General description:
Coils:
PARKER series 174 solenoid valves have
direct action and therefore do not require a
minimum differential pressure to operate.
They are used for general applications,
when small overall dimensions and low
consumption are required, with media such
as water, air, light oils (2°E) and inert
gases, provided they are compatible with
the construction materials used.
Series 174 valves are normally closed.
For large orders, valves are available on
request with manual operator.
For series 174 valves the WB class “F” coil
(155°C), encapsulated in thermoplastic
containing 30% glass fiber, is used.
The coil is for continuous service, 100%
E.D.
The rated voltage tolerance is:
±10% for A.C. power supply and
+10% -5% for D.C.
The “W” coil can be used on a.c. with frequency of 50/60Hz (dualfrequency) and has
Faston terminals for DIN 43650B connectors with protection to IP65.
Temperatures:
Installation:
The working temperature for media is:
maximum
+140°C
minimum
-10°C
The maximum ambient temperature is:
+50°C
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 series 174 valves with the code .4 are
fitted with M4 x 7 mounting holes on the
valve body with centre distance 18 x 18 mm.

Series 174 solenoid valves are ideal for the
automatic control of media with low flow
rates.
Some typical application examples:
•Espresso coffee machines;
•Sterilisers;
•Compressed air systems;
•Welding machines;
•Wood-working machines;
•Electrical medical equipment;
•Shoe-manufacturing machines.
Approvals:
• Coil certification:
WB 4,5 115V/50-60Hz, 220-230V/5060Hz
• For the coil:
WB 4,5 115V/50-60Hz, 220-230V/5060Hz
• UL Recognized Comp. Mark for the coil:
WB 4,5 24V/60Hz, 110-120V/60Hz, 208-240V/60Hz
Special versions:
On request and for large orders, the series
174 can be fitted with quick action coupling
fittings such as Prestolock cartridge.
