Product Description

Product Parameters

W

Introducing the WR31 Series: A High-Pressure, High-Flow Reducing Regulator with impressive technical specifications. This robust regulator boasts a maximum inlet pressure of 4500psig/6000psig, with versatile outlet pressure ranges of 0~300, 0~600, 0~1000, 0~1500, and 0~2500 PSIG. Crafted with precision, its internal components include a PCTFE valve seat, FKM O-ring, and a durable 316L piston. Engineered to operate in extreme temperatures from -40ºC to +74ºC (-40°F to +165°F), it ensures reliable performance with no visible air bubbles, both internally and externally, when tested with helium. The flow coefficient (Cv) is a remarkable 2.0, complemented by inlet, outlet, and pressure gauge ports all sized at 1/4NPT for seamless integration. For uncompromised purity, each product is meticulously cleaned and packaged according to AST G93 Class C cleaning standards. Key features include compatibility with high-pressure and high-flow hydrogen energy applications, a piston sensing design that offers an expansive outlet pressure adjustment range, and optional suitability for oxygen environments. Perfect for standard and non-corrosive gases, the WR31 Series is your go-to solution for demanding applications.
