Globe valve, also known as stop valve, is one of the most widely used one of the valves. it is popular, because the opening and closing process between the sealing surface friction is small, more durable, open height is not easy to manufacture , Easy maintenance, not only for low pressure, but also for high pressure.
The closing principle of the globe valve is to rely on the pressure of the valve, so that the valve sealing surface and the valve seat sealing surface close to prevent the media circulation. Globe valve' structure length is greater than the gate valve, while the fluid resistance, long-term operation, the sealing reliability is not strong.
The sealing seal of the globe valve is composed of a sealing surface of the valve disc and a sealing surface of the valve seat. The valve stem drives the valve plate to move vertically along the center line of the valve seat. Closing valve opening and closing process in the opening height is small, easy to adjust the flow, and easy manufacturing and maintenance, pressure for a wide range.
