Hayward RELIEF VALVE CZ,HM2,CPS,PSG,SG

A Hayward Relief Valve for CZ, HM2, CPS, PSG, and SG models is a safety‑focused component designed to release excess pressure within compatible pool filtration or heating systems, helping protect equipment from damage caused by blockages, restricted flow, or abnormal operating conditions. It opens automatically when internal pressure rises beyond a safe threshold, allowing water to bypass temporarily until normal conditions return. Built from durable, corrosion‑resistant materials, it withstands chlorinated water, heat, and outdoor exposure while maintaining reliable performance over long service cycles. Despite its critical role in system protection, the valve remains compact and easy to install, with an estimated weight of about 0.2–0.4 pounds, depending on the specific version
