Air Compressor Unloader Valve - Replacement For Speed Air/MI-T-M 22-0270, 1/2 Inch 45 Degree

About This Product

So if you're dealing with air compressor issues, this combination unloader pilot check valve might be exactly what you need. It's a direct replacement for Speed Air and MI-T-M part number 22-0270, designed for 6.5HP gas engines and below. The valve has a 1/2 inch 45-degree male flare inlet and a 1/2 inch male NPT outlet, preset for 140-175 PSI operation. What's cool about this is it's an all-in-one unit that combines a pilot valve, discharge unloader valve, AND check valve - so it handles multiple functions that would normally require separate components. The unloader valve has a 30 CFM flow rate with a pressure differential of 10 to 50 PSI, and it can handle temperatures from -65??F to 400??F. There's a manual hand unloader toggle and brass venting muffler included too. Maximum operating pressure is 500 PSI with a minimum of 80 PSI. The way it works is pretty clever - the check valve prevents backflow while the compressor builds pressure, then when downstream pressure hits the unload setting, the pilot opens and pressurizes the unloader valve to vent excess air. As pressure drops to the load setting, the cycle repeats. It's made in the USA, which is nice to see for industrial components like this. Whether you're repairing an existing compressor or building a custom air system, this combination valve simplifies the plumbing and provides reliable continuous operation for your air tools and equipment.
