How to choose HAWE pressure valve (CMV CMVZ、CSV、CSVZ)

Overview of German Hawei CMV, CMVZ, CSV, CSVZ pressure valves: Pressure limiting valves and differential pressure reducing valves belong to the pressure valve category. The pressure limiting valve prevents exceeding the limit of the maximum allowable system pressure or working pressure. The differential pressure reducing valve generates a constant pressure difference between the flow inlet and outlet. How to choose HAWE pressure valve (CMV CMVZ、CSV、CSVZ):


product type

CMV type pressure limiting valve

·Prevent exceeding the maximum allowable pressure of the equipment (safety valve) or limiting the working pressure.


CMV type pressure limiting valve X-undamped type

·Used for special operating conditions, such as preventing the climb of the cylinder chamber pressure when the temperature rises, or the forced climb movement of the valve core due to external forces.

·The difference in hysteresis between opening and closing pressure is very small.


CSV type differential pressure reducing valve (pre pressure valve)

·As long as there is flow passing through, a basically constant pressure difference will be generated between the input and output.

·Reverse flow (return oil) can be achieved through a bypass check valve.


CMVZ and CSVZ type sequential valves

·The switching pressure (opening pressure) is basically independent of the discharge side pressure,

·Suitable for sequential switching
