Features
1. Metal to metal seal provides leak-free service in vacuum to high pressure range.2. Small internal volume, can completely purge the flow path.
3. Fully wrapped seat design, with superior anti-expansion and anti-pollution capabilities.
4. Nickel-cobalt alloy diaphragm for higher durability and corrosion resistance.
5. The standard roughness is Ra0.25μm(BA-class) or electrolytically polished Ra0.13μm(EP-class).
6. Helium test leakage rate <1×10^-9 mbar.l/s.
7. Pneumatic actuators are available.Actuator type can be selected as handle, normally open or normally closed.
8. Pneumatic valve life up to 3 million times.
1. 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.
Class 100 clean workshop: Class 100 clean workshop is the workshop with the highest cleanliness, which is suitable for the production of products that require extremely high air cleanliness, such as integrated circuits and high-precision optical devices. In a class 100 clean workshop, the number of dust particles and microorganisms with a diameter greater than 0.5µm per cubic unit of air shall not exceed 100.
Class 1000 clean workshop:Class 1000 clean workshop is suitable for the production of products that require high air cleanliness, such as medical devices and medicines. In a class 1000 clean workshop, the number of dust particles and microorganisms with a diameter greater than 0.5µm per cubic unit of air shall not exceed 1000.
2. Production strengthWofly 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.
