This is a hydraulically released check valve with spring closing and with cone on edge seals; the mounting surface is according to the ISO 4401 standards.
Its use allows:
-prevention of flow in one direction;
-flow in the same direction, if opened by a pilot pressure;
-free flow in the other direction.
The CHM7 valves are always mounted downstream of the DSP7 type directional solenoid valves (see cat. 41 420) and can be assembled with all other ISO 4401-07 valves.
