Synthetic reinforcement significantly reduces belt stretch
leading to weak sparks and ignition failure
its robust construction is designed to handle the static pressure typical of commercial VAV box and multi-zone air distribution systems
ensuring the valve stem remains securely sealed without increasing mechanical friction that could lead to actuator hysteresis
This pilot safety sensor is engineered to generate the necessary voltage to hold the gas valve solenoid open under standard operating temperatures
Lennox 57M67 Pressure Switch Synthetic reinforcement significantly reduces beltThe Lennox 57M67 Pressure Switch is a high precision OEM component engineered for critical safety monitoring in gas fired furnaces and HVAC systems. As a veteran technician knows, maintaining the correct pressure threshold is vital for inducer motor verification and combustion safety. This SPST pressure switch is factory calibrated to actuate at 1. 71" WC (water column), ensuring that the exhaust blower is moving sufficient air before the ignition
