Gate valve is a widely used valve, which is sealed by contacting the valve seat and gate. Usually, the sealing surface will be overlaid with metal materials to increase wear resistance.It can only be fully opened and closed, not adjusted or throttled.

There are rigid gate and elastic gate, according to the different gate, gate valve is divided into rigid gate valve and elastic gate valve.

1.Precision casting valve body, refined appearance

The valve body is made of WCB material,the internal part numerical control lathe machining.

2.Valve seats wear better

The seat adopts Cr stainless steel and surfacing 507 molybdenum to increase the wear resistance of the seat.

3.bonnet of valve stem inverted seal disposal to prevent leakage.

Do inverted seal on the contact between cover and stem to prevent leakage.

4.Pressure test of valve stem before delivery.

Each valve must do double pressure test of valve body and seal according to strict standard.

5.Carry out quality inspection for many times and ensure quality.

Strict quality inspection is carried out in every link from parts to finished product packaging.

Inventory and Quality Control

Why do valves always fail?

In the whole process of design,manufacture, installation,working condition,operation and maintenance,every step should not be lax.

The valve inspection process is as follows:

1:Appearance inspection:

(1)Whether there are sand holes, cracks and other defects on the inner and outer surface of the valve body;

(2)Whether all parts of the valve are damaged, whether the valve body is marked, etc;

2:Performance test

3.Shell strength test

4.Sealing test

5.Action performance test

6.Vacuum sealing test
