21A3KT30直動膜片式電磁閥ODE**特點  的詳細介紹

21A3KT30直動膜片式電磁閥ODE**特點
For a correct operation of the solenoid valve, and to avoid
a quick wear of the diaphragm, it is advisable that, once
starting the valve closing, the actual flow isn’t higher than the Kv (i.e.: flow rate through the
valve with a pressure loss of 1 bar).
For this reason, should the inlet pressure when the valve is open, be higher than 1 bar, it is
not advisable the use of the valve itself with free outlet, i.e. without an outlet restriction bringing the pressure drop to the value of 1 bar.
Moreover, particular attention must be paid in designing the hydraulic circuit to the problem
of water hammering which could cause overpressures such as to lacerate the diaphragm or
damage other parts of the solenoid valve.

In this family of solenoid valves there must be a minimum
pressure difference between the inlet and outlet pipes to
ensure correct functioning of the solenoid valve.
However, an excessive pressure difference between inlet
and outlet, as with 2 way normally open direct acting solenoid valves, causes an increase in the force required to
open the pilot orifice, so if this pressure difference is
greater than the maximum value for which the solenoid
valve has been designed, the latter may not reopen even
when the coil is not energized.

2 way normally open solenoid valves with pilot control have an inlet pipe and a outlet pipe.
Functioning of these solenoid valves is, as regards movement of the diaphragm, identical to that of 2 way normally
closed solenoid valves with pilot control except that in
place of the normally closed kit a normally open kit is
mounted to open and close the pilot orifice. So in this case
with the coil energized the pilot orifice is closed and the
diaphragm therefore in such a position as to close the main
orifice, whereas with the coil not energized the pilot orifice
is open, thus cau-sing the main orifice to open.
