Inner Dual Plate Check Valve
Product Description KOSEN Inner Dual Plate Check Valves are suitable for using on various kinds of pipeline from Class150 To Class2500, PN20 To PN420 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil,...
The Inner Dual Plate Check Valve is a thin spring-assisted closing check valve. It consists of a ring-shaped valve body and a valve plate. The valve plate can be opened and closed by swinging around the rotating shaft. The machining groove is located on the upper part of the rotating shaft. The fixed shaft with a torsion spring is fixed by fastener. The extension part of the torsion spring is pressed on the valve plate and applied to the valve plate. The utility model processes a groove on the valve body, sets the torsion spring sleeve on the fixed shaft, and fixes the fixed shaft in the groove through a fastener.
