Stellar Industries 13733 High-Pressure Intake Valve Assembly for Champion R40/R7

If you’re unsure whether this part is compatible with your truck or equipment, please contact us to confirm fitment before purchasing.

The Stellar Industries 13733 Valve Assembly is a replacement high-pressure intake valve for compatible Champion R40 and R70 reciprocating compressor pumps used on Stellar and American Eagle equipment.

The valve controls airflow entering the compressor’s high-pressure cylinder. It opens during the intake stroke and closes during compression to prevent air from flowing backward. Replacing a worn valve helps restore pressure buildup, air delivery, and efficient two-stage compressor operation.

What This Part Is Used For

The Stellar 13733 valve receives compressed air from the low-pressure stage and admits it into the high-pressure cylinder for final compression. Proper valve sealing is necessary for the compressor to reach its rated operating pressure efficiently.

Common Reasons For Replacement

Compressor builds pressure slowly
Compressor cannot reach maximum operating pressure
Air output has decreased
Air flows backward between compression stages
High-pressure cylinder operates excessively hot
Valve is cracked, warped, or carbon-fouled
Valve does not seat or seal correctly
Tapping or fluttering comes from the compressor head
