this control opens the electrical circuit when internal system pressures reach 610 PSI and resets automatically when pressure drops to 420 PSI

It is critical to match the coil amperage and voltage ratings

The unit is driven by a 3008D pneumatic actuator

Improved Signal Stability: Minimizes signal drift and provides a consistent flame detector infrared cell response for precise flame-out detection

Economizer Integration: Essential for determining free-cooling operational modes in commercial economizers

Sporlan 903024P Valve 320788-702 this control opens the electricalThe Sporlan 903024P, also identified as the LAC 4 180, is a heavy duty, non adjustable head pressure control valve designed to maintain consistent system performance during low ambient conditions. This three way low ambient control operates by restricting liquid flow from the condenser to the receiver while simultaneously diverting hot gas to the receiver inlet. This process effectively backs up liquid refrigerant into the condenser, reducing its
