FK-C1 Ball Valves Type Hydraulic Quick Coupling

What is FK-C1 Ball Valves Type Hydraulic Quick Coupling?

The FK-C1 Ball Valves Type Hydraulic Quick Coupling incorporates an internal ball valve that ensures a secure, leak-proof seal when the coupling is disconnected. This feature is especially useful in applications where fluid containment is essential, such as in high-pressure systems or environments where spills or leakage would be problematic.

The FK-C1 Ball Valves Type Hydraulic Quick Coupling offers easy operation, as it automatically shuts off the flow of hydraulic fluid when uncoupled. These couplings are designed for use in industries such as construction, mining, and automotive, where safety and operational efficiency are key considerations.



The FK-C1 Ball Valve Type Hydraulic Quick Couplingis specifically designed for high-pressure hydraulic systems, offering exceptional sealing performance and durability. 

Its unique ball valve structure ensures smooth fluid flow while preventing leakage, making it an essential component in industrial machinery, construction equipment, and hydraulic systems.

Key Features


◆ Ball Valve Structure

The FK-C1 adopts a ball valve design, which provides superior sealing compared to needle or poppet valve couplings, ensuring stable fluid control under high-pressure conditions.


◆ High-Pressure Resistance

This coupling can withstand working pressures of several hundred bar, making it ideal for high-load hydraulic transmission systems, ensuring stable operation even under extreme conditions.


◆ Premium Materials

Body Material:

Typically made from zinc-plated carbon steel or stainless steel, offering excellent corrosion resistance and mechanical strength.


Seals:

Available in NBR (Nitrile Rubber), FKM (Fluorocarbon Rubber), and PTFE (Polytetrafluoroethylene), ensuring wear resistance and chemical stability under different operating conditions.


◆ Quick Connection and Disconnection

The one-hand operation quick-connect design allows for easy insertion and removal without additional tools, improving efficiency and reducing downtime.


◆ Excellent Compatibility

The FK-C1 series complies with ISO standards, making it interchangeable with similar quick couplings available on the market, ensuring seamless integration into various hydraulic systems.


◆ High Impact Resistance

The robust construction of the FK-C1 ensures it remains securely sealed even under hydraulic shock or mechanical vibrations, preventing loosening or leakage.



Applications


The FK-C1 Ball Valve Type Hydraulic Quick Coupling is widely used in the following industries:


◆ Construction Machinery: 

Excavators, loaders, bulldozers, cranes, and other hydraulic systems requiring frequent connection and disconnection.


◆ Industrial Hydraulic Equipment: 

Hydraulic presses, power units, and testing equipment.


◆ Agricultural Machinery: 

Tractors, harvesters, and sprayers with hydraulic piping systems.


◆ Oil & Gas Industry: 

Hydraulic-driven equipment and fluid transfer systems requiring high-performance couplings.


◆ Marine & Offshore Equipment: 

Deck machinery and hydraulic lifting systems that demand corrosion-resistant hydraulic connections.



Usage Guidelines


◆ Proper Installation

Ensure the hydraulic system is depressurized before connecting or disconnecting the coupling. Inspect the seals for any signs of wear to prevent leaks.


◆ Avoid Overpressure

FK-C1 couplings are designed for specific pressure ranges. Continuous overpressure use may compromise sealing performance and lifespan.


◆ Regular Maintenance

Clean the coupling periodically to prevent dirt and debris from entering the hydraulic system, which could affect performance.


◆ Choose the Right Sealing Material

Select the appropriate sealing material based on the working environment. For high-temperature applications, FKM seals offer better heat resistance.
