Based on aggregated insights from structured factory profiles within the CNFX directory, the standard Needle Valve used in the Machinery and Equipment Manufacturing sector typically supports operational capacities ranging from standard industrial configurations to heavy-duty production requirements.
A canonical Needle Valve is characterized by the integration of Needle and Valve Body. In industrial production environments, manufacturers listed on CNFX commonly emphasize Stainless Steel construction to support stable, high-cycle operation across diverse manufacturing scenarios.
A precision flow control valve that uses a tapered needle to regulate fluid passage through an orifice.
Technical details and manufacturing context for Needle Valve
Commonly used trade names and technical identifiers for Needle Valve.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 6000 psi (413 bar) depending on size and material |
| flow rate: | 0.01 to 100 GPM (0.04 to 378 LPM) depending on orifice size |
| temperature: | -20°C to 200°C (standard), up to 400°C with special materials |
| slurry concentration: | Not recommended for slurries >5% solids by volume; fine particulates may cause needle wear |
Manufacturer profiles with relevant production capability in China
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Not customer reviews or live demand data. These dimensions support RFQ preparation and supplier evaluation.
These scores are example evaluation dimensions, not real customer ratings, country-specific buyer feedback, or live inquiry activity.
Needle valves are used for precise flow regulation in hydraulic systems, lubrication lines, instrumentation, and process control applications where fine adjustment of fluid flow is required.
The tapered needle allows gradual restriction of the orifice opening, enabling precise metering of fluid flow with high resolution adjustment, making it ideal for applications requiring accurate flow rates.
Regular inspection of seals and seating surfaces, periodic lubrication of the stem threads, and checking for leaks around the valve body. PTFE seals typically require less maintenance than other materials.
