6.2.2 Installing actuator on valve housing
DANGER!
Risk of explosion if incorrect lubricants used!
Unsuitable lubricant may contaminate the medium. In oxygen
applications there is a risk of explosion.
▶
In specific applications, e.g. oxygen or analysis applications,
use appropriately authorized lubricants only.
WARNING!
Risk of injury from damaged devices!
An incorrect tool and an excessive tightening torque may
damage the device during installation.
▶
Use an open-end wrench to install the actuator, never a pipe
wrench.
▶
Observe tightening torque (40 ± 3 Nm)
→ Grease pipe thread before re-installing the actuator
(e.g. with Klüber paste UH1 96-402 from Klüber).
→
For control function A: Pressurize control air connection with
compressed air (5.5 bar) so that the pendulum disc is lifted off
the valve seat and is not damaged when screwed in.
→ Screw actuator into the valve housing.
Observe tightening torque (40 ± 3 Nm)!
6.3 Pneumatic connection
WARNING!
Risk of injury from unsuitable connection hoses!
Hoses which cannot withstand the pressure and temperature
range may result in hazardous situations.
▶
Use only hoses which are authorized for the indicated pres-
sure and temperature range.
▶
Observe the data sheet specifications from the hose
manufacturers.
6.3.1 Control air connections
The 45° angle connection, which can be ordered
separately, is recommended for the control air con -
nection! In this case the free-moving hose length
should be min. 250 mm. If the hose length is shorter,
the durability and function of the plug-in coupling
will be impaired! Order no. 903383
If a straight control air connection is used, the
free-moving hose length should be min. 400 mm.
If the hose length is shorter, the durability and
function of the plug-in coupling will be impaired!
Risk of crushing!
▶
Due to the risk of crushing, a 90° control air
connection must not be used!
