Flange gate valve and flange ball valve differences
This article analyzes the core difference between flange gate valve and flange ball valve: structurally, the gate valve adopts the design of up and down movement of the gate plate (composed of the valve body, bonnet, etc.), while the ball valve is operated by rotating the ball by 90 degrees (including the valve body, ball, etc.); on the working principle, the gate valve relies on the sealing of the valve seat by the gate plate fitting, while the ball valve achieves the circulation through the rotation of the ball; on the usage scenario, the gate valve is suitable for the completely open and close and leakage prevention of strict occasions (e.g., water In terms of usage scenarios, gate valves are suitable for fully opening and closing and for strict leakage prevention (e.g. water treatment facilities), while ball valves are suitable for quick operation (e.g. fire protection systems). It is important to choose the right valve according to the actual needs and fluid characteristics.
