External Thread Union Quick Open Ball Valve

This External Thread Union Quick Open Ball Valve is a rapid on-off control valve specially designed for home decoration and HVAC systems. It features a chrome-plated brass valve body with a connection structure of external thread on one end and a union nut on the other, paired with a short-handle quick-open ball valve design to swiftly control pipeline flow. Widely used for water heaters, wall-hung boilers, radiators, water purification equipment and other applications, it serves as a common fitting for terminal pipeline renovation and equipment installation.

The main body is forged from high-quality brass and finished with mirror chrome plating, delivering a bright silver metallic finish. It boasts outstanding corrosion and impact resistance, resisting rust and deformation during long-term service, and is highly suitable for cold northern regions. The chrome coating also enhances surface wear resistance, preventing rust and scratches even under outdoor exposure to sun and rain, granting a far longer service life than ordinary zinc alloy or plastic valves. The integrally formed valve body is free of pinholes and cracks with superior pressure resistance to withstand water pressure surges in standard household water supply systems. Its chrome plating effectively inhibits limescale buildup to further extend service life.

Ferrule-Type Copper Tube End

Compatible with standard copper tubes of outer diameters 15mm and 22mm, it adopts a double ferrule nut structure requiring no welding. Simply tighten the nut, and the cutting edges of the ferrules clamp the outer wall of the copper tube to form a double sealing barrier for leak-free performance and easy installation. The anti-slip hexagonal nut fits standard wrenches for effortless assembly and disassembly, matching common copper tube pipeline systems in residential plumbing.

It comes with standard metric external threads (common sizes including G3/4 and G1), enabling direct quick connection to equipment ports and external thread fittings. Perfect for water inlet ports of water heaters, wall-hung boilers, radiators and more, it eliminates the need for extra adapter joints and fits most household pipeline renovation scenarios.

Equipped with a hexagonal union nut and flat sealing structure, it achieves leak-tight connection with a flat gasket without welding or extra PTFE tape. Installation and removal are highly convenient; the nut can be unscrewed directly for equipment maintenance later without dismantling the entire pipeline, greatly cutting maintenance costs.

The built-in full-bore spherical spool creates an unobstructed flow channel when open for high flow capacity. Compared with traditional angle valves, it generates far lower water flow resistance, ideal for water heating and heating pipelines requiring ample water flow, and effectively resolves issues such as insufficient water pressure and slow water output.

A short handle made of blue ABS engineering plastic is mounted on the top with a 90° on-off design for effortless operation. The open/closed state is clearly visible; a simple flick fully opens or shuts off the valve without extra tools.

The valve stem adopts a drip-proof sealing design with built-in PTFE (Polytetrafluoroethylene) sealing rings that resist aging, high and low temperatures. It stays leak-proof after frequent switching, compatible with cold and hot water (-20℃ to 100℃), low-pressure gas and various other media.

The compact short ABS handle occupies minimal vertical space, making it suitable for confined areas such as cabinets, suspended ceilings and narrow pipe shafts, eliminating collisions with walls or cabinet panels during operation. Threaded connections require no welding—only a wrench is needed for installation and removal. Maintenance or replacement later does not damage pipelines, lowering overall upkeep costs.

Note: The handle only supports 90° rotation for switching. Do not twist it with excessive force to avoid damaging the spool structure.

With dual interface compatibility, welding-free installation, high flow capacity and superior sealing performance, this External Thread Union Quick Open Ball Valve delivers an efficient and convenient control solution for copper tube pipeline systems, balancing practicality and durability. It meets pipeline renovation demands for most residential and small-scale engineering projects, making it a reliable choice for pipeline control applications.
