Solenoid Valves for Automation
2/2 way - Normally Closed - Diaphragm pilot operated Fittings: G = 3/4” - 2”
General description:
PARKER series 133CMV solenoid valves
are diaphragm pilot operated and require a
minimum differential pressure to operate.
They are used for 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 133 valves are normally closed.
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” for maximum working temperature +140°C.
The maximum ambient temperature is:
•with class “F” coils +50°C
•with class “H” coils +80°C
Manual control:
The manual control is used to open the
valve without supplying voltage to the coil.
The control consists of a slotted-head
screw for a screwdriver with two possible
positions:
CLOSED valve closed
OPEN valve open
In the closed position the valve functions
normally when coil is energised.
Coils:
For series 133 valves class “F” coils
(155°C), encapsulated in thermoplastic
containing 30% glass fiber (types: ZB), are
available.
All the coils are for continuous service,
100% E.D.
The rated voltage tolerance is:
±10% for A.C. power supply and +10% -
5% for D.C.
The coils can be used on a.c.
