Henry 5240-400 Relief Valve

• Type: Straight-Through (St.-Thru) Relief Valve
• Material: Brass
• Inlet Size: 1/2" Male Pipe Thread (MPT)
• Outlet Size: 3/4" Female Pipe Thread (FPT)
• Application: Designed for use in refrigeration systems to prevent over-pressure due to system malfunction or excessive external heat. Suitable for refrigerant vapor or gas.
• Pressure Setting: Typically set to a specific pressure rating as required by the system specifications.
• Features:
  • Center Loading Pivot: Ensures the piston reseats squarely to the body seat, reducing leakage.
  • Compatibility: Suitable for use with refrigerants such as R22, R134a, R404a, R410a, R500, R502, and other industrial fluids non-corrosive to brass, steel, and Teflon.
  • Construction: Brass valve body with internal parts made of brass and carbon steel.
  • Operation: The valve is designed to discharge vapor and should not be used to vent liquid refrigerant. It is back-pressure dependent and discharges to the atmosphere.
  • Installation: Typically installed on the top section of a pressure vessel, such as a liquid receiver or suction accumulator. Should be mounted vertically and replaced after opening to full discharge
