Groth Corporation’s Manway Emergency Relief Valves are  designed to provide emergency relief capacity beyond that furnished by the normal operating pressure relief valve on the tank. The valve protects the tank against rupture or explosion that could result from excessive internal pressures caused by fire, etc.


Multiple Manway models available.

Featured is the Groth 2100

  •  High Pressure Emergency Relief Valve
  •  Sizes: 16″, 20″ and 24″
