Salient Design Features and Benefits

1) Floating Design Concept

Our Floating ball design offers efficient sealing with simple construction. As the term indicates, the ball has slight freedom to move along the axis of the bore, connected pipeline, which offers efficient downstream sealing. when line pressure is applied to the closed ball, it moves slightly (or floats) downstream to maintain contact with the downstream seat where primary sealing occurs. A quarter turn motion from full open to full close ensures quick open-close action, an inherent advantage for automatic remote control application. Floating ball valve ensures effective bi-directional sealing.

2) Trunnion Mounted Design Concept

Trunnion mounted design offers precise locational accuracy for the ball within the upstream and downstream seat, which ensures leak tight sealing with lower operative torques. The sealing takes places by allowing the seats to move towards the ball. This design ball valves enables holding very high pressures.

3) Antistatic Design Feature

Antistatic design feature provision in our valves prevents any accidental fire due to static electric discharge, with the low resistance short circuit path created between the ball and valve body, any build up of static electric charge on the ball due to constant rubbing within the non metallic PTFE seat is prevented. The ball valve is completely conductive between ball and body in which no static electricity may develop. This is a requirement essential to the treatment of such low flashing point fluids as gasoline, natural liquefied gas, propane gas and others etc.

4) Fire-Safe

Valves exposed to risk of accidental external fire need to have additional secondary metal sealing system to make it fire safe. Special design features are built into the valve to ensure continued sealing performance even after burn out of the soft sealing parts of the valve. A metal seat located on the body comes in direct contact with the ball on burn out of the soft parts ensuring continued sealing. Our full range is approved as per the latest edition.
