Rwc 22999-0045 1/2 Inch Iron Pressure Regulating Valve

Product Description

The RWC 22999-0045 is a 1/2-inch iron pipe pressure regulating valve designed to control and stabilize incoming water supply pressure in residential plumbing systems. The valve features a cartridge-based internal design that simplifies field service and reduces repair time. Outlet pressure is adjustable across a range of 20 psi to 75 psi using a straightforward cap-twist mechanism, requiring no special tooling. Replacement cartridges are available separately, allowing a licensed plumber to restore the valve to factory performance without replacing the full assembly. This valve is sized for 1/2-inch iron pipe connections and is suited for point-of-entry pressure management.

This pressure regulating valve is intended for residential water supply applications where incoming line pressure must be reduced to a safe, code-compliant level before distribution through the structure. Typical installation locations include the main water service entry point or branch lines serving fixtures and appliances sensitive to high pressure. The cartridge design is well suited to service environments where quick turnaround is a priority.
