Pilot-operated check valves

Plate-type, screw-in design
Series ERVH

Pilot-operated check valves prevent any flow in one direction. In the opposite direction, free flow with minimal pressure drop is possible. By applying a defined pilot pressure at X, the checked flow direction is held open as long as the pilot pressure is maintained.

Advantages

• High pressure rating
• Virtually zero leakage
• Compact construction
