How Is The Stop Valve Used?

The stop valve is used to close, open and throttle the pipeline medium. The stop valve can completely block the fluid and form a good seal under the force of the valve stem; the Y-type stop valve is determined according to the overall design and installation requirements of the valve; the stop check valve is In the open state, it can be used as a component to control the one-way flow of the pipeline medium. When the medium flows forward, the valve is opened by the pressure of the pipeline itself. When the medium flows backward, the weight of the valve disc and the backflow pressure of the medium act on the back of the valve disc, causing the valve to open. The disc and the valve seat form a seal to achieve the purpose of non-return and interception. From the 10% open position to the full open position, the stop valve with a throttling disc is effective in regulating the flow of the pipeline.

This type of valve rotates the handwheel clockwise, and the valve disc descends until the channel is completely cut off and the valve is closed. Rotate the handwheel counterclockwise, the valve disc will rise until it hits the obstruction, and the valve will open. For electric device valves, a backup handwheel can be used to open and close the valve in emergency situations such as power outage.
