General description:
Coils:
PARKER series 128 solenoid valves are
direct operated and do not require a minimum differential pressure to operate.
They are used for superheated water.
Series 128 valves are normally closed.
The inlet and outlet fittings are situated on
the mounting flange and enclosing tube.
For series 128 valves class “F” coils
(155°C) are available encapsulated in thermoplastic containing 30% glass fiber, (ZB,
YB types). Class “H” coils (180°C) are available encapsulated in thermoplastic containing 40% of glass fiber ( ZH type).
All the coils are for continuous service,
100% E.D.
The rated voltage tolerance is:
±10% for A.C. power supply and
+10% -5% for D.C.
The “Z” and “Y” coils can be used on a.c.
with a frequency of 50/60 Hz (dualfrequency).
The “Z” coils have Faston terminals for DIN
43650A connectors with protection to IP65.
The “Y” coil has terminals with 2 x 1,000
mm cables with protection to IP67.

minimum
-10°C (FKM)
The maximum ambient temperature is:
• with class “F” coils
+50°C
• with class “H” coils
+80°C
Application:
Series 128 solenoid valves are ideal for
automatic control of superheated water for
dispensing espresso coffee.
Models are available with various seals and
fitting configurations for maximum
flexibility of application and installation.
Some typical application examples:
• Espresso coffee machines, for bars;
• Espresso coffee machines, for the home;
• Automatic dispensers.
Installation:
The valves can be mounted in any position
without jeopardising their operation. It is
however advisable to install them with the
coil in a vertical position above the body.
