Technical data
Pilot operated check valves series ZRE are designed for
maximum ļ¬‚ow rates and long life time.
The valves are typically used in combination with spool
type directional control valves to ensure nearly leak free
positioning of the actuator.
The inlet ļ¬‚ow is free while the outlet ļ¬‚ow is blocked.Pres-
sure in the inlet line opens the check valve and allows
free outlet ļ¬‚ow.
Features
ā€¢ High ļ¬‚ow capacity
ā€¢ High life time
ā€¢ Check function in A, B or A + B
