Pressure Retaining Valve

Pressure Retaining Valve – Overview

This valve works to keep the pressure at the valve inlet constant at all times ensuring problem-free operation and eliminating the risk of overload. It is made of fully molded, high-grade plastic, making this the obvious choice for any piping system. It contains the latest in pressure-regulating technology, these valves are compact and easy to install and can be configured to either reduce or retain the pressure. The innovative cartridge design minimises maintenance.
