Q21F Female & Male Thread Brass Ball Valve Overview

The Q21F Female & Male Thread Brass Ball Valve is a compact ball valve designed with combined female and male thread connections. Its body and key components are constructed from forged brass. One end of the valve features external threads (e.g., G-thread), while the opposite end has internal threads, facilitating convenient connection and adaptation between pipelines or equipment with different interface standards. A 90-degree rotation of the stem drives the ball to open or close the flow path quickly. The valve seat, made of soft sealing materials like PTFE (Polytetrafluoroethylene), ensures reliable sealing. Characterized by its compact and refined design, this valve integrates both connection/adaptation and shut-off functions. It is suitable for non-corrosive media such as water, oil, and air, with typical working pressures ranging from PN16 to PN40. Widely used in HVAC systems, small-scale equipment, instrumentation, and domestic water supply applications, it serves as a versatile pipeline connection and control component.

Q21F Female & Male Thread Brass Ball Valve Features

1. Combined Female & Male Thread Connections: Features a special design with external threads on one end and internal threads on the other, allowing direct connection to pipelines or equipment with different interfaces. Eliminates the need for additional adapters, enabling flexible and convenient installation.

2. Corrosion-Resistant Brass Body: Manufactured from forged brass, offering high strength, excellent corrosion resistance, and resistance to rust, resulting in a long service life.

3. Excellent Sealing and Smooth Operation: Equipped with a PTFE seat for reliable soft sealing. The low friction coefficient ensures minimal opening/closing torque and smooth, effortless manual operation.

4. Compact and Multi-Functional Design: Integrates both connection/adaptation and shut-off functions in one compact unit. Its short face-to-face length saves installation space, making it ideal for retrofit or connection applications in space-constrained environments.

5. Cost-Effective and Easy Maintenance: Low manufacturing cost. Sealing components can be replaced if the seat wears out, facilitating easy maintenance. A high-value, economical choice for shut-off and connection control in various low-pressure pipeline systems.
