Direct-acting, pressure reducing valve

SERIES 2 / CAPACITY: 80 L/min. / CAVITY: T-2A

Direct-acting, pressure reducing valves reduce a high primary pressure at the inlet (port 2) to a constant reduced

pressure at port 1. These valves incorporate a damped construction for stable operation allowing the use of high

TECHNICAL FEATURES

Note: This valve has no relieving capability. It should not be used in a dead-headed application. If the reduced pressure side of the circuit has very low leakage the

pressure may rise significantly. The pressure rise will vary from valve to valve.

This type of valve, PR*R, is a good replacement for an LP*C as a normally open, restrictive compensating element if a higher pressure drop across an orifice is

needed.

Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.

Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the main spool to close. If reverse free flow is required in the circuit, consider adding a
