Product Description

Product Parameters

W

The WR31 series stands out as a High Pressure High Flow Reducing Regulator, blending cutting-edge technology with robust specifications. Technical data highlights 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, internal components include a PCTFE valve seat, FKM O-ring, and 316L piston, ensuring resilience against extreme temperatures from -40ºC to +74ºC (-40°F to +165°F). A hallmark of quality, its leak-proof design ensures no visible air bubbles internally or externally, as verified with Helium. The flow coefficient (Cv) is an efficient 2.0, and the valve body ports feature 1/4NPT Inlet and Outlet, as well as a 1/4NPT pressure gauge port. Adhering to the highest standards, the product is cleaned and packaged following AST G93 Class C cleaning requirements. Key features include suitability for high-pressure, high-flow applications in hydrogen energy, a piston sensing design offering greater outlet pressure adjustment, and optional use in oxygen-rich environments. Designed for excellence, this regulator is a testament to precision engineering and adaptability.
