Torex rotary valves from WAM Australia are part of a comprehensive range of flexible solutions for diverse pneumatic conveying and bulk handling requirements.

Rotary valves are designed for controlled feeding from or into silos and hoppers in confined space applications. The sealing of negative pressure cyclone and dust filter outlets is the other classic application.

Consisting 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, rotary valves feature a robust and compact design with easy access to all internal mechanical components.

Two compartments of the continuously turning rotor are filled up with material at a time 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 valve with square inlet and RVR with a circular inlet consist of a tubular cast iron or stainless steel casing.

Torex rotary valves are compatible with other WAM Group equipment thanks to WAM standard flanges. The rotary valves are available with various accessories and optional features to meet individual requirements.
