Definition : Needle valve - a valve device used to cut off or regulate the flow rate, with high adjustment accuracy.
The valve is needle-shaped, moving in the direction of the water flow, changing the area of the flow section, and is used to cut off or adjust the flow rate.
Our advantages
High Pressure Capability: This needle valve can withstand pressures up to 3000 psi (200 bar), making it suitable for demanding applications involving high pressures.

Q2: How is the quality of the product guaranteed? Are there any certifications?
A2: The products have undergone strict quality testing in the production process, in line with relevant industry standards, and have ISO and other quality certifications.
Q3: How about the sealing performance of the needle valve?
A3: The use of high quality sealing materials can ensure a good seal at 3000psi pressure and the leakage rate is very low.
Q4: How accurate is the flow control of the needle valve?
A4: Precise flow control can be achieved by fine-tuning the stem.
Q5: What are the precautions for installation?
A5: Make sure the pipeline is clean before installation, pay attention to the alignment and tightening strength of the threads during installation to avoid damage caused by too tightness.
Q6: How to carry out daily maintenance and repair?
A6: Check the condition of the seal regularly, clean the inside and outside of the valve, and replace the seal regularly according to the frequency of use and the medium.
Q7: What does after-sales service include?
A7: It usually includes the return and exchange of product quality problems, free maintenance and technical support within a certain period of time.
