WAFER TYPE UNIDIRECTIONAL PNEUMATIC KNIFE GATE VALVE

The wafer-type pneumatic one-way knife gate valve, also known as a gate or sluice gate, is suitable for liquids containing a maximum of 5% suspended solids. If used for gravity discharge of dry solids, it is recommended to install it with the arrow on the body pointing away from the flow direction.

Applications: paper industry, mining, wastewater treatment, chemical plants, food industry, pumping, silo unloading, etc.
