Abstract
An automatic vent valve for pneumatic control systems of compressors or the like allows a compressor to be shut down when the level of liquid in an associated gas scrubber reaches a certain level. The device is also applicable to pressure vessels, boilers or similar devices requiring level control. A pneumatic vent valve responds to float movement through a simplified direct-acting mechanism having a sealed shaft between the float and vent chambers.
