German Standard F4 Soft Sealed Gate Valve

Short Description:

The gate has two sealing surfaces. The two sealing surfaces of the most commonly used mode gate valves form wedges. The wedge angle varies with the valve parameters, usually 50. When the medium temperature is not high, it is 2 52. Wedge gate valve can be made into a whole, called rigid gate; it can also be made into a gate that can produce slight deformation to improve its workability, make up for the deviation of sealing surface angle in the process of processing. This kind of gate is called elastic gate.

Usually there are trapezoidal threads on the lifting rod. Through the nut at the top of the valve and the guide groove on the valve body, the rotary motion is changed into linear motion, that is to say, the operating torque is changed into the operating thrust. When opening the valve, when the gate lifting height is equal to 1:1 times the valve diameter, the flow passage is completely open, but when running, this position can not be monitored. In practical use, the vertex of the valve stem is used as the sign, that is, the position of the valve stem that is not moving is used as its full open position. In order to consider the locking phenomenon of temperature change, the valve is usually opened to the vertex position and reversed to 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).

Product characteristics:

1. Flat-bottomed seat, no accumulation of dirt, make the seal more reliable.

2. The valve disc is encapsulated with NBR as a whole. The inner parts of the valve are made of corrosion-resistant stainless steel and copper alloy, which can be used for sewage system to adapt to harsh working conditions.

3. Small size, light weight, easy to install and maintain

4. The valve stem is sealed with three O-rings, which greatly reduces the friction resistance of the switch and makes the switch light and water-tight.
