    ASME-Code Fast-Acting Pressure-Relief Valves for Low-Pressure Steam

    For use with low-pressure steam-heating boilers requiring pressure relief at 15 psi, these valves meet ASME Code Section IV. All spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. Body is bronze for durability and a long service life.

    Large-Diameter Remote-Discharge ASME-Code Fast-Acting Pressure-Relief Valves for Air and Inert Gas

    These valves meet ASME Code Section VIII for use with air and inert gas pressure vessels. Commonly used with high-volume blowers, compressors, and air-powered conveyors, they quickly relieve a large amount of air in systems with a pipe size of 2 or greater. They spring fully open at the set pressure and remain open until the system pressure is restored below the set pressure. Attach a drain line to the threaded relief port for remote discharge. Valves have a cast iron body to absorb vibration for reduced noise and wear in your pipeline.

    Precision-Adjustment Pressure-Relief Valves for Fuel

    A finely threaded adjustment screw lets you make precise set pressure adjustments. These valves are for use with diesel fuel, fuel oil, gasoline, and kerosene. They begin opening at the set pressure and fully open at about 10% over the set pressure. Valves begin closing as pressure drops and fully close when the system pressure is restored below the set pressure. Adjust the set pressure within the range.
