Why Choose a Water Pressure Reducing Valve?

A Water Pressure Reducing Valve (PRV), with a back-flow restriction device, is a crucial component for any water filter or reverse osmosis system under constant mains water pressure. It is a regulatory requirement in Australia, as per standard AS3497. This valve protects your water filtration system from high water pressure, which can damage filters, fittings, and other components, ensuring the longevity and reliable performance of your unit.

Compact Design and Powerful Performance

This PRV is available in two pressure ratings: 350kpa and 550kpa. The valve is designed to reduce and regulate the incoming water pressure to a safe level for your filtration system. It also includes a back-flow restriction device, which prevents filtered water from flowing back into the main water supply, protecting the purity of the public water system. The valve is a compact and essential safety device for your water filter. It is Watermark certified and designed to be fitted in-line with your system using 1/4" (6mm) tubing and quick-fit push-in connectors.

Seamless Integration and Easy Maintenance

This valve is designed for straightforward installation and integration into your water filter system. It is a mandatory safety component that ensures your system operates within its recommended pressure range. The product description highlights the importance of this device for complying with regulatory standards and for protecting your investment in a water filtration system. It is also backed by a 12-month warranty.
