Square Hygienic Flange Ball Valve

Three-way ball valves are primarily used to switch flow paths while cutting off or connecting media. The square three-way ball valve features an widened contact surface between the body seal ring and the ball, avoiding the small contact area of standard three-way ball valve body seals. Combined with the lack of positioning design in standard three-way ball valves, when the valve is opened/closed, the ball shifts from the sealing surface, causing incomplete closure and internal leakage. If cost is not the primary concern, square three-way ball valves are one of the optimal choices for three-way process pipelines.
