Pressure Relief Valves

PRESSURE RELIEF VALVES (70- Series) - Cipriani Harrison’s Pressure Relief Valves are made from forged 316L stainless steel, are highly polished, come standard with PTFE seats and EPDM seals. These valves have self-draining machined bodies with a round shape that allows for a minimum resistance to flow. The valve body, yoke and spring housing are assembled with clamps enabling a quick and easy assembly or disassembly. Available in sizes 1”– 3“ with Sanitary Clamp and Butt-Weld end connections as standard. A manually adjustable spring closing force allows for a desired pressure rating to be set. Once the line pressure reaches this set point the valve plug will lift and the pressure will be relieved through the side port. These valves are 3A authorized.
