5.1 Pressure reducing valve
On the side of the valve outlet, the pressure acts via the diaphragm on the
adjustable spring. A balance of forces is established via the spring preload, which is
set with the adjusting screw at the valve. If the outlet pressure increases above the
specified value, the piston is lifted against the spring resistance. The valve closes,
and the outlet pressure is reduced. If the outlet pressure decreases below the value,
the piston is pushed down by the spring resistance. The valve begins to open, until
the balance is reached again. Independent of an increasing or decreasing inlet
pressure, the outlet pressure remains constant to the greatest possible extent,
because it is not directly related to the inlet pressure.
