Castle wafer type check valves are utilized for pipelines to prevent backflow of the fluid. These mechanisms are fast acting thereby maximizing, In closing protection to hinder the adverse effect of the back, Flow. The procedure of opening and closing the valve takes place at an extremely low, Pressure difference over the valve disc. The connection of the eccentric disc shaft with the soft seat embedded inside the organism ensures a positive shut off of the returning medium. Salient features of castle wafer type check valves are wafer type check valve weighs much less when contrasted with the conventional flanged end swing check valves. Due to short overall length it has the potential to be easily installed in horizontal or in vertical pipeline without any special pipe support. The seat is integrated into the body with the goal of prevent contact with which results, The flow in longer life of the seat. Our wafer type check valve has minimum head loss due to large size of the orifice. The large orifice reduces head loose of the pump and thus saves energy. Short face, To, Face dimension of the valve makes it Quick to assemble between standard gaskets and line flanges.
