Get to Know About Rotary Valves

A rotary valve, also known as a rotary-motion valve, rotary airlocks, or rotary feeders, controls the flow of liquid or gas through the connected pipes by rotating one or more passageways in a transverse plug. The function of rotary valve is to meter the flow of granular bulk or powders. With small pressure loss, material enters the valve by a hopper or other inlets, processed by the valve rotor, and then deposited in discrete packets onto a conveyor system.

Purpose of Rotary Valves

The major purposes of rotary valves are:

  1. To offer an airlock (pressure seal) between two processes that are next to each other
  2. To provide solids metering (feeding)
  3. To provide a pressure seal and solids metering combined for feeding solids into a pneumatic conveying system.
