It discharges residual pressure of oil‑gas separator tank during unloading, prevents heavy‑load startup of motor with high internal pressure.
Part numbers marked "replacement" are not affiliated with the original manufacture.
Main Features
Voltage:AC110‑120V 50/60Hz;Max working pressure 17bar(250PSI);Working temperature:‑20℃ ~ +85℃
Function:blow‑down residual pressure of sump tank when compressor unloads; realize pressure relief before restart
Common faults:pressure cannot drop after unloading, motor heavy‑load startup, continuous air blow‑by, coil burnout, spool stuck
Applications
Maintenance suggestion: confirm coil voltage before installation; renew thread sealing gaskets; prevent oil‑water entering control pipeline; replace full valve assembly when spool stuck or internal leakage occurs
