High Starting Torque: The HST motor ensures consistent performance in systems using expansion valves or capillary tubes where unbalanced pressures are common during startup

making it suitable for high-demand swimming pool heaters and commercial boilers

It features a displacement of approximately 12

ensuring that the furnace collector box aligns perfectly with the inducer motor and secondary heat exchanger ports

Key Benefits for the Jobsite Precise Thermal Calibration: Opens at 185°F and resets at 155°F to prevent heat exchanger fatigue

Sporlan 903106P Valve R-410A High Starting Torque: The HSTThe Sporlan 903106P, also identified as the LAC 10 295HP, is a heavy duty head pressure control valve engineered for consistent refrigerant flow in low ambient conditions. This three way modulating valve responds directly to receiver pressure, utilizing a 295 PSI factory setting to bypass the condenser when pressures drop below the setpoint. By diverting discharge gas to the receiver and flooding the condenser, it effectively maintains the necessary
