Durable, Corrosion-resistant Valves For Plumbing And Heating
3-piece copper ball valve offers reliable flow control and shut-off in plumbing, heating, and gas systems, with superior corrosion resistance and easy maintenance.
3-Piece Copper Ball Valve is a high-performance flow control device designed for precise regulation and shut-off in plumbing, heating, and gas systems. Compliant with standards like API 608, ASME B16.34, and GB/T15185, these copper ball valves are constructed from bronze (C95800, B62) or copper alloys, offering exceptional corrosion resistant ball valve properties. Widely used in residential, commercial, and industrial applications such as water supply, HVAC, and medical gas systems, they provide reliable pipeline flow control under pressures up to 600 PSI and temperatures ranging from -20°C to 150°C, ensuring robust performance in diverse environments.
Manufactured through precision casting or forging, the 3-piece copper ball valve features a modular design with a body and two end caps bolted together, allowing easy disassembly for maintenance without removing the valve from the pipeline. Available in sizes from 1/4" to 4" (DN6 to DN100), they support threaded (NPT, BSP), solder, or copper stub connections, with full port designs ensuring minimal flow resistance. The valve’s ball, typically made of stainless steel (ASTM A182 F316), rotates 90° for quick shut-off, while PTFE seats provide leak-free sealing. Surface treatments like passivation enhance corrosion resistance, making them ideal for water, gas, and mildly corrosive media.
3-Piece Copper Ball Valves undergo rigorous testing, including hydrostatic, leakage, and pressure tests, to comply with API 598 and GB/T13927 standards. With a minimum tensile strength of 485 MPa and yield strength of 170 MPa for C95800 bronze, these valves ensure durability in demanding conditions. Their quarter-turn operation enables rapid flow control, while the full port design minimizes pressure loss, making them suitable for full port ball valve applications in HVAC and water distribution. Features like blowout-proof stems and locking handles enhance safety, with oxygen-cleaned options available for medical gas systems.
Compared to 1-piece or 2-piece ball valves, the 3-piece copper ball valve offers superior maintenance flexibility, as internal components can be repaired or replaced in-line. Certified by NSF/ANSI 61 for potable water and API 607 for fire-safe performance, these valves support manual, pneumatic, or electric actuation for versatile control. Their compact design and low torque requirements facilitate easy installation, while copper’s thermal conductivity makes them ideal for heating systems. Specialized versions, such as those with gauge ports, cater to specific needs like medical gas applications.
Addressing challenges like corrosion, leaks, and frequent maintenance, 3-Piece Copper Ball Valves deliver reliable, efficient solutions for fluid control systems. Their corrosion-resistant copper alloy construction, easy maintenance, and precise shut-off make them a preferred choice for engineers seeking durable industrial ball valves. Backed by Sunny Steel’s white-glove service, these valves ensure exceptional performance, safety, and longevity in plumbing, heating, and gas applications.
Durable, corrosion-resistant, and easy to maintain for water, oil, gas, and heating systems. Designed for long service life, easy disassembly, and compliance with international standards.
A 3 piece copper ball valve consists of three main parts: the central body and two end caps held together by bolts. The copper body ensures excellent corrosion resistance and thermal conductivity, making it ideal for plumbing, heating, and gas systems. The 3 piece design allows disassembly without removing the valve from the pipeline, simplifying maintenance and reducing downtime.
Copper naturally resists rust and scaling, ensuring long-lasting performance in water and gas systems.
Excellent heat transfer makes these valves ideal for heating and hot water distribution systems.
3 piece design allows disassembly for cleaning or part replacement without pipeline removal.
Precision-machined seats provide excellent sealing, minimizing leakage risk.
Copper’s thermal properties enhance energy efficiency in heating and hot water systems.
Suitable for residential, commercial, and industrial use in water, oil, and gas systems.
Designed and manufactured according to ASME and API standards, with rigorous testing for quality assurance.
