Pressure Relief Valve Screwed
The Pressure Relief Valve (Screwed End) is designed to protect pipelines, vessels, pumps, and other pressurized equipment from overpressure conditions by automatically releasing excess pressure once the preset limit is reached. Its compact design and BSP/NPT screwed end connections ensure easy installation, reliable operation, and low maintenance. Suitable for air, gas, steam, water, oil, and various process fluids, this valve is widely used in industrial, chemical, HVAC, and utility applications, providing dependable system safety and long service life.
