Notes: Serial valve connecting flange and butt-welding terminal size can be designed at customers'request. The material of the main parts and sealing surface of the valve can be designed and selected according to the actual working conditions or the special requirements of users.

 

 

1. The gate plate of the valve with a diversion hole, whether fully opened or fully closed, is always consistent with the sealing surface, and the sealing surface is protected from direct erosion by the medium, thereby extending the service life.

2. When fully opened, the channel is smooth and straight, the flow resistance coefficient is minimal, there is no pressure loss, and the pipeline can be cleaned with hairball.

3. The packing structure with self-sealing ability is adopted, without frequent adjustment.

4. The sealing structure of the seat should be elastic with pre-loading force, and the upper and downstream sealing seats should be sealed at the same time. The seat and seal are always sealed face to face.

5. The seat has a self-cleaning function, and is not directly washed by air flow during the opening or closing of the valve. The seat shall be made of lubricated, non-abrasive material.

Q: There are several sealing pairs of valves, whether they are inlet seals or outlet seals?

A: The disadvantage is that the sealing pair has two sealing surfaces, and the conventional is the exit seal.

 

Q: When the valve is closed, can it automatically remove the high pressure in the inner cavity?

A: When the valve is closed, the high pressure in the inner cavity can be automatically removed to ensure the safety of use.

 

Q: Can it be used all day?

A: Fully enclosed structure, good protection performance, can adapt to all-weather requirements.

 

Q: There is no stroke indication of the valve?

A: The valve is provided with an indicator rod or an observation window to indicate the opening and closing of the valve.

 

Q: What is the concept of antistatic?

A: Ensure the electrical conductivity between the internals and the outside world, especially the ball valve to ensure the conduction between the ball stem, to prevent the friction between the ball and the seal from generating static electricity and fire.

 

Q: The preferred material of oxygen valve is copper, why?

A: Copper material has good flame retardant properties.

 

Q: When the flange connection is convex and concave, if not specified, then the valve flange end should be concave or coated?

A: Concave

 

Q: According to ANSI B 16.10, the structural length of RTJ flanged valve is longer, how to add it?

A: The structural length of the convex flange valve plus the structural length specified in the table constitutes the end length of the ring connection.
