In the vast majority of water treatment systems and industrial automation control applications, motorized ball valves offer distinct overall advantages over gate valves. This is particularly true in small-diameter pipelines and scenarios requiring rapid opening and closing.
This article details the advantages of motorized ball valves over motorized gate valves.
1.Operating speed and switching time
Motorised ball valves feature extremely fast switching speeds, with the valve core requiring only a 90-degree rotation to reach the fully open or fully closed position, making them particularly suitable for applications demanding rapid operation. In contrast, motorised gate valves require multiple rotations of the valve stem to lower the gate, resulting in significantly longer switching times compared to motorized ball valves.
2. Sealing Performance
Motorised ball valves offer exceptional sealing performance, with their soft-seal design ensuring zero leakage. In contrast, motorised gate valves employ a sliding seal mechanism, resulting in inferior sealing capabilities that make achieving zero leakage extremely difficult.
3. Required installation space
Motorised ball valves boast a more compact design with a smaller footprint, offering significant advantages in confined pipework or automated equipment. In contrast, motorised gate valves feature a greater overall length and heavier weight, necessitating more substantial installation space.
4. Easier to maintain
Motorised ball valves exhibit minimal wear during operation, require simpler maintenance, and boast a longer service life. Jinfeng Valve's motorised ball valves can withstand over 100,000 opening and closing cycles. In contrast, motorised gate valves experience friction between the disc and seat during operation, leading to greater susceptibility to wear and relatively more complex maintenance requirements.
5.Intelligence and adaptability
Motorised ball valves can be employed both to shut off flow and to regulate flow rate through angular adjustment. Motorised gate valves, however, cannot be used for flow regulation. When not fully open or fully closed, water flow will impact the gate plate, causing the valve to fail.
Summary:
Applications requiring motorised ball valves:
Situations demanding stringent sealing performance
Applications requiring rapid opening, closing and operation
Applications with limited installation space or weight constraints
Situations requiring precise flow control
Applications requiring swing gate valves:
Situations requiring substantial flow capacity with less stringent sealing requirements
Applications where frequent operation is unnecessary and long-term operation in the fully open position is feasible
In modern automated industrial or water treatment equipment, motorised ball valves have become the preferred choice for an increasing number of projects.
