The VSAN Ball Valve is a high-performance quarter-turn isolation valve designed for reliable shut-off and efficient flow control of liquids, gases, steam, and various industrial process media. Engineered with precision and manufactured using premium-quality materials, the valve offers excellent sealing performance, low operating torque, and long service life, making it an ideal choice for demanding industrial applications.
The valve consists of a precision-machined spherical ball with a full-bore or reduced-bore opening. By rotating the ball through 90 degrees, the valve quickly changes from a fully open position to a completely closed position, providing fast and reliable isolation. The simple operating mechanism ensures smooth operation, minimal maintenance, and excellent durability even under continuous service conditions.
The VSAN Ball Valve is manufactured from high-grade materials including Stainless Steel (SS304, SS316, SS316L), Carbon Steel (WCB), Forged Steel, Brass, Bronze, Duplex Stainless Steel, and other special alloys to suit a wide range of industrial applications. Various seat materials such as PTFE, Reinforced PTFE (RPTFE), PEEK, Nylon, Delrin, Viton, and Metal Seats are available to meet different temperature, pressure, and chemical compatibility requirements.
The valve is available in multiple configurations including Two-Piece, Three-Piece, One-Piece, Floating Ball, Trunnion Mounted Ball Valve, Full Port, Reduced Port, Flanged, Threaded, Socket Weld, and Butt Weld End Connections. It can be operated manually using a lever or gear operator, or automatically through Pneumatic, Electric, and Hydraulic Actuators, making it suitable for both manual and automated process control systems.
Designed in accordance with international standards such as API 6D, API 608, API 598, ASME B16.34, ISO 17292, BS EN 1983, and ISO 5211, the VSAN Ball Valve ensures reliable operation under high-pressure and high-temperature process conditions. The valve is available in pressure ratings ranging from PN10 to PN40, ANSI Class 150, 300, 600, and higher depending on application requirements.
The valve supports optional accessories such as limit switches, solenoid valves, position indicators, electro-pneumatic positioners, lockable handles, and smart valve controllers, enabling seamless integration with PLC, DCS, SCADA, and Industrial Automation Systems.
With its bubble-tight shut-off, low pressure drop, corrosion-resistant construction, and compact design, the VSAN Ball Valve is widely used in Oil & Gas, Chemical Processing, Petrochemical Industries, Water Treatment Plants, Pharmaceutical Manufacturing, Food & Beverage Industries, Power Plants, Marine Applications, Steel Plants, HVAC Systems, Mining, and Industrial Utility Networks.
The VSAN Ball Valve provides dependable flow isolation, superior sealing performance, and reliable long-term operation, making it one of the most versatile valves for industrial fluid handling applications.
The VSAN Ball Valve operates on the Quarter-Turn Rotary Ball Principle.
Inside the valve body, a precision-machined spherical ball with a central bore is mounted between two valve seats. When the operating handle or actuator is rotated through 90 degrees, the ball rotates simultaneously.
When the bore of the ball is aligned with the pipeline, the valve is fully open, allowing unrestricted flow with minimal pressure loss. When the handle is rotated by 90 degrees, the solid portion of the ball blocks the flow path, creating a tight and reliable seal that completely stops the flow of the process medium.
The resilient or metal seats provide excellent sealing around the ball, ensuring bubble-tight shut-off even after repeated operation. Automated versions utilize pneumatic, electric, or hydraulic actuators to enable remote operation and integration into industrial automation systems.
The simple quarter-turn design allows for quick operation, low operating torque, and dependable performance, making the ball valve ideal for both isolation and process control applications.
The VSAN Ball Valve is extensively used for flow isolation and process control across various industrial sectors.
