an additional step-down regulator is required to prevent damage to the internal diaphragm
this FNPT check valve is built to withstand the rigorous pressure and thermal fluctuations common in commercial and industrial piping arrays
making it less susceptible to the thermal shock and mechanical vibration that often leads to premature failures in standard 120V ignition systems
the 316203A and the 316203A/U are the same physical component
Using genuine HVAC replacement parts is the only way to satisfy original equipment specifications and maintain the integrity of the furnace control system in high-efficiency mobile home or residential units
Belimo NMQB24-MFT Actuator 30067439-890 an additional step-down regulator isThe Belimo NMQB24 MFT Actuator is a non spring return, high speed solution designed for precise proportional damper control in commercial HVAC systems. Delivering a steady 70 in lb torque, this multifunction technology (MFT) actuator offers field programmable flexibility via 24Vac dc power. It natively supports a 2 10Vdc control signal, but remains adaptable for 4 20mA modulation (using a 500 Ohm resistor), PWM (1500 Ohm), and floating point or on off
