2.7 Operation
Logic
As supply pressure from regulator is connected to supply port and signal pressure is
connected to supply port, upper diaphragm (
○

) and diaphragm assembly will get pushed
down. As they are being pushed down, they push stem and supply pressure will be
exhausted to output port. As output and supply pressure is equalized, stem will be moved
to keep signal and output pressure the ratio of 1:1. If output pressure is higher than signal
pressure, diaphragm assembly will be raised, and output pressure in the exhaust ring (
○

)
will be exhausted through exhaust port. The sensitivity of output pressure to signal
pressure can be adjusted by setting adjust bolt (

).
