Feature:
1. The product has reasonable structure, reliable sealing, excellent performance and beautiful
appearance.
2. Its sealing is realized by the sealing face around the sleeve. It has unique 360 degree metal
edge for protection and fixing of the sleeve.
3. There Is no cavity in the valve for accumulation of medium.
4. Metal edge provides the function of self-cleaning when the plug is rotated,
applicable to the operation condition that is glutinous and apt to smudge.
5. Its characteristic double-direction flow makes installation and sue more convenient.
6. The materials of the parts and sizes of flanges can be reasonably configured according
the actual operation condition of the requirements of the customers, so as to meet
the various needs of engineering.
