Din86251 Cast Iron Globe Valve

DIN86251 CAST IRON GLOBE VALVE 

[Working principle of stop valve]
Globe valve, also called cut-off valve, is the most widely used valve. The reason why it is so popular is that the friction between the sealing surfaces during the opening and closing process is small, it is relatively durable, the opening height is not large, it is easy to manufacture, and it is easy to maintain. Convenient and suitable not only for medium and low pressure, but also for high pressure. ​
The closing principle of the stop valve is to rely on the pressure of the valve rod to make the valve disc sealing surface and the valve seat sealing surface closely fit to prevent the flow of media. The stop valve only allows the medium to flow in one direction and is directional when installed. The structural length of the stop valve is larger than that of the gate valve, and at the same time, the fluid resistance is large, and the sealing reliability is not strong during normal operation.
