Package and Delivery
Export packing standard:Double plastic bags with internal vacuum and external plastic sealing+corrugated carton+ cardboard boxes+wooden pallet1. Clean process:The cleaning and packaging of products conform to ASTM G93 C standard.
2. What you see is what you get: What you see in our product pictures is exactly what you receive-the true embodiment of high-quality technology.
3. Surface roughness:Wofly's EP-grade product Surface roughness reached Ra 0.13 um ,BA-grade product Surface roughness reached Ra 0.25 um.
4. Purity applications: BA-grade products can be applied to gases below 6N purity,EP-grade products can be applied to 9N purity gases.
5. Compact design:Unlike other heavy and oversized valves, which take up too much space, our valves and fittings are compact in design and easy to operate.
1. Clean workshop
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.
2. Machining workshopWofly is different from those companies whose spare parts are provided by suppliers and assembled by themselves. All the accessories of Wofly are produced by ourselves, with strict quality control and unified quality standards. Accurate and advanced equipment is adopted to ensure the accuracy and cleanliness requirements of products.
