Quick-Opening Brass Ball Valve with Cartridge Seat

This Quick-Opening Brass Ball Valve with Cartridge Seat is a compact manual straight-through ball valve specifically designed for water and HVAC piping systems. As a core component for controlling fluid flow, it is widely used in household water supply, underfloor heating/radiator systems, and small equipment piping applications. Its key advantages include a compact design, reliable sealing, and convenient operation.

One end features external threads, while the other is a quick-connect compression fitting, enabling installation without welding and compatible with standard piping fittings.

The body is forged from high-quality brass and finished with a mirror chrome plating process, giving it a bright, silvery metallic appearance. It offers excellent corrosion resistance and impact strength, resists rusting and deformation over long-term use, and is suitable for most common residential fluid media—especially ideal for cold northern regions. The surface also boasts enhanced wear resistance (resistant to rust and scratches from outdoor exposure to sun and rain), significantly extending its service life compared to ordinary zinc alloy or plastic valves. The valve body is one-piece molded, free of sand holes and cracks, with strong pressure resistance capable of withstanding water pressure fluctuations in typical household water supply systems. The chrome-plated surface effectively prevents scale buildup, further prolonging its lifespan.

Compression copper tube fitting: Compatible with standard copper tubes of outer diameters 15mm/22mm, featuring a double compression nut design. No welding required—simply tighten the nut to allow the compression sleeve edges to grip the outer wall of the copper tube, creating a dual seal. Installation is convenient and ensures no leakage risk. The nut features a non-slip hexagonal design, compatible with standard wrench tools for easier and more efficient installation and removal, ideal for common copper piping systems in residential applications.

Featuring standard metric external threads (common sizes such as G3/4, G1), it can be directly and quickly connected to equipment interfaces and threaded fittings, making it compatible with water inlet ports of water heaters, wall-mounted boilers, radiators, and other devices. With strong adaptability, it requires no additional adapters and suits most household plumbing retrofit scenarios.

The straight-through full-bore design ensures low fluid resistance and does not affect pipeline flow. Featuring a hexagonal compression nut and flat sealing structure, it achieves leak-free connections with just a flat washer—no additional welding or Teflon tape required. Installation and disassembly are convenient; during maintenance, the nut can be simply unscrewed without removing the entire pipe section, resulting in extremely low maintenance costs.

Equipped with a full-bore spherical valve core, the flow path remains unobstructed when open, enabling high flow rates. Compared to traditional angle valves, it offers lower water resistance, making it ideal for applications such as water heaters and heating systems where high flow is required, effectively preventing issues like insufficient water pressure and slow water discharge.

The top features a short black ABS engineering plastic handle with a 90-degree switch design, enabling effortless and convenient operation. The switch status is clearly visible, allowing for quick and easy full on/off control with just a simple flick—no additional tools required.

The valve stem features a drip-proof sealing design with an internal PTFE (polytetrafluoroethylene) seal, offering excellent resistance to aging and extreme temperatures. It ensures long-term operation without leakage and is suitable for various media including hot and cold water (-20°C to 100°C) and low-pressure gas.

The compact ABS handle design saves vertical space, making it ideal for installation in confined areas such as cabinets, ceilings, or narrow pipe shafts, preventing wall or cabinet impacts during operation. The threaded connection requires no welding—installation and removal can be completed with just a wrench. Maintenance and replacement are easy without damaging the piping system, resulting in low maintenance costs.

The handle supports only 90-degree operation; do not apply excessive force when turning to avoid damaging the valve core structure.

This Quick-Opening Brass Ball Valve with Cartridge Seat features a dual-interface design with external thread and quick-connect coupling, offering excellent adaptability. One end can be directly screwed into the internal threaded port of walls or equipment, while the other end quickly connects to hoses or rigid pipes, enabling flexible installation. Its compact form factor makes it ideal for space-constrained areas such as under cabinets, inside equipment, or narrow pipe shafts. Made of brass, it meets hygiene requirements for potable water systems, making it a cost-effective choice for on/off control in residential and small-scale plumbing applications.
