Spring loaded dual port cylinder valve for corrosive gases – D195S

High pressure cylinder valve - Dual Port - Spring loaded gland packing - soft seat

Key advantages

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.
