2/2 way - Normally Open - Direct Operated Fittings: G = 1/8” - 1/4”
General description:
PARKER series 120.4 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 120.4 valves are normally open with
inlet and outlet in line.
Temperatures:
The working temperature for media is:
maximum +160°C
minimum -30°C
The maximum ambient temperature is:
+60°C
Application:
Series 120.4 solenoid valves are ideal for
automatic control of fuel oils up to 7°E on
pressurised burners.
Coils:
For series 120.4 valves class “F” coils
(155°C) are available encapsulated in thermoplastic
containing 30% glass fiber
(types: ZB, YB) and class “H” coils (180°C)
are available encapsulated in thermoplastic
containing 40% 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
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.
