It is applicable to urban gas pipelines, large heating equipment pipelines, and various fluid, gas and heat supply, fuel supply pipelines of steel plants.

The valve body is formed from steel plates and assembled and welded as a whole to avoid any possible leakage of media. The spring loaded valve seat combination structure is adopted, which has strong adaptability to pressure and temperature changes to ensure the close contact between the seal ring and the ball. On the premise of ensuring the seal, the valve can be opened and closed flexibly and operated easily. The ball and the valve stem are processed by precision machine tools, reducing the friction coefficient between the contact surfaces, The sealing performance and operating torque of the valve are further improved.

1. Leading technology in China, maintenance free and long service life.

2. The welding process is unique, with primary air hole, no sand hole, high pressure bearing, and zero leakage of valve body.

3. It adopts high-quality stainless steel ball and double-layer supporting sealing structure. The ball support is scientific and reasonable.

4. The sealing gasket is made of Teflon, nickel, graphite and other materials and is carbonized.

5. The valve well has low cost and is easy to open.

6. The valve body length of directly buried welded ball valve can be determined according to the buried depth.

7. A non-return valve type grease injection port which can also prevent the backflow of lubricating sealant under high pressure is provided.

8. According to the needs of the medium in the pipeline system, the valve is equipped with a blow off, blow down and prevention device.

9. CNC production equipment, strong technical support, reasonable software and hardware collocation.
