Bright stem soft seal gate valve

Z41X-16QBright stem soft seal gate valveWorking Principle:

Rotate the handwheel to lift or lower the valve plate connected to the valve stem through the thread of the handwheel and valve stem, achieving the function of opening and closing.

According to the shell/Main material classification, gate valves can be divided into:

1. Metal material valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves, aluminum alloy valves, lead alloy valves, etc.

2. Metal valve body lined valves: such as rubber lined valves, fluorine lined valves, lead lined valves, plastic lined valves, and enamel lined valves.

3. Non metallic material valves: such as ceramic valves, glass valves, and plastic valves.

Z41X-16QBright stem soft seal gate valveIt has the following advantages:

1. Low flow resistance. The internal medium channel of the valve body is straight through, and the medium flows in a straight line with low flow resistance.

2. It is more effortless to open and close. Compared to globe valves, the direction of gate movement is perpendicular to the direction of medium flow, whether it is open or closed.

3. High height and long opening and closing time. The opening and closing stroke of the gate is relatively large, and the lowering is carried out through the screw.

4. Water hammer phenomenon is not easy to occur. The reason is that the shutdown time is long.

5. The medium can flow in any direction on both sides, making it easy to install. The two sides of the gate valve channel are symmetrical.

6. The structural length (the distance between the two connecting end faces of the shell) is relatively small.

7. The sealing surface is prone to wear and tear, which affects its service life. When opening and closing, the two sealing surfaces of the gate and valve seat rub and slide against each other, which is prone to abrasion and wear under the pressure of the medium, affecting the sealing performance and shortening the service life.

8. The price is relatively expensive. There are many contact sealing surfaces, and the processing is complex, especially the sealing surface on the gate seat is not easy to process, and there are many parts.

9. Simple form, short structural length, good manufacturing processability, and wide applicability.

Structural features:

For a long time, the general gate valves used in the market have generally suffered from water leakage or rusting. Our company has introduced European high-tech rubber and valve manufacturing technology to produce elastic seat seal gate valves, which overcome the defects of poor sealing and rusting of general gate valves. The elastic seat seal gate valve uses the compensating effect of slight elastic deformation generated by the elastic gate plate to achieve good sealing effect. This valve has significant advantages such as lightweight opening and closing, reliable sealing, good elastic memory, and service life.Z41XBright stem soft seal gate valveIt can be widely used as a regulating and intercepting device on pipelines such as tap water, sewage, construction, petroleum, chemical, food, medicine, textiles, electricity, ships, metallurgy, energy systems, etc.
