Description
A Pressure Relief Valve is a vital safety device designed to automatically release excess pressure from pipelines, tanks, or systems, preventing overpressure conditions. When system pressure exceeds the set limit, the valve opens instantly to discharge excess fluid or gas, and closes once normal pressure is restored, maintaining safe operation.
PRVs are essential in fire protection systems, water supply networks, HVAC systems, industrial pipelines, and chemical plants. Constructed from high-quality materials like Stainless Steel, Carbon Steel, and Brass, they offer durability, corrosion resistance, and reliable performance. Adjustable set points ensure precise pressure control, protecting equipment, preventing accidents, and complying with safety standards.
