2-way, pilot operated, directional valve with internal drain to port 3 - normally
closed
SERIES 2 / CAPACITY: 60 L/min. / CAVITY: T-2A
Normally closed, pilot-operated, 2-way directional cartridges 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 3 exceeds the setting.

TECHNICAL FEATURES
Pressure at port 3 is directly additive to the setting of the valve. Because of this, port 3 may not be useable as a work port in your circuit. If this is a consideration,
the 4 port version of this valve may be a solution.
Direct-acting and pilot-operated versions of these valves are interchangeable. They fit the same cavities and have the same flow paths.
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.
For Series 1 cartridges configured with an O control (panel mount handknob), a .75 in. (19 mm) diameter hole is required in the panel.

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.
