F5 Gate Valve-Soft Seal Gate Valve

Wedge gate valve disc can be made into a whole, called steel gate; It can also be made into a gate that can produce slight deformation to improve its technology and compensate for the deviation of sealing face Angle in the process of processing. This gate is called an elastic gate.

Soft seal gate valve is divided into open stem soft seal gate valve and dark stem soft seal gate valve two. Usually trapezoidal threads on the lifting rod convert the rotary motion into linear motion, that is, the operating torque into operating thrust, through the nut in the middle of the gate and through the guide slot in the valve body. When the valve is opened, the flow path is clear when the gate lift height is equal to 1:1 valve size, but this position cannot be monitored during operation. In actual use, the vertex of the stem as a mark, that is, the position of not moving, as its full open position. In order to consider the temperature changes occur locking phenomenon, usually open to the top position, and then rewind 1/2-1 turn, as the position of the fully open valve. Therefore, the full open position of the valve is determined by the position of the gate (i.e. stroke >. This type of valve in the pipeline should generally be installed horizontally.
