The SV201 and SV202 are direct-lift
valves, which combine the features
of a direct-acting valve with those of
a pilot-operated valve. Because of a
flexible link between the solenoid
plunger and the diaphragm, the
direct-lift valve functions as a directacting
valve at low pressures and as
a pilot-operated valve at high
pressures. It is sometimes referred
to as a zero delta pressure valve or
a hung diaphragm valve.
The SV203 through SV207 are pilotoperated
solenoid valves. These
valves use the energy stored in the
pressurized fluid to actuate the
valving mechanism. They require the minimum pressure differential
specified for proper valve operation.
A direct-acting, normally closed
solenoid valve is an integral part of
the pilot-operated valve and is used
to affect the balance of pressure
above and below a diaphragm
or piston.
