitations on length and orientation.VALVES & MEASUREMENT GENERAL VALVE® Twin Seal™ DIRECT BURIAl – UNDERGROUND Patented TWIN SEAL extended bonnet valves greatly simplify maintenance in underground applications while providing dependable double block and bleed shut-off. Since the self-contained hydraulic extension systems are manually-hydraulically operated. the designer has the freedom to put the valves in their ideal locations. There is no limitation on the number of corners turned between the valve and handwheel. System designers often must compromise valve placement to overcome this maintenance problem. Installation costs are minimized. This approach allows the system designer maximum flexibility since the only connections between the handwheel and valve are hydraulic tubes. Dual above-grade handwheel pump assemblies are mounted on the same pedestal. Hydraulic Extension System Installation Typical hydraulic extension system installation with two valves. Inexpensive Maintenance Once extended bonnet valves have been installed. TWIN SEAL hydraulic extension systems are available for installations where standard Type A. Unbolting and lifting the bonnet raises the valve plug and slips to ground level. Seal effectiveness can be immediately evaluated. An isolation valve installed in the upstream throat tap is also included in this system. also integrally mounted in the upper relief / vent manifold. routes excess pressure to the upstream throat of the valve. This system functions only when the valve is closed. The differential thermal relief system is arranged as shown. This bleed valve must be closed before the TWIN SEAL is reopened. heavy wall pipe and incident control. Manual Bleed (MBBV) Safety Bleed / DTR (Standard) Safety Block / DTR A manual body bleed valve is included on this TWIN SEAL. When the TWIN SEAL valve is seated and completely filled with liquid. CT-GEN-TWINSEAL-03 09/11-SWP-3M GENERAL VALVE® 21 . The safety block / DTR functions exactly the same as the basic safety bleed. It must be left open to permit the relief system to relieve pressure upstream. all working components are housed in a virtually indestructible compact carbon steel manifold. a pressure relief device must be provided on all double block and bleed valves in liquid service. The integral relief valve. The benefits of this incident control equipment are: fire safety. all socket welded joints. therefore all TWIN SEAL valves in liquid service must always be installed with a pressure relief device.VALVES & MEASUREMENT GENERAL VALVE® Twin Seal™ PRESSURE RELIEF SYSTEMS To satisfy the requirements of API 6D. A manual body bleed. even a slight increase in temperature due to the sun’s rays will result in a significant increases in the body cavity pressure resulting from thermal expansion. However. is opened only to vent and to verify seal integrity. mounted in the upper relief/vent manifold. This bleed valve installed in the body cavity is only opened after the TWIN SEAL is closed. complete component access for maintenance purposes. The standard relief valve is set to open at 25 psi above upstream pressure. the bleed valve is automatically closed by the combination of line pressure and the spring in the bleed valve. A relief valve (25 psid standard) is connected to the downstream throat tap via the lower tee. When the TWIN SEAL is seated and the downstream piping is sealed bubble-tight. An additional isolation valve is installed downstream for maintenance purpose. it pressure protects the downstream piping. When the TWIN SEAL is opened. Seal integrity is indicated by viewing the discharge of the bleed valve. positive assurance that the TWIN SEAL has sealed completely at each cycling operation and prevents thermal pressure buildups in the body cavity. the piping faces thermal over pressurization. An automatic bleed valve connected to the body cavity of the main valve is mechanically opened by the valve operator when the TWIN SEAL is seated.VALVES & MEASUREMENT GENERAL VALVE® Twin Seal™ PRESSURE RELIEF SYSTEMS The Automatic Body Bleed Valve (ABBV) provides visual.
