Instrument Needle Valves

Instrument needle valves use a precision tapered needle-shaped stem to achieve accurate control of very small flow rates. The valve stem features a slender, tapered design resembling a needle. By turning the handwheel, the stem moves up and down, allowing precise flow regulation or complete shut-off of the fluid passage.

With a compact structure and excellent sealing performance, instrument needle valves can operate reliably under high-pressure and high-viscosity media conditions. They are primarily used in instrument measurement and tubing systems to control the on/off flow of media and provide precise flow regulation. As a key component of industrial process systems, instrument needle valves play an essential role in ensuring accurate and reliable fluid control.

Q: What type of company are you?: A: We are an integrated manufacturer and trader (industrial and trading).

Q: What types of valves do you produce?: A: We specialize in producing threaded gate valves, globe valves, check valves, ball valves, strainers/filters, and more. We can also manufacture non‑standard products according to customer requirements. Our valves are available in three pressure‑rating grades to suit different pipeline working conditions: Light‑duty PN10, Medium‑duty PN16, and Heavy‑duty PN25. The higher the grade, the greater the wall thickness, pressure‑bearing capacity, and structural stability. Customers can select the appropriate grade based on their project’s pipeline pressure and operating environment.

Q: What are the common materials used for your valves?: A: We offer 201 stainless steel, 304 stainless steel, and 316 stainless steel to meet different anti‑corrosion, weather‑resistance, and media requirements.
● 201 is cost‑effective and suitable for general residential use, HVAC, and clean water applications.
● 304 offers good corrosion resistance and stability, widely used in water treatment, municipal projects, and general chemical scenarios.
● 316 provides stronger acid and alkali resistance, ideal for demanding conditions in chemical, pharmaceutical, and fluid‑handling systems with complex media.
All raw materials are inspected upon incoming receipt. The standard working temperature range is 0°C to 80°C, and we also support custom material specifications upon request.

Q: In which industries and applications are your products mainly used?: A: Our valves are suitable for a wide range of applications, including petroleum, chemical, natural gas, industrial water treatment, municipal water supply and drainage, HVAC engineering, pharmaceuticals, food & beverage, dairy, and many other fluid control systems. They are compatible with most conventional industrial and civil pipeline projects.
