7 Functional description
Valves from this series are usually used as actuators within the meaning
of DIN IEC 60050-351.
The valve serves to reduce the pressure and quantity of a flow of me-
dium through the plug.
The flow of medium through the seat (20) is regulated by the position of
the plug (26). The plug (26) is adjusted with the aid of an attached actu-
ator, which acts on the Stem (50) connected to the plug (26).

8 Fitting
Place of installation The valve should be easily accessible from at least one side.
Include a catwalk or similar in the planning in case of greater heights.
An electric crane or block and tackle should be provided, depending on
the weight.
Valve with flanges After removal of the protective caps from the inlet and outlet sealing sur-
faces, valves with flanges are installed in the pipeline using gaskets and
bolts provided by the customer. Following the installation, check the
flange connection and the surface coating, in particular the area around
the contact surfaces of the flange joints. Damage to the coating caused
by transport or installation in the pipeline is to be treated with a suitable
coating system in order to restore the factory corrosion protection.
Valve with welded ends Valves with welded ends are welded into the pipeline. Following the in-
stallation, check the welded connection and the surface coating. Dam-
age to the coating caused by transport or installation in the pipeline is to
be treated with a suitable coating system in order to restore the factory
corrosion protection.
Please note:
CAUTION
Mounting position
► Pipeline horizontal
► Actuator above the valve
► Pay attention to the flow direction arrows on the housing connections
In case of a different mounting position, special measures need to
be taken to support the weight of the actuator!
Forces from the pipeline must not be transmitted to the valve.
A straight section of pipeline with a length of at least 10x the nominal
size of the pipeline must be provided for in front of and behind the valve.
Built-in parts and branches are not permitted.
A bypass line is recommended with shut-off valves before and after the
valve.
It recommended to install a dirt trap / filter before the valve.
NOTICE!Following the installation of the valve, check that the installa-
tion conditions mentioned have been met.
Attachment of an actuator The valve enables the attachment of different actuators. Various mount-
ing kits and couplings are available for this.
The actuator must be mounted according to the actuator manufacturer's
operating manual.

ARCA Regler GmbH 9 Commissioning / Decommissioning
Series 8C D / 6H D 19 / 2811.2018 / 1.0
9 Commissioning / Decommissioning
Before the initial
commissioning In order to avoid damage to the trim due to possible existing contamina-
tion in the piping network, the piping network must be cleaned by rinsing
and if necessary pickling.
The following procedures are recommended:
Rinsing with rinsing set A rinsing set and rinsing flange(s) is mounted in place of the trim.
▪ Completely dismantle the valve so that only the housing remains in
the pipeline
▪ Mount the rinsing set in place of the seat (to be ordered separately)
▪ Mount the rinsing flange(s) (to be ordered separately)
▪ Rinse and if necessary pickle
▪ Dismount the rinsing set and the rinsing flange(s)
▪ Clean the valve and replace the seal(s)
▪ Mount the trim and completely reassemble the valve
Rinsing with spacer A spacer is installed in the pipeline in place of the valve
▪ Remove the valve from the pipeline (flange-mounted valves only)
▪ Install the spacer in the pipeline
▪ Rinse and if necessary pickle
▪ Remove the spacer from the pipeline again
▪ Replace the seals
▪ Install the valve in the pipeline again
Commissioning ▪ Pay attention to the chapter entitled [2] Safety
▪ Avoid thermal shocks
– Bring the valve slowly up to operating temperature
At a temperature difference of 300 K or more, the speed of tem-
perature change must be restricted to max. 2 K/min.
▪ Check the flange connections for leaks
– Tighten the bolted connections diagonally. Refer to the chapter
entitled [12] Torque tables for the tightening torques
▪ Check the stem sealing for leaks
– See the chapter entitled Stem seal – Detail X for this
Decommissioning We recommend the following procedure for taking the valve out of ser-
vice:
The valve remains installed In case of lengthy standstills, the valve and the pipeline must be emptied
and rinsed, depending on the operating medium.
The valve is removed ▪ Pay attention to the chapter entitled [2] Safety
▪ Remove the valve from the pipeline
▪ Treat the interior of the housing with a suitable preservative and seal
the openings with suitable caps

9 Commissioning / Decommissioning ARCA Regler GmbH
20 / 28 Series 8C D / 6H D11.2018 / 1.0
▪ To protect against corrosion, treat all unpainted parts and surfaces
made of materials that are not rustproof with a suitable preservative
Recommissioning NOTICE!All seals must be replaced if the valve has been out of service
for more than one year.
▪ Mount the valve in accordance with the chapter entitled Fitting
▪ Carry out the work according to the chapter entitled [10.1] Care
▪ Commission the valve according to the chapter entitled [9] Commis-
sioning
