2/2 way - Normally Closed - Direct Operated
Fittings: G = 1/8”
General description:
PARKER series 140.2 solenoid valves are
direct operated and do not require a minimum
differential pressure to operate.
They are used for general applications with
media such as steam and superheated
water.
Series 140.2 valves are normally closed.
Temperatures:
The working temperature for media is:
maximum +140°C
minimum -30°C
The maximum ambient temperature is:
with class “F” coils +50°C
with class “H” coils +80°C
Application:
Series 140.2 solenoid valves are
particularly suitable for small flow rates of
steam or superheated water.
Some typical application examples:
• Espresso coffee machines;
• Automatic dispensers;
• Sterilisers;
• Autoclaves.
Coils:
For series 140.2 valves class “F” coils
(155°C) are available encapsulated in thermoplastic
containing 30% glass fiber
(types: ZB, YB) and class “H” coils (180°C)
series are available encapsulated in thermoplastic
material containing 40% of glass
fiber (type ZH).
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.
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.
