Cross-sectional View of Seat Supported Ball Valve with Ball and Seat DesignFunction

The Seat Supported Ball Valve is designed to provide reliable flow control in pipeline systems. The key feature of this valve is its seat-supported design, where the valve seat is placed in a way that it supports the ball, preventing excessive wear and ensuring reliable sealing even under high pressure or high-temperature conditions.

The ball valve design allows for full flow when the valve is fully open, minimizing pressure drop. When the valve is closed, the seat provides a tight seal that prevents leakage, ensuring fluid containment even under fluctuating operating conditions. The seat-supported design enhances valve performance by reducing the force required to operate the valve, making it ideal for automated systems that require high cycling frequencies.

Constructed from stainless steel, carbon steel, or alloy steel, the valve’s body and components are engineered to withstand harsh conditions, making it ideal for industries such as oil & gas, chemical processing, water treatment, and HVAC systems. The seat-supported design ensures that the valve can operate efficiently even under fluctuating pressures, providing reliable flow control in a wide range of applications.
