Low Pressure Parallel Slide Gate Valve
FEATURES & BENEFITS
Excellent Reliability
Self cleaning action between disk & seat
Welded-in seats hard-faced with STL? or Equivalent
Low Cost Maintenance
Lower operating forces than wedge gate design
Inter-changeability 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
Higher allowable seat velocity
Improved sealing assisted by line pressure
Low operating torque, seals on position not torque
