    About Pressure-Relief Valves
    industrial info icon

    Choose the correct valve type and pipe size to safely manage the pressure of your system.

    Made-to-Order Pressure-Relief Valves

    Design a valve specifically for your process media and set pressure. Choose from a valve for air, inert gas, water, hydraulic oil, fuel oil, gasoline, or diesel fuel and a set pressure. These valves begin opening at the set pressure and fully open at about 10% over the set pressure. They begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Body is 316 stainless steel for exceptional corrosion resistance.
