Lennox 35K71 Combustion Chamber R-407C this valve is perfect for

this valve is perfect for non-corrosive refrigerants and is NAVSEA certified

Field Adjustable: The threaded arm allows for precise positioning of weights to calibrate the opening point based on the system’s total external static pressure

is required to compensate for thinner air and ensure the induced draft motor creates sufficient vacuum for safe ignition

which is essential for sensing the actual pressure at the evaporator outlet to maintain accurate superheat

Common indicators include hunting (fluctuating suction pressure)
