 Worm gear all welded ball valve (DN 15-1000)

All welded ball valve texture of material:

1) : valve body: carbon steel st37.0, a106-b; 20 steel

2) : Ball: stainless steel 304 or 316

3) : stem: 2Cr13

4) : stem seal: Perfluorocarbon

5) : ball seal: rtfe (PTFE + C)

Standard features of all welded ball valves:

1) : diameter: DN 15 ~ 1000

2) : pressure: PN 16 ~ 40

3) : working temperature: - 29 ℃ ~ + 200 ℃

4) Suitable medium for welding ball valve of gas transmission pipeline: Petroleum / gasoline, liquefied natural gas / liquefied petroleum gas, petrochemical industry, steel plant, heating pipeline, etc

5) : gas pipeline welding ball valve operation mode: handle, gear (vertical / horizontal), electric, turbine

Application of all welded ball valve:

1) : City gas: gas output pipeline, trunk line and branch supply pipeline, etc.

2) Central heating: output pipeline, trunk line and branch line of large heating equipment.

3) : heat exchanger: opening and closing of pipes and circuits.

4) Iron and steel plant: all kinds of fluid pipeline, waste gas selective discharge pipeline, gas and heat supply pipeline, fuel supply pipeline.

5) : various industrial equipment, various heat treatment pipelines, various industrial gas and heat pipes.

Performance of all welded ball valve:

1) No need of maintenance, adjustment and lubrication, easy installation, long-term reliable operation at low operating cost. The surface adopts spray plastic treatment technology, with beautiful luster, which has been in the forefront level in China. There will be no external leakage. The valve body is of welded construction, so the valve is light and easy to insulate. It is very simple to install the adjusting mechanism. The operating handle can be removed and installed in reverse direction.

2) : since the valve seat is composed of carbon fiber reinforced Teflon sealing ring and disc spring, it has strong adaptability to the change of pressure and temperature, and there will be no sliding within the marked pressure and temperature range.

3) : the machining process of the sphere is tracked and detected by advanced computer detector, so the machining accuracy of the sphere is high.

4) : as the valve body material is the same as the pipe material, it will not cause uneven stress and deformation due to earthquake and vehicle passing through the ground, so the pipeline is aging resistant.

5) : integral full welding, equal diameter and variable diameter channel, fixed ball and floating ball, double piston effect sealing system, automatic

Injection sealant type bearing.

6) : in order to prevent static electricity, steel balls and springs are respectively installed between the valve stem and the ball and between the valve stem and the packing box, which can keep the electric conduction between all parts of the valve and the valve body, and let the current pass through the area to release static electricity. In order to prevent the fire, not only to prevent the fire, but also to prevent the fire.

7) : the valve stem anti dropping function is because the valve stem is affected by the pressure in the valve, and the total force is generated, so the valve rod is designed as an anti dropping structure.

8) : push the pressure to the valve stem with thrust washer support of low friction material, so that the valve stem only serves to transmit torque.
