Copper Needle Valve
Manufacturer,Stockist and Exporter of Copper Needle Valve
Copper Needle Valves are vital components in fluid and gas systems, offering precise control over flow rates. Designed for high-performance applications, these valves ensure smooth, controlled operations in industrial, commercial, and residential setups.
Sumer Metal Industries Private Limited is a trusted manufacturer, supplier, and exporter of Copper Needle Valves. With decades of experience, the company provides high-quality valves that meet international standards and industry certifications.
These valves are exported to multiple countries including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, and various regions in Africa, highlighting their global reliability and demand.
Copper Needle Valves are manufactured using high-grade Copper alloys such as CW617N, CZ121, or C37700. This ensures corrosion resistance, strength, and long-term durability in diverse working environments.
The chemical makeup typically includes 59–63% copper, balance zinc, 2.5–3% lead, and minimum 0.35% iron. This composition guarantees machinability, corrosion resistance, and structural integrity.
Copper Needle Valves exhibit tensile strength of 338–469 MPa, yield strength of 124–310 MPa, hardness of 80–100 HRB, and a modulus of elasticity of 103.4 GPa, ensuring they withstand high pressures and mechanical stress.
Designed for demanding applications, these valves can handle pressures up to 10,000 psi and temperatures from -20°F to 450°F (-29°C to 232°C), making them suitable for both low and high-temperature operations.
Copper Needle Valves allow precise control of fluid and gas flow. Available in 2-way and 3-way configurations, they provide accurate throttling and shut-off functions in various piping systems.
These valves come with diverse connection types such as threaded (NPT, BSPT, BSPP), flanged, socket weld, and butt weld, making them adaptable for multiple industrial and commercial piping systems.
Specification Of Copper Needle Valve
| Attribute | Detail / Typical Value |
|---|---|
| Model | Copper Needle Valve - Standard Series (Sumer Metal) |

Sealing is typically achieved using PTFE or graphite, ensuring leak-proof performance. Handles are offered in manual, pneumatic, or electric actuator types depending on system requirements.
Common applications include instrumentation, HVAC systems, gas pipelines, chemical processing, water treatment plants, and laboratory setups where precise flow control is essential.
Sumer Metal Industries offers customization in size, connection type, handle type, and seal material to meet specific industry needs, ensuring optimal performance for every system.
Each valve undergoes rigorous quality testing, including hydrostatic testing, dimensional inspections, and material certifications. This ensures compliance with ANSI, ASME, ISO, ASTM, and JIS standards.
Chemical Properties Of Copper Needle Valve
| Element | Typical Range / Role |
|---|---|
| Copper (Cu) | Major constituent — primary corrosion resistance & conductivity |
| Zinc (Zn) | Alloying element to form brass — improves strength and machinability |
| Lead (Pb) | Small amounts in free-machining brasses (if used); optional and often limited for drinking-water applications |
| Tin (Sn) / Nickel (Ni) | Minor additions in some alloys to enhance corrosion resistance |
| Other (Fe, P) | Trace elements from alloy or machining process |
As a vertically integrated manufacturer, Sumer Metal oversees casting, machining, surface finishing and assembly, which allows tight quality control and competitive lead times. Their in-house testing includes leak tests, seat pressure checks and cycle life testing to meet customer specifications. The valves are available in various end connections (compression, flare, BSP/NPT threads) and options such as lock-nuts, protective caps and stainless steel stems for more aggressive environments.
Sumer Metal acts as supplier and exporter, serving markets across the Middle East (Oman, Qatar, Saudi Arabia, the UAE, Kuwait), Europe (Spain, Germany), North America (USA, Canada) and several regions across Africa. Their export packaging, documentation and customs support are geared for international shipments and project deliveries — helping OEMs, MROs and distributors receive valves ready for immediate installation.
The Copper Needle Valve product line emphasizes corrosion resistance and thermal stability inherent to copper alloys used in the bodies, combined with precision-machined sealing surfaces for minimal leak rates. Typical applications include instrumentation panels, hydraulic pilot lines, gas sampling, laboratory equipment and any system requiring slow, proportional throttling of liquid or gas.
