Automatic Air Release Valve
The BT 5231 Automatic Air Release Valve is designed to automatically release trapped air from pressurised fire protection and water distributionsystems during normal operation. By continuously removing accumulated air, the valve helps maintain efficient water flow, reducespressure losses and protects the pipeline from air pockets. The valve incorporates a stainless steel float and lever mechanism that operates the discharge orifice under full pipeline pressure,
providing reliable and maintenance-friendly performance.
