Ball Valves

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.

  1. Floating Ball Valves

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.

2.Fully Welded Ball Valves

Fully Welded Ball Valves are One of the most trusted valves in the petroleum industry and has the body fully welded by pipe materials. Fully welded ball valve combines the strength of forged steel components with a lightweight and compact spherical design. It is designed for district heating system , heat transfer piping , oil pipelines and gas industry application.

3.Meatal Seated  Ball Valves

Meatal Seated  Ball Valves are Suitable for abrasive or sticking fluids. It has Single direction seal,Low coefficient of friction, low torque. Metal seats can endure severe flashing, hydraulic shock, abrasive process fluid, and high temperatures up to and exceeding 1,000° F. They are also ideal for high erosion or corrosion applications.

4.Three-Way Ball Valves

3-way ball valves are used for dividing or mixing fluids and other special working media.including Full Bore and Reduced Bore 3-Way, 2-Seats, “L” Port Available with soft seats or metal seats. Each offers a range of performance suitable to many applications also 3-Way Top Entry, 4-Seats, “L” Port and “T” Port Used for diverting or mixing fluids.

If you need a 3 way ball valve, look no further. At Compressed Air Systems, we have valves in both T-flow and L-flow configurations, as well as in a range of sizes.Three- and four-way have an L- or T-shaped hole through the middle. The different combinations of flow are shown in the figure. It is easy to see that a T valve can connect any pair of ports, or all three, together, but the 45 degree position which might disconnect all three leaves no margin for error. The L valve can connect the center port to either side port, or disconnect all three, but it cannot connect the side ports together.

5.Trunnion Mounted Ball Valves

The Trunnion Mounted Ball Valves is a form of quarter-turn Valve which uses a hollow, perforated and fixed/supported 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.

SME Trunnion Mounted Ball Valves are widely used in oil and gas industries, industries of liquid gas,coal gas, etc.
