High pressure cylinder valves with pneumatic actuator for corrosive gases – D156S
- 2-piece sturdy stem design in order to reduce particle generation.
- Non rotating lower spindle for increasing tightness during life time.
- No particle shedding threading in gas wetted areas.
- Self-adjusting compression of V-packings using disc springs, allowing a service temperature range from -40° to +65°C.
- Locking nut having left-hand thread that secures the valve mechanism, even if excessive torques are applied.
- O-rings fitted behind V-packings guarantee a secondary sealing, and they avoid the risk of humidity coming in contact with the gas wetted areas.
- Soft seat induces low operating torque.
- Soft seat is fixed with a special screw and its design improves the valve’s robustness against over torques.
