Parker ZRE pilot operated check valves are designed for maximum flow rates up to 120 litres/minute over a long lifetime.
The valves are typically used in combination with spool type directional control valves to ensure nearly 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.
Parker ZRE check valves are available in two sizes:
- ZRE01 – NG06 (cetop 03)
- ZRE02 – NG10 (cetop 05)
Features and benefits include:
- Compact, proven design – ensures reliable operation in conventional stack systems
- High flow capacity – provides optimum efficiency in relation to valve size
- Long lifetime – offers a very good price-perfomance ratio
- Check function in A, B or A + B
