Application of European Directives
Fluids
The equipment is designed for the following fluids
(in accordance with the EU Pressure Equipment
Directive or Pressure Equipment (Safety)
Regulations in the UK):
 Fluids of group 2
Due consideration must be given to chemical and
corrosive influences.
Use in potentially explosive atmospheres
The equipment does not have its own potential
source of ignition (as per ATEX Directive). Please
pay attention to the following information:
When installed, static electricity may arise between
the equipment and the connected system.
When used in potentially explosive atmospheres,
the plant manufacturer or plant operator is
responsible for discharging or preventing possible
static charge.
If it is possible for medium to escape, e.g. through
actuating mechanisms or leaks in threaded joints,
the plant manufacturer or plant operator must take
this into consideration when dividing the area into
zones.
Task and function
Purpose
BK 15 equipment is used to discharge condensate
from steam in pipes and for venting steam lines.
The equipment features integrated non-return valve
action.
Function of the Thermovit controller
The equipment is fitted with a Thermovit regulator
that regulates the flow of the fluid. The Thermovit
regulator is screwed into the body.
The Thermovit regulator consists of a stack of
several bimetallic plates. As the fluid temperature
rises the plates deflect, thereby moving the stage
nozzle. The orifice is being closed.
When the installation is cold the Thermovit regulator
is open.
You can change the Thermovit regulator settings so
that the trap opens or closes at higher or lower
temperatures.
In the event of backflow, the pressure of the fluid
forces the nozzle stem into the nozzle support. As a
result the orifice is being closed.
