Hands Down Superior Sound!

Delivery will not be until end of year or first quarter.  Sorry for the inconvenience

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.

Please let us know which tech you are using for your conversion.  We offer a one time supply of "dummy" side plates for valve mounting.  Our bearings cannot be exposed to the heat of solder/braze.  These plates are reusable so the tech will have them for future conversions.

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