Direct-acting, 3-way directional cartridges (3 to 4 open, 2 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

Note: 800 psi (55 bar) is the highest setting possible with this valve.

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

The flow path between port 2 and port 3 is bidirectional.

Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.

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

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.
