Product Overview
This 3 Way Brass Ball Valve is a general-purpose multi-way fluid control valve with high-quality brass material as the core, adopting L/T port 3 way flow channel design. It drives the ball to rotate 90° through the handle to accurately realize medium reversing, diverting, converging and cross switching in pipelines.
Relying on the excellent machinability, corrosion resistance, frost resistance and high cost performance of brass material, it has the characteristics of compact structure, light operation, reliable sealing and convenient installation. It is the most widely used valve product in civil and industrial small-bore multi-way pipeline systems.
Available in full sizes DN8–DN50 (NPS 1/4″–2″), it strictly complies with global general valve standards including GB/T 12237, EN 13828 and ISO 228. Widely used in civil water supply and drainage, HVAC, gas transmission, solar hot water, water purification equipment, plumbing and sanitary ware and other fields.
Key Features
- Core High-Quality Brass Body, Excellent Corrosion & Frost ResistanceThe product fully focuses on the core advantages of brass material. All core parts including valve body, ball and stem are integrally formed by precision hot forging of HPb59-1 national standard lead brass, CW617N European standard environmental protection brass, lead-free food grade brass. The material is dense without sand holes and blowholes, with excellent rust resistance, water corrosion resistance, frost resistance and deformation resistance, no risk of brittle cracking in low temperature environment.The lead-free environmental protection model fully complies with drinking water sanitary standards, no heavy metal precipitation, safe and non-toxic, perfectly suitable for drinking water and food-grade medium working conditions. The excellent thermal conductivity of brass can effectively avoid valve body condensation and freezing cracking under alternating cold and hot medium conditions, with a service life much longer than ordinary cast iron and zinc alloy valves.

L/T Port 3 Way Flow Channel, Multi-Function for Full Scenarios
The core adopts an integrated L/T port flow channel brass ball, the inner wall of the flow channel is smooth with low flow resistance and no medium retention dead angle, which accurately matches the needs of different working conditions:
L Port Flow Channel: Realizes accurate two-way medium reversing and single-line on-off switching, suitable for opening, closing and cross reversing control of 2 independent pipelines, replacing the combined function of 2 two-way valves, often used in HVAC cold and hot water switching and water circuit reversing scenarios;
T Port Flow Channel: Realizes synchronous control of medium diverting, converging and three-way mixing, suitable for uniform distribution and convergence of multi-pipeline media, replacing the combined function of 3-4 two-way valves, greatly simplifying the pipeline layout, often used in multi-way water supply and medium mixing scenarios.
- Standard Internal Thread Connection, Easy Installation & Space Saving
The full series is equipped with GB/BS/ANSI universal internal thread interface as standard. The thread specifications are 100% in line with the three mainstream thread standards: G/BSPT (British pipe thread), NPT (American taper pipe thread), Rp (GB cylindrical pipe thread), which can be directly seamlessly connected with threaded pipelines and fittings of the same specification.
No hot work welding, no flange matching is required, installation and disassembly can be completed with a common wrench, convenient and efficient operation. The valve body has a compact structure and small volume, which is perfectly suitable for civil pipelines with limited space and equipment built-in pipeline installation scenarios, greatly reducing on-site construction and maintenance costs.
- Floating Ball Soft Seal Structure, Bidirectional Zero Leakage & Light Operation
Adopting the core floating ball structure, the medium pressure pushes the ball tightly against the downstream valve seat to realize the self-tightening sealing effect of the higher the pressure, the tighter the seal. Standard equipped with food-grade PTFE/RPTFE wear-resistant soft seal seat, which is paired with the brass ball by high-precision grinding, the sealing grade reaches ANSI B16.104 Class VI bidirectional zero leakage, no wear during long-term opening and closing. The opening and closing torque is extremely small, the handle operation is light and smooth without jamming, suitable for frequent opening and closing requirements in civil and industrial scenarios.
- Humanized Safety Structure Design, Stable & Durable Maintenance-Free
The full series is equipped with a bottom-mounted T-type blow-out proof stem as standard, even under abnormal overpressure working conditions, there will be no safety accident of stem rushing out, suitable for high pressure working conditions such as gas. The stem adopts O-ring + packing double seal, no external leakage during long-term operation. The handle is designed with 90° precise limit, and can be equipped with a lock to prevent misoperation, ensuring the safe operation of the pipeline. The two-piece valve body structure is easy to disassemble and assemble, the wearing parts such as valve seat and packing are easy to replace, and the operation and maintenance cost in the whole life cycle is extremely low.
Applications
Civil building water supply and drainage & plumbing systems, HVAC cold and hot water reversing pipelines, civil/commercial gas transmission pipelines, solar/air energy hot water circulation systems, household/commercial water purification equipment, small hydraulic and pneumatic systems, food and beverage small transmission pipelines, garden irrigation multi-way water distribution systems, boiler auxiliary equipment pipelines.
Product Summary
This 3 Way Brass Ball Valve firmly focuses on the core advantages of brass material, and has the core characteristics of 3 way multi-channel reversing and diverting function, convenient installation with standard thread, bidirectional zero leakage, frost and corrosion resistance, light operation and high cost performance.
Covering full small-bore sizes from DN8 to DN50, it adapts to the global mainstream thread standards and civil and industrial small-bore working condition requirements. It is the preferred cost-effective valve for medium reversing, diverting and converging control in multi-way pipeline systems.
