The Glow-worm 0020275016 Pressure Relief Valve (PRV) is a genuine safety component designed to protect your heating system from dangerous over-pressurisation. When boiler pressure exceeds safe operating levels, the PRV automatically releases excess water, preventing damage to internal components, pipework, and radiators.

A faulty PRV can cause continuous pressure loss, dripping discharge pipes, or repeated boiler shutdowns. Replacing it with this genuine Glow-worm 3-bar valve restores safe system operation and reliable pressure regulation.
