Dual Plate Wafer Check Valve, ASTM B148 C95800, 52IN

China Dual Plate Wafer Check Valve Factory Baltic Offers Wafer Type Dual Plate Check Valve:ASTM B148 C95800, 52 Inch, 150 LB, API 594, ASME B16.47B. Dual Plate Wafer Type Check Valve - bh-valveDual Plate Wafer Type Check Valve. 1. Small in size, light in weight, compact in structure,easy in maintenance. 2. Two torsion springs are used excreting on each of the pair valve plates,which close the plates quickly; And automatically. 3. The quick-close action prevents the medium from flowing back and eliminates water hammer effect. 4. Dual Plate Wafer Type Check Valve Manufacturers Product Description The dual plate check valves has two spring loaded half-moon shaped discs that rotate about their shaft. The disc plates are kept shut by the torsion spring. When fluid flows in the forwards direction, the pressure of the fluid causes the disc plates to hinge open, allowing flow.

The dual plate check valve is tested to API 598 which has a metal to metal seat permitted seal leakage of 3 cc/inch of bore/min. This small but significant amount arises because it is more difficult to obtain a perfect seal on a D shaped seat compared to a circular seat. Wafer Check Valve Swing Type to Mount Between FlangesMVS single plate swing type wafer check valve comes with a short pattern sandwich type flangeless wafer body conforming to the API 6D and ASME B 16.10 face to face dimensions. The valve has a simple but reliable and robust construction. The wafer check valve is ideal for pump discharge duties. The eccentric mounted hinge pin in combination with the disc seat guarantees a positive shut off of Wafer Type Double Disc Swing Check Valve , Stainless Steel Wafer Type Double Disc Swing Dual Plate Body Stainless Steel Check Valve . Check Valve Overview . Check Valves are automatic shut-off valves that are commonly used for preventing backflow or drainage in a pipe system.Often applied on the discharge side of pumps,check valves prevent the system from draining if the pump stops and protects against backflow, which could harm the pump
