Knife Gate Valve with Flushing Port/Purge Ports Design
Often, knife gate valve applications have suspended matter that can build up in the chest and pocket cavities.
Severe build up can interfere with the normal operationof the valve.
Purge ports can keep this build up from happening by flushing the valve with liquid, gas, or in some cases,
steam. Purge ports are typically placed on the sides of the valve chest and bottom of the valve.
