Installation
GPS valves in sizes DN 100 to DN 150 are
always installed in vertical position fig. 2a.
GPS valves in other sizes are installed as
shown in fig. 2b, i.e. in 90° from vertical
position with pilot valve and side branch
downwards. If there is welding slag and/or
dirt in the system, it is strongly recommen-
ded to install strainers in connection with
the GPS valve.
It is important always to install strainers in
the pipes leading to the pilot valves.

Flow direction
IMPORTANT: The flow direction must be
from the side branch towards the cone
(fig. 2a+2b).
Welding
Remove the actuator before welding (fig.
3). OBS: Be sure not to damage the
teflon cone ring and the spindle. If
these parts are damaged the valve
will leak.
Assembling
Remove welding slag and dirt from pipes
and housing. The valve cone is protected
with a cap. (B) Remove this cap before
the valve is assembled (fig.3). OBS: Only
1 hot gas supply is required (Cf. Illustration
A on fig. 4a); connect this supply to the
pilot valve armature.
