Founded in 2011, Wofly Technology specializes in high-purity fluid control valves and components, and provides integrated gas distribution systems. Our ISO 9001-certified product portfolio-including diaphragm valves, pressure regulators, and precision instrumentation valves-complies with CE, RoHS, and SEMI S2 standards.
Engineered for critical applications in semiconductor fabrication, hydrogen energy infrastructure, and photovoltaic manufacturing, our solutions ensure leak-tight performance in ultra-clean environments.
With 14-year commitment to advancing gas handling safety, Wofly delivers certified reliability through rigorous quality management systems, supporting global clients in mission-critical industries.
The founding team has been engaged in the design and development of semiconductor high-purity pipe valves for nearly 20 years, the introduction of the core technology of the valve industry in the United States, and constantly explore and innovate the development of high-quality and cost-effective ultra-high-purity diaphragm valves, pressure reducing valves, automatic switching systems and related products, and is committed to becoming a first-class ultra-high-purity fluid system fitting provider.


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.
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.
