The ELGi Compressor Intake Valve Kit (also known as the Unloader Valve Kit) is a specialized maintenance package designed to restore the precision control of the air intake process in EG and EN series rotary screw compressors. The intake valve is the "gatekeeper" of the system, modulating the airflow into the screw element to switch the machine between load and unload states. This genuine kit contains all critical wear components—including high-temperature O-rings, specialized seals, springs, and pistons—required to ensure the valve opens and closes smoothly. By performing regular overhauls with this kit, you prevent common issues such as air back-pressure leaks, sluggish loading, and excessive energy consumption, ensuring the compressor responds accurately to system demand while maintaining peak volumetric efficiency.
