Pneumatic Knife Gate Valve

Valvesonly achieves excellence in Pneumatic Knife Gate Valve Manufacturers in USA. It is a specialized Gate valve, used as a shutoff valve used in various industries. Mainly useful in isolating thick fluids, abrasive materials, waste water, slurries. It shuts off the flow for highly viscous liquids or liquids that have solid components in it.

Working and functions
A thin metal plate (knife) will be used to isolate the flow in a piping system, or a channel, which can be actuated manually using a handwheel or automatically – geared motor or pneumatic cylinder. In a Pneumatic Knife Gate valve, a pneumatic cylinder will be mounted on the upper part of the valve, when pressurized air is passed through a solenoid, it closes or opens the valve. It helps convert the compressed air pressure into a mechanical force, enabling the knife gate valve to close or open.

Advantages:
●Stable performance
●Convenient operation
●Larger lifting force, capable of withstanding opening torque
●Quick open-close function
●Easy transport, storing, installation and maintenance
