Installation

Installation

Valve and actuator are delivered ready 
mounted.
Refer to the corresponding mounting and 
operating instructions for more details on the 
actuator used.

3.1 

Mounting position

The valve can be mounted in any desired 
position.

 

Î

Observe the restrictions for the actuator 
used.

NOTICE

Install the valve free of stress and 
with the least amount of vibrations as 
possible. If necessary, support the 
pipelines near the connections. Do 
not attach supports directly to the 
valve or actuator.

Pipeline routing

To ensure that the control valve func-
tions properly, the pipeline must be 
straight and without any manifolds 
or disturbances for a distance of at 

least 6 times the valve size (DN) up

-

stream and downstream of the valve. 
Contact SAMSON if this distance 
cannot be observed.
Flush the pipeline thoroughly before 
installation of the valve.

3.2 

Arrangement of the valve

Install the valve as shown in Fig. 2 depend-
ing on whether it is to be used for mixing or 
diverting service.
The plug arrangement (i.e. either mixing or 
diverting valve) is indicated on a label at-
tached to the valve body.
Fail-safe action: the valve shuts off the flow 
of the heating medium or opens the flow of 
the cooling medium.

3.3 

Strainer and bypass

We recommend installing a SAMSON 
Type 2 N Strainer upstream of the valve, and 
upstream of both inlet ports in mixing valves.
We recommend installing a shut-off valve 
both upstream of the strainer and down-
stream of the valve to ensure that the plant 
does not need to be shut down for mainte-
nance. In addition, install a bypass line.
