- Product Description
-
Jacketed insulated check valves are mainly used in various systems such as petroleum, chemical, metallurgical, and pharmaceutical industries to transport high-viscosity media that solidify at room temperature. The jacket of this series of valves is welded between the two flanges of the valve, and the connection ports for the jacket heating medium are set on the side and bottom of the valve. Due to the added jacket, the connection flange size of this type of valve is one to two specifications larger than that of a conventional check valve of the same specification, but the structural length is the same as that of the valve of the same specification. Steam or heat transfer oil medium can flow freely in the jacket to ensure that the viscous medium can flow smoothly through the valve.Valve body material: Stainless steel (316L, 304, CF3M, CF8), Duplex steel, Carbon steel, TitaniumConnection type: FlangedStandards
