Double Disc Wafer Check Valves
As one of the leading double disc wafer check valves manufacturers and suppliers in China and equipped with a productive factory,Website:, Shanghai Hugo Valve Co.,Ltd is always at your service.Double disc wafer check valves Description1. Comparing with flanged swing check valve, double disc wafer check valve have small water hammer pressure, because the spring assisted closure, it's easy to close the wafer type double disc swing check valve.2. Wafer double disc check valves have short length of face to face, low volume and light weight comparing with flange type swing check valve, which gives a vast convenient for installation, portage,storage and pipeline arrangement, moreover reduced raw material cost.3. There is small fluid resistance for wafer type dual plate swing check valves, the fluid resistance coefficient ? is 2.6to 0.7, when the valve's size is becoming more bigger, the flow resistance coefficient is more smaller.4. The installation direction can be in horizontal or vertical, as the valve weight is light, not necessary to make bracket for the valve body.5. There is small opening pressure for double disc no-return swing check valves, the disc can be fully opened under the condition of small differential pressure.6. There are several connection end for double disc swing check valve, such as wafer type, lug type valves materials of constructionBody Materials: LCB,LCC,WCB, 304S.S., 316 S.S.Spring Materials: LCB,LCC,WCB, 304S.S., 316 S.S.Disc Materials: LCB / LCC / WCB + stellite, 304S.S., 316 S.S.
