What are the types of hydraulic quick connectors?

Hydraulic quick connector is a device used to quickly connect and disconnect hydraulic system pipelines. They can greatly increase the productivity and safety of the system. Due to the wide range of applications in the hydraulic field, there are also different types of quick couplings.

Straight-through type: Since there is no one-way valve in this connection system, it can achieve a very large flow rate, while avoiding the flow change caused by the valve. When the medium is a fluid, such as water, straight-through couplings are ideal. When disconnecting, intermediate fluid transfer must be stopped beforehand

Single-closed type: single-closed quick-change joint, the plug body is a straight-through type; when the connection is disconnected, the one-way valve in the joint body is immediately closed, which effectively prevents fluid leakage. Single Closed Quick Couplings Ideal for Compressed Air Equipment

Double-closed type: When the double-closed quick-change joint is disconnected, the one-way valves at both ends of the joint are closed at the same time, while the medium remains in the pipeline and maintains the original pressure

Safe and non-leakage type: Both the joint body and the valve in the plug body are flush with the end face, with a very small residual dead angle. This ensures that no medium leaks out when the connection is disconnected. This design is especially suitable for corrosive media or sensitive environments, such as clean rooms, chemical plants, etc.

In short, factors such as working pressure, temperature, sealing performance and connection strength should be considered when selecting hydraulic quick connectors. Proper selection and use of hydraulic quick connectors will ensure the reliability and safety of the system.
