2/2 way - Normally Open - Diaphragm pilot operated Fittings: G = 3/8” - 3”
General description:
PARKER series 143 solenoid valves are
diaphragm pilot operated and require a
minimum differential pressure to operate.
They are used for general applications with
high flow rates and media such as water,
light oils (2°E) and others, provided they are
compatible with the construction materials
used.
Series 143 valves are normally open.
Temperatures:
The working temperature for media is:
maximum +90°C
minimum -10°C
with NBR seals (Buna N).
On request seals in Viton are available for
fittings < G 1” and maximum working temperature+ 140°C.
The maximum ambient temperature is;
• with class “F” coils +50°C
• with class “H” coils +80°C
Application:
Series 143 solenoid valves are ideal for the
automatic control of media in a wide
range of applications such as:
•Thermohydraulic systems;
•Air compressors;
•Washing plants;
•Hydrocleaners.
For air and inert gases they can be used
for low operating frequencies.
