Minimum Pressure Check Valves for Air Compressors
Minimum pressure check valves are used in air compressor systems to maintain a required minimum system pressure while preventing reverse airflow. These valves help ensure proper compressor operation by holding pressure within the system during startup and normal operation.
In rotary screw air compressors, minimum pressure check valves support oil circulation, separator performance, and stable airflow by retaining pressure downstream of the compression element. At the same time, they function as check valves to prevent compressed air from flowing back toward the compressor.
Minimum pressure check valves operate automatically based on system pressure and do not rely on electrical or external control signals. Valve design, pressure setpoints, and connection styles vary depending on compressor model and application requirements.
Air Compressor Services offers OEM-equivalent minimum pressure check valves manufactured to meet original equipment specifications. All valves are designed to match original fit and performance requirements when selected by part number and application.
