The PS10-34 is a screw in, cartridge style, spool type, hydraulic sequence valve with internal pilot and spring chamber drain.
In its steady state, the PS10-34 blocks flow from port 1 to port 2, with the spring chamber drained at port 3. On attainment of a predetermined pressure at port 1, the cartridge shifts to open port 1 to port 2. The valve will remain shifted until the pressure in the circuit falls below the pressure setting. Note that the back pressure on port 3 adds to the spring setting value.
- Adjustments cannot be backed out of the valve.
- Adjustments prohibit springs from going solid.
- Optional spring ranges to 117.2 bar (1700 psi).
- Hardened spool and cage for long life.
- Industry-common size.
