Pilot operated check valves series ZRE in size NG06 (CETOP 03) and NG10 (CETOP 05) are part of Parker’s complete range of sandwich plate valves and ensure the easy configuration of conventional stack systems. They provide maximum flow rates up to 120 l/min and long lifetime. ZRE valves are typically used in combination with spool type directional control valves to enable an almost leak-free positioning of the actuator.
The inlet flow is free while the outlet flow is blocked. Pressure in the inlet line opens the check valve and allows free outlet flow.
