Anti-Static Device & Blowout Proof
Anti-static device is formed through metal to metal contact, The stem is grounded against body and ball by separate anti-static spring to avoid from any electric spark. The blow out proof over size stem operate the valve safety even at high differential pressure. A bottom stem seal enabling replacement of gland packing even when valve may under pressure.

Double Block & Bleed
Spring loaded floating seats maintain contact with the ball and provide tight shut off even at low pressure differential. Independent sealing of upstream and downstream sides facilitates draining of fluid from the body cavity, and thus the double block and bleed operation.

Double Body Sealing
Double seal combination of O-Ring and spiral wound gasket ensures perfect body joint sealing. Reliable Valves therefore meet or exceed the fugitive emission requirements across wide range of pressure and temperature applications. Valves are suitable for both above and underground installations.

Multiple Stem Sealing
A triple sealing arrangement in stem area prevents leakage to atmosphere. It includes double sealing with O-rings and graphite seal at the top of stem housing. The blow out of proof stem enables positive stem retention.

Sealant System & Lubricant
Ball valve of size 6” & above shall be provided and emergency sealant injection system if required by customer. The lubricant & sealant fittings are located near seat area & at stem neck. The lubricant sealant entered via inject fitting & pass around the seat ring. The lubricant will lower the torque in valve & sealant will provide sealing for minor damage such as scratches on seal faces.

Fire Safe Design
In the event the fire soft insert gets burnt & spring loaded seats ensure metal to metal sealing.

Corrosion Protection & Painting
All castings are sand blasted & are subject to dewatering oil coats. Valves are thoroughly cleaned & primer coated with epoxy zinc phosphate primer, Followed by final coat of epoxy synthetic enamel applied in semi gloss finish.
