Product Description

knife type gate valve has the advantages of simple and compact structure, reasonable design, light material, reliable sealing, light and flexible operation, small size, smooth passage, small flow resistance, light weight, easy installation and easy disassembly. The working pressure is 1.0MPa-2.5MPa, and the working temperature is normal when the temperature is -29-650°C. The knife-type gate valve has a shearing function, which can scrape off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate can prevent sealing leakage caused by corrosion.
