2/2 way - Normally Closed - Direct Operated
Fittings: Rp = 1/8” - 1/4”
General description:
PARKER series 161.4 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 steam and superheated
water.
Series 161.4 valves are normally closed.
Temperatures:
The working temperature for media is:
maximum +140°C
minimum -10°C
The maximum ambient temperature is:
+80°C
Application:
Series 161.4 solenoid valves are ideal for
automatic control of steam and superheated
water with low flow rates.
Some examples of typical applications:
• Espresso coffee machines;
• Sterilisers;
• Electrical medical equipment;
• Humidifiers.
Coils:
For series 161.4 valves class “F” coils
(155°C) are available encapsulated in thermoplastic
containing 30% heat-stabilised
glass fiber (type KT).
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 “K” coil can be used on a.c. with a frequency
of 50 Hz (single frequency) and has
Faston terminals for DIN 43650A connectors
with protection to IP65.
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.
