Common types and characteristics of hydraulic valves
2025-09-25
Gate valve: The opening and closing component is a gate valve, which controls fluid flow through vertical lifting and lowering. It has the characteristics of low fluid resistance and good sealing, and is suitable for fully open or fully closed situations, such as reservoirs, pump stations, and pipeline systems. But the opening and closing speed is slow and not suitable for flow regulation.
Globe valve: By rotating the valve stem to drive the valve disc up and down, the flow control performance is better than that of gate valves, but the switching action is slower. Commonly used in scenarios that require precise flow control, such as regulating valves in water treatment plants and pipeline systems.
Ball valve: The opening and closing components are spherical, which can be quickly opened and closed by rotating 90 degrees. It has the advantages of simple structure, easy operation, and good sealing, and is suitable for occasions that require rapid cutting or distribution of media, such as water pump inlet and outlet control.
Butterfly valve: The opening and closing components are butterfly plates, which control fluid flow through rotation. It has the characteristics of small size, light weight, and fast switching, and is suitable for large-diameter pipeline systems such as water treatment plants and water pipelines.
Check valve: automatically opens and closes by relying on the flow of the medium to prevent backflow. Common types include lift, swing, and spring, which are suitable for protecting pump systems from reverse flow damage.
Regulating valve: It is commonly used in the field of industrial automation process control to adjust parameters such as medium flow rate and pressure by receiving control signals.
Multi functional hydraulic valve: integrates multiple functions such as voltage stabilization, pressure relief, flow control, etc., suitable for complex hydraulic systems. For example, the JD745X multifunctional water pump control valve adopts a ductile iron diaphragm piston structure, which can achieve functions such as voltage stabilization and waterproof hammer.
