Frequently Asked Questions
What is the function of an oil stop/check valve in a compressor?
The oil stop/check valve blocks oil backflow during compressor shutdown, keeping oil within the circuit and preventing dry starts that lead to excessive wear.
Why is it important to use genuine Atlas Copco parts?
Atlas Copco engineers every genuine part to your compressor’s exact specifications, ensuring a perfect fit, peak performance, and maximum equipment lifespan. Using non-genuine parts can lead to decreased efficiency, increased maintenance costs, and potential damage to your compressor.

Is this kit compatible with all Atlas Copco oil-injected screw compressors?
While this kit is designed for oil-injected screw compressors, it’s crucial to verify compatibility with your specific compressor model. Always cross-reference the part number with your equipment’s documentation or contact Atlas Copco support.
What are the signs that my oil stop/check valve might need replacement?
Common signs include oil leaks, reduced compressor efficiency, increased oil consumption, or unusual noises during startup or shutdown. Prompt replacement can prevent more severe damage to your compressor.
