Stainless steel is a group of iron-based alloys that contain a minimum of approximately 11% chromium, a composition that prevents the iron from rusting and also provides heat-resistant properties. Weidouli not only manufactures exotic materials of plug valve, we are also producing stainless steel plug valve, which is commonly used for not very corrosive application.
Sizes DN200 and below are by investment to reduce machining process and expedite the delivery, which can meet with urgent need. In addition, Weidouli operates a big and dynamic inventory of stainless steel plug valves.
