- Mechanical Directional Control Valves
- Pilot Operated Check Valves
- Pilot to Open
- 3-Way, 2-Position
- With no pilot signal at port (1), port (2) is blocked and flow is allowed between port (3) and (4)
- With the required pilot signal applied to port (1) the valve shifts to allow flow between (3) to (2) while blocking flow at port (4)
- The bias spring which is common to port (4) retruns the spool to its original position when the pilot signal is removed
- Pressure at port (4) must be considered when determining the required pressure to shift
- Hardened parts for long life
- Industry common cavity
