HSV12-20 HyPerformance™ Poppet, 2-Way,

DESCRIPTION

A solenoid-operated, 2-way, piloted, normally closed, poppet-type, screw-in hydraulic

cartridge valve, designed to function as a load holding or blocking valve in high-pres-

sure applications requiring low internal leakage.

OPERATION

When de-energized, the HSV12-20 blocks flow from ports 2 to 1. In this mode, the

cartridge will allow flow from ports 1 to 2 after overcoming the spring forces (see

performance graph). When energized, the valve will allow flow from ports 2 to 1 while

severely restricting flow from ports 1 to 2.

Operation of Manual Override Option: The manual override feature is intended for

emergency use, not continuous duty operation. To operate, the manual override pin

must be seated in the lower detent groove. To shift the valve manually, the opera-

tor pushes down on the knob and rotates 180 degrees in either direction. When the

manual override is actuated, increased flow can be achieved by pulling on the knob.

FEATURES

• Continuous-duty rated solenoid.

• Hardened seat for long life and low leakage.

• Optional coil voltages and terminations.

• Efficient wet-armature construction.

• Cartridges are voltage interchangeable.

• Manual override option.

• Waterproof E-Coils rated up to IP69K.

• Unitized, molded coil design.

• Cost effective cavity.

• All HyPerformance products are tested to the rigorous standards

of the NFPA specification T2.6.1.

• All HyPerformance valves are tested at a verification level of 90%

and an assurance of 99%.
