MORE INFORMATION

BASIC DESIGN

The Cheminert design involves a flat rotor which is engraved with slots to connect the ports and a stator which is held against the rotor at a constant, preset force.

When repairs are required, just take out two or three screws, replace the rotor, and put the screws back in and tighten them. No adjustments are possible, much less required. Other advantages of the design include easy panel mounting, low actuating torque, and compact size.
