W627 Liquid Gas Regulator

Product catalog summary

Overview: The W627 is a robust, spring-loaded, direct-operated regulator designed for liquid service. It features a durable powder-coated epoxy exterior and offers installation versatility with multi-position body and spring case configurations. An external pressure registration model, the P627M, is also available.

Applications: This regulator is suitable for use in industrial chemical processes, chemical production, and electronic manufacturing.

Specifications:

Pressure Ratings: The maximum bonnet and diaphragm casing pressure varies with material options (Iron, Steel, Stainless Steel) to prevent leaks and bursts.
Differential Pressure: Maximum differential pressure is 200 PSIG for elastomer and 400 PSIG for nylon.
Outlet Range: The outlet pressure ranges from 10 to 500 PSIG, with various body and orifice sizes available.
Temperature Range: Operates effectively between -40˚ to 180˚F (-40˚ to 82˚C).
Materials: Options include Stainless Steel, Steel, Iron, and LCC Steel for the body, bonnet, and diaphragm case.

Rebuild Kits: Kits are available for both low and high-pressure applications, featuring different diaphragm and valve disk materials.

Flow Capacities: The document includes detailed tables showing water flow capacities in GPM and Cv coefficients for various outlet pressure ranges and body sizes.
