Design options of Straight-though Ball Valve PN 8
Main design features and advantages
- Application of self-positioned plug as well as Teflon sealing of stuffing box, body-to-plug and body-to-flange joints provides simplification of valve design and ensures valve reliability.
- Stem is tightly sealed from ambient and body-to-plug joint as well as body-to-flange joint with Teflon sealing rings.
- Full cycle of test guarantees in any case leak-proof operation of the valve.
- Valves need no servicing (designed for long-term operation).
