Pressure Reducing Valve

Spool Type, Pilot Operated

Metric Cartridge Valve – 350 bar

DRM10130P-01

Up to 150 l/min

Up to 350 bar

The pressure reducing valve

DRM10130P is a pilot-operated, 3-way

spool-type valve.

If the pressure across port 1 exceeds

the pre-set value, the pilot-stage opens

and oil ows from behind the main spool

to the tank port 3. The resulting pressure

differential causes the main spool to

move against the reset-spring and

allows oil to ow from port 2 to port 1.

This continues until the system pressure

is equal to the spring tension and the

valve closes again.

If the pressure at port 1 suddenly

rises due to external force the valve

is relieved to tank port 3 (maximum

pressure relief).

Any pressure at port 3 is additive to the

pressure setting.

GENERAL

z Excellent stability throughout the entire ow range

z External surfaces zinc-plated and corrosion-proof

z Hardened and ground internal valve components to ensure minimal wear and

extended service life

z Low pressure drop due to CFD optimized ow path

z Adjustable throughout ow range

z Screen protected metering orice enhances safety

z Optional spring ranges up to 350 bar
