VALVES AND REGULATORS
The direct-acting SV121 to SV127 solenoid valves
consist of a coil, plunger, and sleeve assembly. In
a normally closed state, a plunger return spring
holds the plunger against the orifice, preventing
flow through the valve. When current flows through
the coil, a magnetic field is produced and it turns
the stop into an electromagnet that attracts the
magnetic plunger. This action compresses the
return spring, allows the body orifice to open, and
permits fluid flow through the valve. The pressure
and flow capabilities of the direct-acting valves are
limited by the power of the solenoid.
The SV128 is a pilot-operated solenoid valve.
It uses the energy stored in the pressurized fluid
to actuate the valving mechanism. The valves
require the minimum pressure differential specified
for proper valve operation. A direct-acting 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.
