MODEL

DPCP

3-way, pilot-operated, directional valve with drain to port 4 (1 to 2 open, 3

blocked)

SERIES 2 / CAPACITY: 60 L/min. / CAVITY: T-22A

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

Pilot-operated, 3-way directional cartridges (1 to 2 open, 3 blocked) are switching devices typically used in

moderate flow circuits. They can be used by themselves or to actuate larger pilot operated directional cartridges or

logic cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.

TECHNICAL FEATURES

Port 4 can be blocked to prevent the valve from shifting.

Port 3 can be used as a work port.

Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.

Pressure at port 4 is directly additive to the setting of the valve.

This valve is not bistable; it is capable of modulating between the two positions shown.

Maximum pressure at port 3 should be limited to 3000 psi (210 bar). This is due to fatigue strength limits not hydraulic operating limits.

When pilot pressure exceeds the valve setting, pilot flow may be a consideration. See performance curves for pilot consumption vs. load pressure above the valve

setting. If this is a problem, the direct acting version of this valve would be a solution.

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.
