Features of IRSDC-LBN Sequence Valve

1. On attainment of a preset pressure on port ① (inlet), which is related to the pressure on port ③ (drain), the pilot-flow increases.

2. The orifice of the main stage is protected by a 150μm stainless steel screen.

3. The pressure on port ③ will directly (1:1) affect the valve's setting value, and cannot exceed 5000 psi (350 bar).

4. Due to the leakage of spool, it is not suitable for use for load lock application.

5. The retaining ring on the adjusting rod limits the adjustment stroke to prohibit springs from going solid.

6. Hardened spool and cage for long life.

7. Compact structure for long life.

Operation Symbol of IRSDC-LBN Sequence Valve

The piloted sequence valve with balanced spool will supply oil to the secondary circuit once a preset pressure is attained on inlet ①. The setting of the sequence valve will control the pressure on port ① related to the pressure on the drain port ③. This type of valve is not sensitive until the back pressure on port ② (sequence port) rises to the preset pressure. If there is pressure in the circuit, it can be used to replace the relief valve of port ② to adjust the pressure.
