Hands Down Superior Sound!

Our Instrument Innovations Rotary Valves play more open than traditional rotary valves without the extra wind required by axial flows valves.  

Our ball bearing technology allows lightning fast, smooth, and quiet operation.  Our rotor rides between bearings, which eliminates the abrasion that causes the valve to lose its seal.

The pressure releases at half stroke with our venting system, which is only possible because of our precision machining. No lapping required!

Our valve can be actuated from either side!

Ferrules available in a separate listing.

We offer a one time set of "dummy" side plates to techs for conversions.  Our bearings must not be exposed to the heat of solder/braze.  Please let us know who your tech is so we can add these to your order if your tech has not done a conversion with our rotary valves yet.

We recomment using Berp Light Valve BioOil for cleaning your valve and preventing corrosion, which we also offer.
