Fitur

Zero inline leakage : 480 to 600 % higher sealing area.

Class VI bubble tight shut off : burnished piston sealing.

Zero gland leakage : No gland packing.

Soft seated Sealing : Stainless steel reinforced graphite piston rings.
Perfect interface fit : Positive sealing effect and burnished piston.

Interchangeability of parts : Universal sealing rings. No special
adaptation for spare parts.

No water hammer : The lantern bush cage guides the piston movement.
Variable orifice created by the lantern bush and piston eliminates sudden
shocks and water hammer.

In-line maintenance : Critical components can be replaced without
removal of valve from line.

No wire drawing : The valve seating is on the sides which eliminates the
possibility of wire drawing effect

Protection of wetted parts : In open and closed condition, piston
remains enclosed in sealing rings and is hence protected from erosive or
corrosive material.
