Parallel Slide Gate ValvesLow pressure Cast Steel Features & Benefits • Excellent Reliability - Self cleaning action between disk & seat - Welded-in seats hard-faced with Stellite® or Equivalent - Low Cost Maintenance - Lower operating forces than wedge gate design - Interchangability of parts - Simplified seat refurbishment (only requires flat lapping, no critical angles to be matched to ensure sealing capability) • Improved Performance - Lower pressure drop characteristic than wedge gate valve - Reduced actuator size/cost by 30% when compared to wedge gate - Improved sealing assisted by line pressure - Low operating torque, seals on position not torque • Typical Applications - L.P. Steam Isolation - Boiler Feed Pump Isolation - L.P. Feed Heater Isolation & By-Pass - Blow Down Service - Blow Off Service - Gland Steam System Drains - Steam Turbine Inlet Isolation - Economizer Recirculation - Spray Water - Attemperator Spray - Steam Blow and Start Up Technical data Sizes : 10” – 20” ASME : B16.34 – 1996 Valve overall lengths to : ASME B16.10 – 1992 Pressure Class : 600 Tyco reserves the right to change the contents without notice DEWDR-0004-EN-0205 8 17.4 84.7 89.4 77.6 77.4 103.4 103.
