Pneumatic knife gate valve is a type of valve that uses pneumatic actuators to control the valve and achieve the opening and closing of the valve. It can be divided into two parts: the upper part is a piston type pneumatic actuator, and the lower part is a knife type gate valve.

 

The pneumatic knife type gate valve has the advantages of simple and compact structure, reasonable design, lightweight and material saving, reliable sealing, light and flexible operation, small volume, smooth channel, small flow resistance, light weight, easy installation, and easy disassembly. It can work normally under working pressure Class 150 (1.0MPa-2.5MPa) and operating temperature of -29-650 . The blade gate valve has a shearing function on its gate plate, which can scrape off the adhesive on the sealing surface and automatically remove debris. The stainless steel gate plate can prevent sealing leakage caused by corrosion.

 

1. Pneumatic knife type gate valves are made into two forms according to different calibers: concealed and exposed. The full circular DC channel design is free of slag and blockage. The bottom end of the blade is processed into a blade shape, which has a cutting function for soft materials such as fibers, pulp, and wood pulp, and has good opening and closing effects. A hard polytetrafluoroethylene scraper is installed on the upper end of the blade to prevent abrasive substances such as dust and gravel from entering the packing box, which can significantly improve the lifespan of the blade. The valve plate material is made of stainless steel and finely polished to achieve the best sealing effect. Compact design, small space occupation, light weight, affordable price, easy installation, complete wear-resistant and anti blocking measures, easy maintenance, convenient use and long service life, and the drive device can be freely selected.

2. The valve body and packing culvert are all precision cast, with the valve body using flange integral casting. The material can be selected as 304, 316, 316L according to user needs WCB2Crl3The sealing ring is made of PTFE reinforced polytetrafluoroethylene material, which is corrosion-resistant, wear-resistant, and free of slag.

3. The valve plate has 5 support points to ensure good self alignment. When the valve is in the closed state and subjected to back pressure, the valve plate does not shift.

4. The internal of the pneumatic knife gate valve can be made into V-shaped, triangular, and pentagonal channels. The V-shaped gate can be used as a regulating control.

5. The connection forms of pneumatic knife type gate valves include clamp type and flange supported ear type, with metal to metal hard seal, metal to polyurethane, and reinforced PTFE soft seal.

6. Applicable media: gold powder, tailings, pulp, wood pulp, fiber, dust, chemical treatment wastewater, sedimentation tank, sand, slag, coal slurry, asphalt, silo outlet, fruits, grains, cement slurry, slaughterhouse wastewater, etc.
