Ball Valve Manufacturer in India
Speciality Valve is a Ball Valve Manufacturer in India offering high-performance quarter-turn valves for reliable isolation in oil & gas, power, water, chemical, and marine applications. Our valves are designed for low pressure drop, tight shut-off, and long service life in demanding service conditions.
Function & Working
Ball valves use a perforated spherical ball that rotates 90° to open or close the flow path. Full-bore options minimize pressure loss; reduced-bore designs balance cost and Cv. Available in floating and trunnion-mounted constructions for the right mix of torque, sealing, and pressure capability.
Advantages
Fast quarter-turn operation
Low pressure drop; high Cv
Fire-safe and anti-static options
Suitable for severe service and high differential pressure
Easy inline maintenance (top-entry/3-piece options)
