Brass Female Thread Double-Handle Ball Valve

This Brass Female Thread Double-Handle Ball Valve is a straight-through fluid control valve featuring a forged brass valve body, female threaded connections on both ends, and a butterfly handle design, enabling rapid on-off control of pipelines. It is widely used in residential plumbing, HVAC, gas, and industrial low-pressure fluid systems, making it one of the most common switch control accessories in household pipeline applications.

The main body is integrally forged from high-purity brass with the surface retaining a matte brass finish, offering excellent corrosion resistance and impact resistance. It resists rusting and deformation during long-term use and is compatible with most civilian fluid media, especially suitable for cold northern regions. The treatment also enhances surface wear resistance (resistant to rusting and scratching under outdoor sun and rain exposure), with a service life far exceeding that of ordinary zinc alloy/plastic valves. The valve body is integrally formed without pinholes or cracks, with strong pressure resistance capable of withstanding a standard working pressure of 1.6MPa, meeting the safety requirements of household water supply systems.

Both ends feature standard female threaded connections (compatible with G1/2, G3/4, G1 and other conventional pipe thread specifications), allowing direct and quick connection to male threaded fittings, water pipes, and equipment interfaces. It is compatible with conventional residential PPR pipes, galvanized pipes, and stainless steel pipe systems.

The threads are manufactured using precision rolling technology, with neat tooth profiles and no burrs. Reliable sealing can be achieved with PTFE tape or sealant, ensuring convenient installation and adaptability to most residential pipeline renovation scenarios.

The built-in full-bore spherical valve core ensures a throttling-free and obstruction-free flow path when open, achieving zero-resistance high-flow capacity. Compared to traditional globe valves, water/air flow resistance is significantly reduced, making it suitable for flow-sensitive equipment such as water heaters, wall-hung boilers, and gas pipelines.

The top is equipped with a chrome-plated metal butterfly handle with a red ABS anti-slip sleeve featuring anti-slip texture, ensuring a stable grip even when wet or oily, preventing slipping during operation. The plastic material also provides insulation and heat protection, preventing burns from heat transferred through hot water or gas pipelines, enhancing operational safety. The 90° switching design allows for easy and effortless operation, with switch status clearly visible at a glance. Full opening and full closing can be achieved with a simple flick without the need for additional tools.

The valve stem adopts a drip-proof sealing design with built-in PTFE (Polytetrafluoroethylene) sealing rings, offering excellent aging resistance and wide temperature adaptability, maintaining leak-free performance after long-term frequent switching. This Brass Female Thread Double-Handle Ball Valve is compatible with multiple media including cold and hot water (-20℃~100℃), low-pressure gas and other media.

Threaded connections require no welding—only a wrench is needed for installation and disassembly. Subsequent maintenance, inspection, and replacement can be done without damaging the pipeline, resulting in low maintenance costs.

The handle only supports standard 90° rotational switching. Do not apply excessive twisting force to avoid damaging the internal valve core structure.

With its brass valve body, full-bore high-flow capacity, and quick-action butterfly handle, this Brass Female Thread Double-Handle Ball Valve balances practicality and durability. It is an efficient and versatile general-purpose control solution for residential and small-scale engineering pipelines, making it a trustworthy choice in pipeline control applications.
