FAKB Series Threaded Type

Quick-connect connector on one end + external threaded direct connection on the other end

Built-in one-way valve core ensures unidirectional gas flow and prevents backflow.

Body: Brass plated with nickel, corrosion resistant, high strength, and compact size.

The quick-connect end features a locking and sealing structure, ensuring a secure and reliable seal upon insertion.

The valve body features an airflow direction arrow, clearly indicating the installation direction.

    Detailed description

    The FAKB Series threaded type is designed with a quick-connect connector on one end and an external threaded direct connection on the opposite end. This combination allows for straightforward integration between tubing and threaded ports, providing a practical solution for connecting pneumatic lines to components such as valves, cylinders, or manifolds without requiring additional adapters.

    A built-in one-way valve core is incorporated to ensure unidirectional gas flow and prevent backflow within the circuit. This feature helps maintain the intended direction of air movement, reducing the risk of unintended cylinder movement or pressure fluctuations that could affect system performance. The valve core is designed to operate reliably under normal working conditions, supporting consistent functionality over time.

    The body is constructed from brass with a nickel-plated finish, offering a combination of mechanical strength and corrosion resistance. The plated surface helps protect against oxidation and environmental exposure, contributing to the longevity of the component in industrial or automated settings. The compact size of the FAKB Series further enhances its suitability for installations where space is limited, allowing multiple units to be placed in close proximity without interfering with adjacent components.

    On the quick-connect end, a locking and sealing structure is integrated to create a secure connection upon tube insertion. The locking mechanism holds the tubing firmly in place, while the sealing element provides a reliable barrier against leakage. This design supports quick assembly and disassembly without the need for tools, simplifying both initial installation and routine maintenance.

    To assist with proper orientation during installation, the valve body includes a clearly marked arrow indicating the direction of airflow. This marking helps reduce the likelihood of reverse installation, supporting correct circuit configuration and contributing to reliable operation.

    The FAKB Series threaded type is suited for applications requiring dependable unidirectional flow, corrosion-resistant construction, and efficient connection between tubing and threaded ports.
