1. Introduction
This manual is intended to support users of tilting disc type check valves in installation, operation
and maintenance.
Danger!
If the following attention and warning notices are not followed, danger could
result
, and the manufacturer’s guarantee could become ineffective.
Please contact KROMBACH in case of any questions.
2. Intended use
Tilting disc type check valves are exclusively intended, after they are installed in a pipeline system
(between flanges or by welding) and after the motor (if ordered) is connected to the control system,
to let the medium flow through in flow-through direction, but to prevent the back flow.
Tilting disc type check valves are in principle self-acting valves. The oil brake damps either the
closing or the closing and opening (according to customer request). Additional actuator parts are
mounted for special functions (order related), for example automatic closing, automatic opening
etc.
⇒
Media that are to be allowed through must not contain more than a very small proportion of solid
matter.
⇒
The use of tilting disc type check valves with abrasive media is not recommended.
⇒
The maximum permissible pressure in conjunction with the maximum permissible temperature is
stated in the type plate of the armature.
⇒
Tilting disc type check valves should not be used for media which have a tendency to build up
internal deposits.
⇒
The installation of the check valves in turbulent streaming before or behind a pipe elbow is not
allowed.
⇒
Section 3.2 “Safety instructions for the operator” must be observed in using the armature.
3. Safety instructions
3.1.
General safety instructions
The same safety regulations apply for armatures as for the pipeline system in which they are
installed and as for the control system to which the motor is connected. The present manual only
provides such safety instructions as are to be followed
additionally
for armatures.
Additional safety instructions for the oil brake are contained in the manuals.
3.2. Safety
instructions for the operator
It is not within the responsibility of the manufacturer KROMBACH, and must therefore be ensured
when using the armature, that:
⇒
the armature is used only for the purpose for which it is intended, as described in Section 2
Danger
to life
Armatures whose pressure / temperature range (= “Rating”) is not sufficient for the
operating conditions must not be operated: the permitted value can be read from
the type plate of the armature. It is mandatory to obtain approval from KROMBACH
where the armature is to be used outside these ranges.
Failure to observe this requirement can lead to danger to life and limb and
cause damage in the pipeline system.
