pressure Relief Valves
A pressure relief valve is a safety device designed to protect a pressurized vessel or system during an overpressure situation – when the system is increased beyond the specified design pressure or maximum allowable working pressure. Reliability of the pressure relief device is pertinent, hence its simplistic and compatible design.
Dresser’s patented Flow Safe product line offers a variety of pressure relief valves, made to order per customer specifications.
