Low-Pressure Brass Ball Valve with Butterfly Handle and Hose Connector: Design, Performance, and Manufacturing Strengths

YH-207 Brass Ball Valve with Butterfly Handle（M/hose connector）

Reliable fluid-control components are essential in household gas installations, water connections, portable equipment, and light commercial applications. A valve may be small in size, but it performs a critical function: controlling the passage of a medium, isolating equipment, supporting maintenance, and helping users operate a system safely. For these reasons, the choice of valve should be based on more than appearance or purchase price. Connection compatibility, sealing performance, material quality, operating comfort, pressure range, corrosion resistance, and manufacturing consistency all influence long-term value.

The YH-207 brass ball valve with butterfly handle and male hose connector is designed for applications that require a compact, practical, and versatile shut-off solution. Its integrated external thread and hose connector allow it to connect with rigid threaded pipe and flexible hose systems. This dual-interface configuration reduces the number of adapters required during installation and gives installers greater flexibility when working with household appliances, portable gas equipment, and small-scale fluid systems.

The valve is also optimized for low-pressure service. With a nominal pressure of 0.015 MPa, it is intended for suitable low-pressure gas and fluid applications rather than high-pressure industrial service. Its forged brass body provides a durable foundation, while the butterfly handle gives users a broad, easy-to-grip control surface and a visible indication of the valve position. Together, these features create a product that combines straightforward installation, accessible operation, and dependable everyday service.

Product Overview

The YH-207 belongs to the brass hose ball valve category. It uses a ball-type shut-off mechanism, which is generally valued for its simple quarter-turn operation and relatively direct flow path. When the internal ball is rotated to the open position, the passage aligns with the connected piping. When rotated to the closed position, the ball blocks the passage and isolates the downstream equipment.

The product incorporates a male threaded connection and a hose connector in one valve body. This arrangement is particularly useful where an installation transitions between a fixed pipe and a flexible hose. Instead of purchasing a separate valve, adapter, and connector, the installer can use one integrated component. Fewer connection points can simplify assembly and may reduce the opportunity for installation errors, although all connections must still be assembled and checked according to the applicable local requirements.

The butterfly handle is another defining feature. Compared with a small lever or narrow knob, a butterfly-shaped handle offers a larger gripping area. This can make manual operation more comfortable for users who wear gloves, have limited hand strength, or need to operate the valve in a confined household setting. The handle also provides a clear visual indication of the approximate open or closed position.

The valve body is manufactured from brass. Brass is widely used for fluid and gas fittings because it combines mechanical strength, machinability, dimensional stability, and resistance to corrosion in many ordinary environments. A forged brass construction can provide a robust body suitable for repeated handling and installation, while precision machining helps form the internal passages and connection features required for reliable assembly.

Core Operating Principle

A ball valve controls flow by rotating a drilled ball inside the valve body. The ball is supported and sealed by internal sealing elements. In the open position, the bore through the ball is aligned with the inlet and outlet passages. In the closed position, the solid side of the ball faces the passage, stopping the flow.

The quarter-turn operating principle is one of the main advantages of ball valves. A user generally does not need to rotate a handwheel through multiple turns. A short movement changes the valve from open to closed, which can be convenient during appliance maintenance or emergency isolation. The butterfly handle supports this operating principle by providing leverage and a visible orientation reference.

For low-pressure systems, sealing quality is especially
