Solid-State Reliability: Eliminates moving mechanical parts within the ignition sequence

The inclusion of manual reset functionality requires a technician to investigate the root cause of the oil pressure drop before restarting the system

While optimized for 36E series valves

it features silver contacts and rugged terminals to ensure long-term electrical conductivity and consistent thermal sensing performance under high ambient temperatures

Where should the atmospheric vent be directed

Johnson Controls P72LB-1 Pressure Control THPU32HP7Y Solid-State Reliability: Eliminates moving mechanicalThe Johnson Controls P72LB 1 is a robust dual pressure control designed for heavy duty commercial refrigeration and HVAC applications. Featuring a DPST (Double Pole Single Throw) switch mechanism, this all range pressure switch provides direct individual control of single phase motors up to 3 hp and three phase motors up to 5 hp, eliminating the need for separate contactors in many setups. The low pressure side handles a range of 20" Wc to 100 psi
