The pressure reducing valve DMVE is a
direct acting, spring-loaded spool valve. Its
function is to maintain a constant pressure
at the consumer.
In the normal position, pressure port 2 is
connected to consumer port 1.
The pressure build-up at the consumer
acts on the face of the control piston
and moves it upwards against the set
springforce. Therefore the inow is
throttled at port 2 just enough to satisfy
the consumers demand - without pressure
increase.
An additional function is the outlet pressure
relief: if the pressure across the consumer
port 1 rises above the control pressure
due to external force, the control piston
is pushed further against the spring and
relieves the consumer to tank port 3.
z Excellent stability throughout the entire ow range
z Excellent dynamic performance
z All valve parts made of high-strength steel with hardened and ground components
to ensure minimal wear and extended service life
z Low pressure drop due to CFD optimized ow-path
z Low hysteresis and good stability throughout ow range
