Pneumatic knife gate valve, DC channel full circle type residue does not exist, not blocked. The bottom end of the knife plate is processed into a knife edge, and it has the function of cutting off the soft and boring, such as fiber, pulp and wood pulp, and also has good khaki and closing functions. The best sealing effect can be obtained by the selection of stainless steel and fine grinding and polishing for the material of the valve plate. It has compact design, small occupying space, light weight, easy installation, wearable and anti blocking measures, convenient maintenance, convenient operation and long service life, and can choose any driving device at will.

1. Pneumatic knife gate valve is made into two forms of concealed pole and exposed pole according to different caliber (concealed pole, exposed pole). The full round DC channel is designed to be free of slag and jamming. The bottom end of the knife plate is processed into a blade shape, which has the cutting function for soft materials such as fiber, pulp and wood pulp, and has the good opening and closing function at the same time.

2. A hard polytetrafluoroethylene mud scraper is installed on the upper end of the knife plate, which can prevent dust, grit and other abrading substances from entering the stuffing box, and can significantly improve the life of the knife plate. The valve plate is made of stainless steel and polished to obtain the best sealing effect. Compact design, small occupation space, light weight, low price, easy to install, perfect wear-resistant and anti blocking measures, easy to maintain, easy to use and long life, and optional drive device.

3. The valve body and packing culvert of pneumatic knife gate valve are all precision casting, wherein the valve body is flange type integral casting, and the material can be 304, 316, 316L, WCB and 2Crl3 according to the user’s needs. The sealing ring is made of PTFE reinforced polytetrafluoroethylene, which is corrosion-resistant, wear-resistant and slag free. Performance specification
