The Stellar Industries 13731 Valve Assembly is a replacement low-pressure intake valve for compatible Champion R40 and R70 reciprocating compressor pumps used on Stellar and American Eagle equipment.
During the compressor’s intake stroke, this valve allows air to enter the low-pressure cylinder. It then closes during compression to prevent air from flowing backward. Replacing a worn or damaged valve helps restore air output, pressure buildup, and efficient compressor operation.
What This Part Is Used For
The Stellar 13731 valve controls incoming air at the low-pressure stage of compatible R40 and R70 compressor pumps. Proper sealing allows the piston to compress and transfer air through the remaining stages without excessive leakage or backflow.
Common Reasons For Replacement
Compressor builds pressure slowly
Air output or CFM has decreased
Compressor cannot reach operating pressure
Air flows backward through the intake
Low-pressure cylinder runs excessively hot
Valve is cracked, warped, or carbon-fouled
Valve does not seat or seal correctly
Unusual tapping or fluttering comes from the cylinder head
