    Pressure Relief Valves for Cylinders are essential safety devices designed to protect unvented and sealed hot water cylinders from excessive pressure build-up. By automatically releasing water when pressure exceeds safe levels, these valves prevent damage to cylinders, pipework, and associated heating systems.

    About Pressure Relief Valves

    Pressure relief valves are installed on hot water cylinders to safeguard against over-pressurisation caused by thermal expansion or system faults. They typically feature a spring-loaded mechanism that opens when pressure reaches a preset limit, discharging excess water safely. These valves are available in various sizes and pressure ratings, suitable for both domestic and commercial applications.
