| PARALLEL SLIDE Gate Valve, Cast High Pressure |
| Features & Benefits: |
| Excellent Reliability |
- Eyelet Follower providing a smooth flow path & maximum performance Self cleaning action between disk & seat
- Welded-in seats hard-faced with Stellite® or Equivalent
- Seat surface protection provides extended life
- Low Cost Maintenance
- Expanded graphite pressure seal & gland packing
- Lower operating forces than wedge gate design
- Interchangeability of parts
- Simplified seat refurbishment (only requires flat lapping, no critical angles to be matched to ensure sealing capability)
- Longer seat life with eyelet follower, due to reduced erosion
|
| Improved Performance |
• Lower pressure drop characteristic than wedge gate valve
• Minimized flow turbulence
• Reduced actuator size/cost by 30% when compared to wedge gate
• Higher allowable seat velocity
• Improved sealing assisted by line pressure
• Low operating torque, seals on position not torque
|
| Typical Applications |
• Main Steam Isolation
• Boiler Feed Pump Isolation
• H.P. Feed Heater Isolation & By-Pass
• Blow Down Service
• Blow Off Service
• Gland Steam System Drains
• Steam Turbine Inlet Isolation
• Economizer Recirculation
• Spray Water
