Pressure reducing valves without leack-oil connection

Pressure reducing valves are ideal for the application in static leak-oil free

clamping systems, which are decoupled by the pressure pump unit.

The function of the pressure reducing valve is to maintain the outlet 

pressure on the consumer also with variable, always higher inlet 

pressure constant.

Once the inlet pressure equals the set outlet pressure, a check valve 

completely blocks the oil flow. Therefore, the pressure can not increase

any more. Until the set-up outlet pressure is acquired, the hydraulic oil 

can easily flow through the valve.

A pressure spring opens the oil flow against the inlet pressure, 

as soon as the outlet pressure, e. g. due to the consumer, decreases. 

This makes the hydraulic oil flow until the initial pressure is acquired again
