Z45X underground elastic seat sealing gate valve

Z45X underground elastic seat sealing gate valve, also known as lifting rod gate valve or rising stem gate valve. Usually, there are trapezoidal threads on the lifting rod, and through the nut on the valve top and the guide groove on the valve body, the rotational motion is converted into linear motion, that is, the operating torque is converted into operating thrust. When opening the valve, when the lifting height of the gate is equal to 1:1 times the valve diameter, there is no obstruction to the fluid channel, but this position cannot be monitored during operation. In actual use, the vertex of the valve stem is used as a marker, that is, the position where it cannot be opened, as its fully open position. To consider the phenomenon of locking due to temperature changes, it is usually done by opening the valve to the top position and then reversing it back, 1/2-1 turn, as the position for fully opening the valve. Therefore, the fully open position of the valve is determined by the position of the gate (i.e. stroke).

Z45X underground elastic seat seal gate valve is a replacement product of traditional gate valves, which uses the compensating effect of slight deformation generated by the elastic gate plate to achieve good sealing effect. This underground elastic seat seal gate valve has significant advantages such as light opening and closing, sealing, good elastic memory, and long service life.

Z45X underground elastic seat seal gate valve can be widely used as a regulating and shut-off device on fluid pipelines such as tap water, sewage, construction, food, electricity, medicine, metallurgy, textile, energy systems, etc.
