Our Advantages

1. Compared to other low-quality products, our valves and fittings are durable, and the body of the product is mostly made of stainless steel 316 or 316L, which has a smooth appearance and the picture matches the real thing. Orbital welding is adopted, the smoke generated during welding is small, environmentally friendly, and the surface finish is brighter than ordinary manual welding. Provide consistent weld quality, excellent weld quality, and meet the requirements of precision instrument valves. All the main parts are produced by themselves, and the machining workshop is equipped with CNC machine tools and turning and milling compound lathes to ensure the consistency and stability of quality from raw materials and bars to finished products.

2. Clean workshop assembly: All products have been assembled in class 100 and class 1000 clean workshops, and 100% of them have passed the helium seal test and functional test before leaving the factory.At present, Wofly has built class 100 (over 100m2) and class 1000 (over 500m2) dust-free workshops.The cleaning workshop is divided into welding area, assembly area, testing area, finished product storage area, etc., and each area does not interfere with each other and produces in an orderly manner.

3. Our standard BA-grade and EP-grade products meet the ASME B16.34 standard and Clean packaging meet the ASME G93 C standard.
 

FAQ

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 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.

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.
