The SV230 Series valves are designed
for low-pressure steam applications in
which the valve must operate when
the pressure drop across the valve
falls into the 0 to 5 psi range. These
valves are able to control steam up to
45 psi at 143ºC (290ºF). All seals are
made of ethylene propylene for
compatibility with steam over a wide
temperature range and for trouble-free,
bubble-tight service.
The SV231 through SV235 are direct-lift
valves, which combine the features of a
direct-acting valve with those of a pilotoperated
valve. Because of a flexible
link between the solenoid plunger and
the diaphragm, the direct-lift valve
functions as a direct-acting 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.
