Operation
NOTICE
!
Risk of valve damage due to a sudden
pressure increase and resulting high flow
velocities.
Slowly open the shut-off valve in the pipeline
during start-up.
Pressure testing the plant
All plant components must be designed for
the test pressure. If necessary, remove the
regulator (use an adapter) from the pipeline
or remove the control line (11) of the pres-
sure actuator at the valve and seal the open
connection with a blanking plug (see Ta-
ble 4).
NOTICE
!
Risk of damage to the diaphragm actuator
due to impermissible excess pressure.
The test pressure must not exceed the nomi-
nal pressure at the actuator by 1.5 times on
testing the pressure of the plant when the
regulator is already installed.
Rinsing the plant
1. After filling the plant, first completely
open the consumer
2. Adjust the maximum flow rate at the reg-
ulator (see section 6.1).
3. Rinse out the pipeline at full flow rate for
several minutes.
4. Check the strainer (e.g. measure the
pressure drop) and clean it, if necessary.

6.1 Adjusting the set points
NOTICE
!
− The TROVIS 57xx and Type 58xx Electric
Actuators are configured as described in
the actuator documentation (Referenced
documentation on page 8).
− The Type 2430 Control Thermostat is
adjusted as described in the associated
documentation (Referenced documentation
on page 8).
The flow rate can be adjusted either when
the electric actuator is mounted on the valve
or without a mounted electric actuator.
Î Completely open the control and shut-off
valves or the bypass valve in the plant.
To adjust or change the flow rate set point,
proceed as follows:
Always adjust the set point based on a
closed restriction.
