Industrial 0031EDA Three Way Proportional Valve

The Spence 0031EDA-100 Safety Relief Valve is a bronze-bodied device with a 3/4 in NPT inlet and a 1 in NPT outlet, engineered for steam and non-hazardous gas service with a set pressure of 100 psi and a relief range of 10–250 psi (maximum 250 psi). This 0031EDA-100 model combines a bronze body and disc, EPDM seat, and a stainless-steel spring to provide reliable overpressure protection in industrial systems. Inlet and outlet sizes are specified as 3/4 in NPT and 1 in NPT respectively, making it suitable for OEM equipment, pressure-reducing stations, steam boilers, and receivers. The valve measures an overall height of 7 1/8 in and an overall length of 3 in, designed for installation in compact steam-return and supply configurations. Typical applications include protection of steam boilers, pressure-reducing stations, and related equipment in commercial and industrial facilities, where precise relief characteristics and robust bronze construction are valued for long-term performance.
