Methodof Operation
Spring loadedpressure reducing valves operate bymeans of a
force equalising system. The force of a diaphragmoperates
against the force of an adjustment spring. If the outlet pressure
and therefore diaphragm force fall becausewater is drawn, the
then greater force of the spring causes the valve to open. The
outlet pressure then increases until the forces between the
diaphragm and the spring are equal again.
The inlet pressurehasno influence ineither openingor closingof
the valve. Because of this, inlet pressure fluctuation does not
influence theoutlet pressure, thusproviding inlet pressurebalan-
cing.
