Operating and installation instructions
Pneumatic actuators - FA160-800
3.0 Storage and transport
- At -20°C to +65°C.
- Do not damage paint protection (the actuators should rest in the packing till installation).
4.0 Description
4.1 Scope of applications
The pneumatic actuators are used to operate the FABA-Supra valve ("open / close"
function only).
Please contact the supplier or the manufacturer if you have any questions.
4.2 Operating principles
By means of the pneumatic actuator units, pneumatic control signals are converted into a
translatory motion. The necessary restoring force is generated by means of the
compression springs on the bulk of the diaphragm plate.
In case of air fall-off, the actuator will be restored by means of the spring force in the
starting position.
The operating mode of the actuator is the following:
„spring closes“ (on air failure)
or
„spring opens“ (on air failure)
This operation is obtained and dependent on the assembly of the springs.
By using a rolling diaphragm, linear rod forces during long lifts can be obtained.
ATTENTION !
- Protect against external force (like impact, vibration, etc.).
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
- Suitable materials handling and lifting equipment
should be used.
Observe max. load-carrying capacity of the eye nuts (Fig. 1):
FA250 - FA400 = 100 kg
FA800 = 170 kg
(Refer to catalog sheet for weights)
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
