Brass Mini Compression Quick Open Ball Valve

This Brass Mini Compression Quick Open Ball Valve is a compact manual straight-through valve engineered for water and HVAC piping systems, serving as a core component for pipeline on-off control. It is widely applied to domestic water supply, floor heating/radiator systems, floor heating manifolds, and piping for small equipment to quickly cut off or restore water flow. Its core strengths lie in compact construction, dependable sealing and easy operation.

The main body features one external thread end and one compression-type quick-connect end, requiring no welding for installation and adapting to standard pipeline fittings. Forged from premium brass, the valve body undergoes mirror chrome plating to deliver a bright silvery metallic finish. It boasts outstanding corrosion and impact resistance, resisting rust and deformation over long-term service, and is compatible with most domestic fluid media, especially suited for frigid northern regions. The chrome layer boosts surface wear resistance, preventing rust and scratches even under outdoor 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 strong pressure resistance to withstand water pressure surges in standard household water supply systems, while the chrome coating inhibits limescale buildup to further extend service life.

Compression End for Copper Tubes

Fits standard copper tubes with outer diameters of 15mm and 22mm. The double ferrule nut design eliminates welding: tightening the nut makes the ferrule edges bite tightly onto the copper tube outer wall to form dual leak-proof seals for hassle-free installation. The anti-slip hexagonal nut works with standard wrenches to simplify mounting and disassembly, matching common copper piping systems in residential renovations.

Metric External Thread End

Standard external threads (common sizes: G3/4, G1) enable direct quick connection to equipment ports and male threaded fittings. It perfectly fits water inlets of water heaters, wall-hung boilers and radiators without extra adapters, compatible with most household piping renovation projects.

Straight Full Bore Structure

The full straight bore minimizes fluid resistance without reducing pipeline flow. Equipped with a hexagonal union nut and flat sealing structure, it achieves leak-free connection with flat gaskets, requiring no welding or PTFE tape. For later equipment maintenance, simply unscrew the nut instead of removing entire pipe sections to cut maintenance costs drastically.

The built-in full-bore spherical spool creates an unobstructed flow path when fully open for high flow capacity. Compared with traditional angle valves, it generates far less water resistance, resolving low water pressure and slow water output for water heaters and heating pipelines.

Operation Handle & Stem Sealing

A short black ABS engineering plastic handle sits atop the Brass Mini Compression Quick Open Ball Valve with a 90° on-off design for effortless operation; full open/closed status is clearly visible with a simple flip, no tools required. The valve stem features drip-proof sealing with built-in PTFE gaskets that resist aging and extreme temperatures, preventing leakage after frequent switching. It accommodates cold and hot water (-20℃ to 100℃), low-pressure gas and other media.

The short ABS handle saves vertical installation space, ideal for confined areas such as under cabinets, suspended ceilings and narrow pipe shafts to prevent collision with walls or cabinets during operation. All threaded connections are tool-mounted without welding; pipes remain intact during maintenance or replacement for low upkeep costs.

Operation Notice

The handle only rotates 90° for switching. Do not apply excessive torque, as this may damage the spool structure.

With its mini compact profile, this Brass Mini Compression Quick Open Ball Valve is perfectly suited for cramped spaces including under cabinets, inside equipment and narrow pipe shafts. Unlike large-handle conventional ball valves, its short handle avoids blockage by surrounding equipment after installation. The brass material meets hygiene standards for drinking water pipelines, making it a cost-effective solution for pipeline flow control in residential and small engineering projects.
