Ventable, Pilot Operated, Balanced Piston SRV4

General Description
  1. Maximum operating pressure = 5000 psi
  2. Pressure at port 3 (vent) controls the valve below its setting.
  3. Back pressure on the tank port (port 2) is directly additive at a 1:1 ratio to the valve setting.
  4. Control pilot flow = SRV4 - 3, SRV4 - 6: 0.11 L/min. to 0.16 L/min.; SRV4 - 12: 0.16 L/min. to 0.25 L/min.; SRV4 - 24, SRV4 - 48: 0.25 L/min. to 0.33 L/min.
  5. Factory pressure setting established at 15 L/min.
  6. Typical response time 10 ms.
  7. Maximum leakage = SRV4 - 3, SRV4 - 6: 32.8 cc/min/1000 psi, SRV4 - 12: 49.2 cc/min/1000 psi, SRV4 - 24: 65.5 cc/min/1000 psi, SRV4 - 48: 81.9 cc/min/1000 psi.
  8. SRV4 - 3 minimum setting for all spring ranges is 72 psi.
  9. Will accept maximum pressure at port 2.
  10. Adjustment Range = 'DR' & 'YL' are standard set at 1000 psi
