2/2 way - Normally Closed - Diaphragm pilot operated Fittings: G = 3/8” - 2”
General description:
PARKER series 133H solenoid valves are
diaphragm pilot operated and require a
minimum differential pressure to operate.
They are used for steam and superheated
water where high flow rates are required.
Series 133H valves are normally closed.
Temperatures:
The working temperature for media is:
maximum +140°C
minimum -10°C
The maximum ambient temperature is:
• with coils in class “F” +50°C
• with coils in class “H” +80°C
Application:
Series 133 H solenoid valves are ideal for
the automatic control of high temperature
water and steam.
Some typical application examples:
• Steam generators;
• Sterilisation systems;
• Industrial washing machines;
• Washing systems;
• Furnaces;
• Boiling systems;
• Autoclaves.
Coils:
For series 133H 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% of glass fiber (ZH type).
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 “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.
