Description
The Johnson Controls P170KA-1C 4-Wire 2-Circuit Single Pressure Control 50–450 PSI is a pressure-sensing control component for monitoring and regulating fluid pressure to ensure safe and stable operation. It operates through an internal diaphragm mechanism that responds to pressure changes, opening or closing electrical contacts when preset limits are reached to manage system operations. Within HVAC systems, it is mounted on coolant lines or pressure points in compressors and refrigeration circuits where protection and control are required. It prevents overpressure conditions, improves equipment safety, supports operational stability, and ensures consistent performance in commercial and industrial operations.
