This solenoid-operated 2-way, 2-position cartridge is a direct-acting, poppet-style directional valve. The valve is available in either a normally open or normally closed configuration. Due to the poppet style construction, this valve has extremely low leakage.
The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service
This valve is direct actuated and requires no minimum hydraulic pressure for operation
Valves exhibit extremely low leakage rates less than 10 drops/min at 5000 psi (0.7 cc/min at 350 bar)
This cartridge has several manual override choices, including no manual override
This valve is suitable for load holding applications when using the normally closed option
In the event of power failure, the valve will spring closed
On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation
The D, L and T manual control assembly has a mechanical life expectancy of approximately 7000 cycles
Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids
Exposure to petroleum based fluids, greases and lubricants will damage the seals
This valve utilizes a wet armature design
The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per watt expended, leading to reliable valve shifting
Coils are interchangeable with other sun series 1 solenoid products and can be mounted on the tube in either direction
Coil connector options offer ratings up to IP69K
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
