Frequently asked questions
Does this valve integrate easily into my compressor setup?
Yes, the RPI CMV123 is designed as a direct replacement part, ensuring seamless integration. It comes as a complete kit including the main unloader valve and two RPF662 male connector fittings, making the replacement process straightforward.
Is the valve built for long-term reliability?
Absolutely. This valve features a robust aluminum body specifically engineered to withstand the demanding conditions and constant pressure cycles typical of dental equipment environments.
Can I use this with specific MDT McKesson desiccant tanks?
Yes, this valve is precisely compatible with MDT McKesson Desiccant Tanks identified by part numbers 3-08-0729-20 and 3-08-0800-30.
Are all necessary ports standard for quick exhaust?
The valve is equipped with three 1/4” Female Pipe Thread (FPT) ports, which is a standard configuration designed to provide efficient and reliable quick exhaust functionality for your dental compressor.
Is there a repair kit available for future maintenance?
Yes, we offer a dedicated Unloader Valve Repair Kit (CMK124) separately to help you maintain your valve’s performance over the long term without needing to replace the entire unit.
What additional supplies do I need for installation?
While the kit includes the valve and fittings, successful installation requires standard technical maintenance supplies. We recommend having 1/4” Teflon thread sealing tape (RPT579) on hand to ensure a secure, airtight seal during assembly.

Yes, the RPI CMV123 is a precision-engineered replacement that directly cross-references OEM Part #3-08-0308-10, ensuring you get the exact specifications required for your specific compressor model.
Is the valve easy to silence during operation?
For noise reduction and optimal exhaust flow, you can pair this valve with our separately available Purge Muffler (CMM017), which is designed to work seamlessly with this system.
Is this component factory new?
Yes, the RPI CMV123 is a factory-new replacement part, ensuring you receive a high-quality component free from the wear and tear associated with refurbished items.
Does it include all required fittings for the connection?
Yes, the kit is all-inclusive and arrives with the main unloader valve and two (2) Male Connector Fittings (RPI Part #RPF662), ensuring you have the necessary hardware for installation right out of the box.
