The valve can be fitted in any position required.
2. Non-return valves, type GNV GNV non-return valves are designed for installation in pipe systems between two DIN flanges. The valve casing is made of electro-coated cast iron. Valve cone, valve seat and other components are made of stainless steel. Applications GNV 50, 80 and 100 are used in Grundfos booster systems, in water supply systems and drainage systems in both dwelling houses and in industry where a one-way water flow is required. Maximum operating pressure: Liquid temperature: 25 bar (PN 25).
3 Grundfos valves BV, MV 3/4" to 3" Dimensions and weights BV and MV valves are one-way valves with the valve casing made of cast iron or bronze. The valves have internal pipe thread and can be supplied with or without spring-loaded valve cone. BV: BVF: MV: MVF: foot valve without spring foot valve with spring non-return valve without spring non-return valve with spring. Applications BV and MV valves are used in minor water supply and pumping systems to avoid backflow when the pump is stopped.
BV, MV 4" to 6" Head loss without spring BV and MV valves are one-way valves with valve casing in stainless steel or nickel-resist alloy and other components in stainless steel. Foot valves (BV) in stainless steel are only available in the 6" dimension. BV 4" to 6" in nickel-resist alloy MV 4" to 6" in nickel-resist alloy BV 6" in stainless steel.
