Aquatrol 740 Series safety relief valves are designed to open when the pressure exceeds the stress limits and prevent pumps and pipelines from fire accidents or system failure. These units feature a brass / bronze body for strength, ductility, malleability and corrosion resistance and a full-nozzle design flanged to the pressurised system. They are further integrated with a stainless-steel disc for enhancing seating tightness and preventing flow under ambient operating conditions, and an adjustable nozzle ring for controlling the fluid exit. They meet ASME Section VIII standards and are ideal for air / gas, liquid and steam applications. Choose from a wide range of these safety relief valves available in factory set pressures ranging from 15 to 300 psi on Raptor Supplies.
