Drain, Blowdown, and Purge Valves for Air Compressors
Drain, blowdown, and purge valves are used in compressed air systems to release condensate, excess air, or internal pressure at specific stages of operation. These valves support proper system performance, protect components, and help manage moisture and pressure within the compressor.
Blowdown and purge valves are commonly used during shutdown or unloading cycles to relieve internal pressure and reduce load on the motor during restart. Drain valves are used to remove collected condensate from compressors, dryers, and air receivers to prevent moisture accumulation within the system.
These valves may operate mechanically, pneumatically, or electrically depending on system design and control strategy. Drain, blowdown, and purge valves are commonly found in rotary screw compressors, air dryers, and associated compressed air equipment.
