BNSV Rising stem gate valve


Turn the hand wheel to lift or lower the valve plate connected with the valve stem through the advance and retreat of the thread between the hand wheel and the valve stem, so as to achieve the function of opening and closing. The opening and closing part of rising stem gate valve is the gate, and the movement direction of the gate is perpendicular to the flow direction. The rising stem gate valve can only be fully opened and fully closed, and can not be adjusted and throttled.

● It is easy to open and close.

● The flow direction of the medium is not limited, the flow is not disturbed and the pressure is not reduced.

● It has the advantages of simple shape, short structure length, good manufacturing process and wide application range.
