NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.

Ventable, pilot-operated pressure reducing/relieving valves reduce a high primary pressure at the inlet to a constant

reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). The vent port (port 4) can be

used as a means for remote control by pilot or 2-way valves.

TECHNICAL FEATURES

Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 3000 psi (210 bar).

Pilot operated reducing, reducing/relieving valves by nature are not fast acting valves. For superior dynamic response, consider direct acting valves.

Pilot operated valves exhibit very low dead-band transition between reducing and relieving modes.

Recommended maximum inlet pressure is determined by the adjustment range. Ranges D, E, N, and Q are tested with a 2000 psi (140 bar) maximum differential

between inlet and reduced pressure. Ranges A, B, and H are tested with a 3000 psi (210 bar) maximum differential between inlet and reduced pressure. Ranges C

and W are tested with 5000 psi (350 bar) of inlet pressure.

Pilot operated valves exhibit exceptionally flat pressure/flow characteristics, are very stable and have low hysteresis.

By controlling the pressure at the vent (port 4), the effective setting of the valve can be controlled below the nominal valve setting.

Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge

machining variations.
