4. Operation
(Refer to the parts number in “3.2 Construction”)
Turning the adjusting screw(11) to compress the adjusting spring(17) and the load of adjusting
spring is introduced to the diaphragm(9) and suspension metal(7) to open the valve(4). Then,
the fluids begin to flow from the inlet side through the upper side of the valve. The reduced
pressure is led to the diaphragm to be balanced with the adjusting spring load, and control the
valve travel to maintain the reduced pressure.
