Advantages & Features
- Hardening of the sealing surface；
- Full-through bore, Low flow resistance；
- Anti-dust and anti-accumulation, long life ；
- Flowway hardened,anti-scouring.
Working Principle
The 90-degree angular stroke opens and closes, and the opening and closing is rapid; theFull-through bore has strong flow capacity; the special hardening process makes the sealing surface stable and reliable for a long time; the spring cavity dust-proof design extends the valve life and maintenance-free operation time.
