Ball Valve

Ball Valve Supplier in Dubai — Isolation and Flow Control for Every Application

Ball valves are quarter-turn shut-off valves designed to start, stop, and regulate flow using a rotating spherical disc. The valve opens when the port in the ball aligns with the pipeline and closes when the ball is turned 90 degrees. Their simple mechanism, compact construction, and minimal pressure drop make ball valves widely used across oil & gas, chemical plants, power stations, water treatment systems, marine operations, and general industrial process applications.

What Is a Ball Valve?

A ball valve is a mechanical device consisting of a metal or alloy body, a floating or trunnion-mounted ball, PTFE/metallic seats, stem, and end connections. It allows quick isolation through a quarter-turn rotation. Ball valves offer full-bore or reduced-bore options, low torque operation, and compatibility with manual, pneumatic, electric, and hydraulic actuators.

How Ball Valves Work?

1)The ball has a central passage (port).
2)When the handle or actuator rotates the ball by 90°, the port aligns with the flow path, allowing fluid to pass.
3)Turning the ball again blocks the passage, creating shut-off.
4)Seats positioned around the ball ensure tight sealing.
5)Trunnion-mounted designs use fixed bearings for higher pressure applications.

This straightforward mechanism allows consistent operation in gases, liquids, steam, and abrasive media, depending on material selection.

Ball Valve Benefits:

1)Quarter-turn operation for fast opening and closing
2)Minimal pressure drop across the valve
3)Suitable for automation (ISO 5211 mounting pad)
4)Tight sealing performance
5)Adaptable to high-pressure and high-temperature conditions
6)Wide choice of body, seat, and trim materials
7)Applicable to clean, corrosive, and erosive fluids depending on configuration
