Ball Valve

A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it.Ball valves are broadly used in industry due to its reliability, easy operation and wide range. A valve with a Center bored ball just by operating it between 90° make it a On-Off Valve. The bore allows the fluid to pass through once its in sequence to ports.

The Trunnion Mounted Ball Valves is a form of quarter-turn Valve which uses a hollow, perforated and fixed ball to control flow through it. Trunnion Mounted ball valves offer lower torque than floating ball valves and offer more consistent service over time, but are more complex and hence require a more expensive maintenance routine than standard ball valves. Trunnion Mounted Ball Valves are widely used in oil and gas industries, industries of liquid gas,coal gas, etc.

Floating ball valves are usually considered to be a simple type of valve.when it comes to tightness, floating ball valves are more reliable than trunnion ball valves. The reason is that in floating ball valves, unlike in trunnion ball valves, the system pressure forces the entire ball against the downstream seat. In trunnion ball valves the pressure usually force the upstream seat against the ball and hence they depend on seats that can be locked in the seat pocket due to various impurities.
Floating Ball Valves are mainely used in oil and gas products, chemical industry, metallurgy, construction etc.
