Pressure limiting valves type CMV and CSV

The types listed are intended for the following purposes:

• Pressure limiting valve (safety valve):

Safeguarding the system against excessive pressure or for the limitation of working pressure.

• Sequence valves: generating a constant pressure difference between inlet and outlet of the flow. The flow in opposite direction (reflow) is unhindered via a by-pass check valve.

A significant advantage of these valves is their easily to manufacture mounting hole (see dimensions).

Type CMV is also available as a pressure limiting valve with unit approval

(CE), e.g. required for safety valves for accumulators (EC regulation 97/23). The CE-logo is applied to these valves.
