pneumatic cylinder actuated knife type gate valve

Pneumatic cylinder actuated knife gate valve consists of one stainless steel/ductile iron knife gate valve and one pneumatic cylinder actuator. There is one blade-shape valve disc at the bottom of the knife gate valve, which has a high shearing effect and can prevent the knife gate valve from being blocked. The adhesive on the sealing surfaces can be removed automatically. Pneumatic cylinder actuated knife gate valve is suitable to open and closing the circulation of fluids which are difficult to control, such as slurry, powder, and fibers. 

The pneumatic cylinder actuated knife gate valve is usually used for working condition with working pressure lower than 1.0Mpa, and temperature less than 120℃. special material can be used for the pneumatic cylinder actuated knife gate valve, which can make that knife gate valve to be used for high temperature conditions. 

Pneumatic cylinder actuated knife gate valve is widely used in paper making, petrochemical, mining, waste water and food industries. The pneumatic cylinder actuator of pneumatic cylinder actuated knife gate valve can be changed into electric actuator according to the real working requirements, to realize the automatic operation. 

Performance advantages of pneumatic cylinder actuated knife gate valve: 

1. Pneumatic cylinder actuated knife gate valve is using the wafer end connect structure, which is small in size, light in weight, the channel of the pneumatic cylinder actuated knife gate valve is fully open, which can prevent the medium from accumulating on the valve sealing surfaces. 
2. During the opening and closing of the pneumatic cylinder actuated knife gate valve, the valve plate and sealing surfaces are specially designed, which is durable and has low friction. 
3. The upper sealing part of the pneumatic cylinder actuated knife gate valve adopts the upper cover structure. The large-area rectangular sealing of the upper sealing part is changed into small-area circumferential sealing, which can greatly improve the sealing performance of the pneumatic cylinder actuated knife gate valve. 
4. The pneumatic cylinder actuated knife gate valve can work as a blade, which can effectively cut off the medium flow and block the various sundries in the medium. 

Where pneumatic cylinder actuated knife gate valve is used? 

Pneumatic cylinder actuated knife gate valve is a more complex automatic control device, which is composed of various pneumatic components and knife gate valve body. Pneumatic cylinder actuated knife gate valve is usually used for working conditions which requires fast cutting-off and opening-up. 

Pneumatic cylinder actuated knife gate valve can be used for special media pipelines, like syrup, pulp and paper, sewage, coal slurry, ash, dust and water slag. Pneumatic cylinder actuated knife gate valve is suitable for horizontal installation and variable tilt installation.
