M2582, M5081, and M5180 Series Electromechanical and Pneumatic, Fuel Gas Shutoff Valves Installation and OperationInstructions GENERAL INFORMATION M-7980N Revised 11-02 Section 55 (00-02-0206) Please read the following instructions before installing. A visual inspection of this product for damage during shipping is recommended before mounting. It is your responsibility to have a qualified person install the unit and make sure installation conforms with NEC and local codes. WARNING BEFORE BEGINNING INSTALLATION OF THIS MURPHY PRODUCT ✔ ✔ ✔ ✔ Disconnect all electrical power to the machine. Make sure the machine cannot operate during installation. Follow all safety warnings of the machine manufacturer. Read and follow all installation instructions. Model M5081 Approved* M2582 and M5081Series Tripping Power From Engine Ignition System or Battery (Models available for magneto, CD ignition or 12/24 V battery) These fuel shut-off valves are semi-automatic devices for shutdown of natural gas fueled engines. The standard valve opens by manual operation of the reset handle. A latch in the upper body of the valve will set and hold the valve open. At this point no electric power is used. The electromagnetic coil is de-energized, the snap-switch(es) is SET. If a SWICHGAGE® contact closes, a circuit is completed from power through the snap-switch and coil. Now energized, the electromagnet trips the latch, (latch can be tripped manually), the valve closes, and the snap-switch resets. Power switches from the coil circuit to your choice of an open line, an electrical ground, or an alarm. After tripping, the vent seal opens, and on the M50 models, the open/close indicator (green button) retracts to indicate that the valve is closed. Valve body is sandcast aluminum. Optional cast steel for M5081 models. M2582-P and M5180-P MURPHY-NUMATIC™ Pneumatic Version for Pressure The M2582-P and M5180 pneumatically controlled valves can operate from pressure, and are designed to open and close automatically or semiautomatically (the supply can be air, oil or gas). NOTE: If using oil as a pressure source, use a lightweight oil. These valves will open on rising control pressure and close on decreasing control pressure. M2582-P and M5180-P automatically open at 2 psi (14 kPa) [0.14 bar] and fully open at 3 psi (21 kPa) [0.21 bar]. All models include a built-in lever to aid in opening the valve manually. The M2582-P can be manually opened against inlet pressure of 80 psi (552 kPa) [5.52 bar]. The M5180-P valve can be opened against inlet pressure of 100 psi (689 kPa) [6.89 bar]. Standard models include an escape vent for gas trapped forward in the line after shut-off. M5081FS Normally Energized Circuit The M5081FS is manually opened, electrically latched open and tripped by interrupting the coil power circuit. Magnetic Switch Adapter As ignition systems wear from usage, their power output becomes less and less. Ignition may not have the capacity to reliably trip the Fuel Valve. Therefore, the use of a Magnetic Switch Adapter for CD ignition systems is recommended. The Magnetic Switch Adapter is a device that stores energy from the CD ignition to trip the Fuel Valve. Three models are available: 65700053 (was 65020126): For use with negative ground ignitions up to 240 VDC. 65700054 (was 65020127): For use with positive ground ignitions up to 450 VDC. 65700055 (was 65020155): For use with negative ground ignitions up to 450 VDC. 100 ohm, 2 watt Resistor For Capacitor Discharge Ignitions that are specified to be grounded when the valve closes, and a Magnetic Switch Adapter is in use. The resistor must be connected in the system to prevent damage to the snap-switches in the fuel shut-off valve (see typical wiring diagrams). Diode Package The Murphy diode package (65010065) is designed to allow the fuel shutoff valve to be used with dual Magneto Ignition systems. NOTE: All aluminum versions of the M5081 Series Fuel Valve carry Canadian Registartion Number OC1476.2. * M5081 model is CSA approved for Class I, Division 1, Groups C and D.
