Features and benefits

This valve is designed for continuous blowdown but can also be used for sampling and boiler feed pump bypass relief where high pressure drop causes erosion and cavitation which can destroy conventional globe valves. It incorporates a hardfaced CoCr alloy disc and seat and aventuri diffuser from stainless steel type 316. Orifice range: 1⁄8 to 1 1⁄8" (3.18 to 28.58 mm), depending on the capacity required.
