Do screw air compressors have solenoid valves at the inlet? Do these solenoid valves close during unloading? Then the solenoid valve closes, the air compressor continues to run – won’t the inlet of the housing be under negative pressure? Or in other words, can the air compressor still rotate with the inlet solenoid valve closed?
Generally, for units like Atlas, the valves are either fully open or fully closed; there are exceptions however – units from GD and Ingersoll Rand have a 15% adjustment range. When the unit is unloaded, the solenoid valves close, and of course the inlet valve also closes. But the valves are designed with small holes to prevent vacuum formation when the unit is unloaded, so you can use them with confidence without any risk of vacuum formation
LS has put it very well. Solenoid valves are generally used to control large valves, which are usually butterfly valves that operate in a fully open or fully closed state. However, these valves have small holes, so they aren’t completely closed; when the system is in a unloaded state, the unit operates with little load
During shutdown, the intake valve closes and the compressor operates without load, similar to the neutral state of a car
The inlet valve of the air compressor during unloading is fully closed; by \"fully closed\" it is meant either the fully closed position indicated by the indicator or that set on the control panel. In reality, however, the valve is still slightly open
What is the function of the gas coming out of the solenoid valve outlet?
