BT 5931A

The BT 5931A Angle Pressure Relief Valve is a pilot-operated automatic control valve designed to protect fire protection pumping systems from excessive pressure. Installed in an angle-pattern body, it automatically relieves excess discharge pressure and maintains a constant system pressure as flow demand changes. Its accurate pressure regulation ensures reliable system performance, protects pumps and piping from overpressure, and enhances overall system safety. The valve is manufactured from high-quality materials for long service life and is available with an epoxy-coated body for superior corrosion resistance in demanding fire protection applications. The BT 5931A Pressure Relief Valve delivers highly stable pressure control while operating smoothly over a wide flow range. Additionally, its advanced hydraulic design features quick opening capabilities to immediately relieve dangerous pressure spikes, paired with an adjustable closing speed to prevent water hammer and protect the system from sudden shocks.
