United Electric J21K-16020 Pressure Switch R-410A making it ideal for controllingThe United Electric J21K 16020 is a heavy duty differential pressure switch designed for critical monitoring in industrial HVACR systems, chillers, and compressor circuits. Featuring an adjustable setpoint range of 1 to 15 PSID, this unit utilizes an opposing sealed metal bellows design to detect precise pressure deviations between two points. This mechanical accuracy is essential for filter status monitoring and verifying proof of flow in hydronic or
