Valve Characters
- Y-Type forged valve body, low flow resistance, greater Cv value
- Disc with throttle piece, effectively protect sealing surface, extend valve service life.
- Disc & Seat sealing surface through special craft processing and machining, anti-cavitation, erosion-resistant.
- Processing two guide rings in disc, stem suffer force balanced, flexible movement.
- Stem packing all of imported U.S. Garlock high-quality flexible graphite packing, good chemical properties and flexibility, low friction, long service life.
- Fast switching-speed, normally 3-5 seconds, effective protection of system security, greatly reducing the time of the sealing surface erosion by media.
- There are disperse heat disks in the bonnet, can fully heat dissipation which protects pneumatic actuator & accessories are not subjected to high temperature and failure. Chamber gasket is clip S.S. wire high mesh flexible graphite with a better sealing and reliability than general type
