Pressure Relief Valves (PRV) for General Purpose Cars
High-Flow Pressure Relief Valve
As the regulations change to include higher flow requirements for a 75-psi valve, Midland has developed its valve to meet the needs of the industry. The A-22075 Pressure Relief Valve is designed to work with a variety of commodities, in addition to satisfying the requirements of the new regulations. The construction of the A-22075 is carbon steel with a stainless-steel stem and retainer to help reduce the possibility of corrosion.
Also available as part of Midland's convenient DOT 117/117R solutions, designed to help customers meet the latest requirements for high-hazard flammable trains (HHFT) and high-hazard flammable unit trains (HHFUT).
