2/2 way - Normally Closed - Diaphragm pilot operated
Fittings: G = 3/8” - 1”
General description:
PARKER series 135 solenoid valves are
diaphragm pilot operated and therefore
require a minimum differential pressure to
operate.
They are used for steam and superheated
water.
Electrical components are insulated from
the moving parts in contact with the media
and therefore series 135 valves are particularly
suitable for demanding applications.
Series 135 valves are normally closed.
Temperatures:
The working temperature for media is:
maximum +180°C
minimum -30°C
The maximum ambient temperature is:
+80°C
Coils:
For series 135 valves class “F” coils
(155°C) are available encapsulated in thermoplastic
containing 40% of glass fiber
(types ZH).
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” coil can be used on a.c. with a frequency
of 50/60 Hz (dual frequency) and
has Faston terminals for DIN 43650A connectors
with protection to IP65.
Application:
Series 135 solenoid valves are ideal for
automatic control of steam and superheated
water in a wide range of applications
such as those listed below.
• Dry-cleaning systems;
• Steam generators;
• Laundry systems;
• Sterilisers;
• Autoclaves;
• Plant food industry;
• Steam presses;
• Drying systems;
• Catering systems.
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.
