Features:
Manual knife gate valve and a manual type knife gate valve, knife gate valve manually, driven by the handwheel, generally for small diameter valves, with compact structure, reasonable design, lightweight materials, sealing is reliable, flexible and convenient operation, small volume, smooth channel, small flow resistance, light weight, easy to install, easy to remove, etc, can be in work pressure 0.6 MPa to 2.5 MPa, in the case of temperature - 29-650 ℃ to work normally. Knife-type gate valve has the function of cutting the gate plate, which can scrape the adhesive on the sealing surface and automatically remove sundries. The stainless steel gate plate can prevent the sealing leakage caused by corrosion.
Application:
Knife gate valves have entered China since the 1980s. In less than two decades, its use has expanded from the general field to a wider range of industries. Coal preparation, ash removal and slag removal from mining and power plants. Urban sewage treatment, from the general industrial pipeline to the development of food, health, medicine and other professional pipeline system.
Ultra-thin knife gate valve with its small volume, small flow resistance, light weight, easy to install, easy to remove and other advantages of the general gate valve, plate gate valve, ball valve, globe valve, regulating valve, butterfly valve and other types of valve flow resistance, large weight, installation difficult, large area of trouble. After the appearance of knife gate valve, a large number of general cut-off valves and regulating valves have been replaced. To date, the world's largest use of knife gate valves is the United States and Japan.
