Double release direct buried all welded ball valve, gas all welded ball valve 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: perfluoro rubber

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


Double release direct buried all welded ball valve, features of all welded ball valve for gas:

1): diameter: DN15 ~ 300

2): pressure: PN 16 ~ 40

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

4): directly buried welding ball valve suitable media: Petroleum / gasoline, liquefied natural gas / liquefied petroleum gas, petrochemical industry, steel plant, heating pipeline, etc.

5): direct buried welding ball valve operation mode: handle, gear (vertical / horizontal), electric


Double release direct buried all welded ball valve, all welded ball valve for gas features:

1): direct buried welded ball valve, no external leakage, etc.

2): as the valve seat of direct buried welded ball valve is composed of carbon Teflon sealing ring and coffee spring, it has strong adaptability to the change of pressure and temperature, and will not produce any leakage within the range of pressure and temperature indicated.

3): the machining process of directly buried ball valve ball has advanced computer detector tracking detection, so the machining accuracy of the ball is high.

4): as the valve body material is the same as the pipe material, the direct buried welded ball valve will not have uneven stress, and will not have deformation due to the earthquake and when the vehicle passes the ground. The pipe is resistant to aging.

5): the seal ring body is made of PTFE with 20% C (carbon) content to ensure no leakage (0%).

6): the directly buried welded ball valve can be directly buried in the ground, without the need to build high and large valve wells, and only need to set up small shallow wells on the ground, greatly saving construction costs and project time.

7): the length of the valve body and the height of the valve rod can be adjusted according to the construction and design requirements of the pipeline.

8): the machining accuracy of the sphere is very precise, the operation is light, and there is no bad interference.

9): the raw material of * * * is used to ensure the pressure above PN25.

10): compared with the same specification products of the same industry, the valve body is small and beautiful.

11): under the condition of ensuring normal operation and use of the valve, the direct buried welded ball valve shall be guaranteed for 20 years.
