Working Principle: Controls the on-off of fluid through the vertical lifting of the gate along the axis of the valve seat. When fully open, the water flow resistance is small; when fully closed, the sealing surface can prevent the medium from flowing.
Application Range: Commonly used in water supply and drainage pipelines, heating systems, long-distance oil and gas pipelines, etc. It is suitable for scenarios requiring full opening or full closing, and not suitable for flow regulation.
Performance Characteristics:
- Good sealing performance and low fluid resistance.
- Long opening and closing stroke, large operating torque, and long opening and closing time.
- The valve body structure is relatively complex, with large size and weight.
