BNSV Swing Type Check Valve
Overview
Swing check valve is a valve that can automatically prevent fluid from flowing back. Valve disc is automatically opened under the action of fluid pressure, and fluid flows from the inlet side to the outlet side; when the pressure on the inlet side is lower than the pressure on the outlet side, the valve disc automatically closes under the action of the fluid pressure difference and own weight to prevent the fluid from flowing back . It is widely used in pipeline systems such as metallurgy, power stations, oil refineries and petrochemical plants.
1. It has an internationally single swing structure. The structure is simple with reliable action and wide application range.
2. It can be opened automatically by the pressure of the fluid.
3. Only applicable to unidirectional media.
4. The pin shaft is inside the valve body, so there is no need to drill holes on the valve body, which avoids water leakage in the later stage, and all fittings are matched.
