Siemens Industrial Controls 40-7 Pressure Regulator 6-200" H20

The Siemens Industrial Controls 40-7 Pressure Regulator is a modulation unit that is aimed at the maintenance of controlled air or gas pressures in the HVAC systems. The regulator controls the inlet pressure and changes the internal diaphragm and spring assembly to maintain a constant range of outlet between 6 and 200 inches of water column. The mechanism matches the force on the sensing element to stabilize the downstream flow conditions. It aids in the controlled pressure, prevents oscillation of related elements, and ensures the stability of system reaction to the different load levels.
