Price Guide: POA

When controlled feeding from or into silos and hoppers in a very confined space is required, Rotary Valves are the ideal solution. The sealing of negative pressure cyclone and dust filter outlets is the other classic application.

Rotary Valves consist of a tubular casing, a horizontally mounted rotor with a certain number of V-shaped cross section compartments, a drive unit and a casing cover opposite the drive end.

Two compartments at a time of the continuously turning rotor are filled up with material through the infeed opening at the top of the Rotary Valve. After less than half a turn the material falls through the outlet port with the same cross section opposite the inlet. RV Drop-Through Rotary Valves with square inlet and RVR with a circular inlet consist of a tubular cast iron or stainless steel casing.
