| All-welded design, no internal threads. |
| When the upstream pressure is less than 0.14 bar(2 PSIG), the forward flow can be generated. |
| Working pressure high to 3000psig(206bar).If you need a one-way valve with pressure less than 3000psi, such as 1000 psi and 2000 psi, we can also meet it. |
| When the back pressure is less than 0.4 bar(2 PSIG), it can be closed. |
| Multiple end connections:Tube butt weld/Double ferrules /female VCR /male VCRconnection methods. |
| 316L stainless steel material with corrosion resistance.The standard average inner surface roughness is Ra20uin. (0.5um), electrolytic polishing to roughness Ra10uin. (0.25um) is optional. |
| Check valves are designed to control the direction of flow only and should never be used as a safety relief device. |
| Note: When a valve has not been opened for a period of time, its initial opening pressure may be higher than the set opening pressure. |
About this product

1. Exhibition hall and machining workshop
1. Technical services are available 24H/D.Our technical team can provide technical services for pre-sale, after-sale, installation and research and development of new products.
2. Compared with other low quality products, our valves and fittings are durable, most of the main body of the product is made of stainless steel 316 or 316L, the appearance is Smooth surface, and the picture matches the real thing. Adopt orbital welding, the smoke produced when welding is small, environmental protection, surface finish is brighter than ordinary manual welding. Provide consistent welding quality, excellent quality of welds, meet the requirements of precision instrument valves.
3. Unlike other bulky and oversized valves that take up too much space, our valves and fittings are compact in design and easy to operate.
4. What you see in our product pictures is exactly what you receive-the true embodiment of high-quality technology.
5. 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.
6. The machining workshop independently produces valve bodies, joints and other parts, and the quality is controllable.Wofly 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.
