Metal sealing Fixed ball valve Features:

1. Uses the spring pre-canada load the movable metal valve seat structure, can be suitable the high temperature, the high pressure as well as each medium pipeline.

2. The operation reduces effort: The medium pressure will produce the good action on the spheroid to transmit completely gives the lower bearing , the spheroid relative position migration ,the both sides valve seat seal stress will not be even , the operation moment of force will be low .

3. The enclosed seat structure is available for multiple designs subject to different working conditions.

4. The split seat design making its seal more reliable and maintenance more convenient; also available for providing an auxiliary sealant filler.

5. Its inlet and outlet are provided with double block and bleed function; light weight, compact structure and optional for either full or reduced bore.
