Directional

Direct-acting, 3-way directional cartridges (1 blocked, 2 to 3 open) 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.

• Port 3 can be used as a work port.
• Because of their direct-acting design, these cartridges feature low internal leakage and low pilot flow consumption.
• 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.
• 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.
