The core components of the Atlas Copco air compressor's discharge valve kit
Typically include:
Main discharge valve body (controls the opening / closing of the intake passage)
Electromagnetic valve (receives signals from pressure switches and controls the discharge action)
Spring, seals (ensures pressure control accuracy and sealing)
Connection pipes or joints (fits with the air path design of different models)
Valve core / valve seat (the core sealing component, preventing leakage)
Application scenarios and functions
Pressure control: Combined with pressure sensors / switches, when the pressure in the storage tank reaches the upper limit, the discharge valve opens, causing the compressor to be in a standstill state and stop the output of compressed air.
Protection mechanism: In case of machine overload, overpressure, or shutdown, quickly discharge the pressure in the gas path to avoid damage to components due to continuous high pressure.
Energy-saving operation: In the discharge state, the power consumption of the compressor decreases, extending the equipment's lifespan.
Selection and replacement precautions
Model matching: It is necessary to select the original factory kit based on the specific model of the air compressor (such as GA, GX, ZR series, etc.) and its power. For example, models above GA37 have significant differences in the specifications of the discharge valve compared to small GX series.
Pressure range: Confirm the applicable working pressure of the kit (such as 0-10bar or 0-16bar), matching the machine's rated pressure.
Installation requirements:
Before replacement, release the residual pressure in the system
Clean the connection parts to avoid impurities entering the gas path
Seals need to be coated with special food-grade lubricating grease (if used in food industry air compressors)
