2/2 way - Normally Closed - Direct Operated
Fittings: G = 1/8” - 1/4”
General description:
PARKER series 140 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 fuel oils, diesel oil or naphtha
up to 7°E, provided they are compatible
with the construction materials used.
Series 140 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 solenoid valves are ideal for
automatic and safe control of fuel oils up to
7°E on pressurised burners.
Coils:
For the series 140 class “F”coils (155°C)
are available encapsulated in thermoplastic
material containing 30% glass fiber (types:
ZB, YB), and class “H” coils (180°C) 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% in 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 connector with protection to IP65.
The “Y” coil has terminals with 2 x 1,000
mm cable and protection to IP67.
The “X” coils has Faston terminals for plug
with cable (box) with protection to IP54.
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.
The model 140.4 has no mounting hole.
