High Pressure Capability: This 1/4" precision high pressure stainless steel needle valve is designed to handle high pressure applications with working pressures up to 6000psi and is suitable for a variety of industries such as semiconductor manufacturing.
Multi-Media Compatibility: The valve is compatible with a wide range of operating media, including oil, gas, and air, making it versatile for its application.
High reliability: because there are no complicated electronic components and driving devices, the manual stainless steel needle valve is not easily affected by electrical faults, electromagnetic interference and other factors, and has high reliability. In some harsh working environments, such as high temperature, humidity and strong electromagnetic interference, the manual needle valve can work stably to ensure the normal operation of the system.
CE Certification: The product complies with the safety standards of the European Union, as indicated by its CE certification, ensuring compliance with regulatory requirements.
Customization Options: AFLOK offers OEM and ODM customization support, allowing customers to customize products to their specific needs, including "user-input" designs.
Durability & Warranty: The valves are manufactured with high-quality stainless steel and come with a one-year warranty to give customers peace of mind that the performance will last.

Q1: What materials are the valve body and stem made of?
A1: Common valve body materials include stainless steel, brass, etc. The stem is usually made of stainless steel.
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 6000psi 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.
Q8:What is the function of needle valve?
A8: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.
