The Grundfos BVF valve is a one-way valve with the valve casing made of cast iron. The valves have a BSP internal pipe thread and are supplied with a spring-loaded valve cone.

BVF valves are used in minor water supply and pumping systems to avoid backflow when the pump is stopped. The valves are also fitted in systems where the pumps are connected in parallel and as foot valves to secure the suction conditions of the pumps.
Valves with a spring can be fitted in any position in the pipe system.

Maximum operating pressure: 25 bar.
Liquid temperature: 0 °C to +70 °C
