Description
An adjustable, pilot-operated spool cartridge valve designed to direct oil to a circuit when a predetermined pressure has been reached.
Operation
The DPSK-080 in steady state blocks flow at ➀ while allowing flow from ➁ to ➂. When the preset pressure at ➀ is achieved, the pilot section opens. This pilot flow creates a pressure differential across the spool, which causes the spool to shift to allow flow from ➀ to ➁.
The spool will not shift back (kick-down) until pressure at ➁ falls below a predetermined pressure.
Features and Benefits
- Hardened precision spool and sleeve for long life.
- Variety of pressure ranges.
- High accuracy of pilot operated design.
- Adjustment prevents spring from going solid.
- Adjustment may be locked in place.
- Hidden adjustment option.
- Industry common cavity.
