Pressure limiting valves type CMV and CSV - HAWE Hydraulik - #1

Text version of the page

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. Type CMVZ und CSVZ are not influenced by the pressure conditions downstream i.e. sequencing control without losses.
