ENGLISH
DELIVERY
The GPS valve is delivered in 2 separate
parts (fig. 1):
-
Valve with actuator and solonoid valve
(NC) 10 Watt
-
Coil for Pilot valve (NC) 10 Watt
REFRIGERANTS:
R717 (ammonia)), R22, R134a, R404A,
R407, R407B, R407C, R744, R600, R600a
and R290.
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
recommended to install strainers in con-
nection with the GPS valve. It is impor-
tant 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. Remove this cap before the
valve is assembled (fig.3). OBS: Only 1
hot gas supply is required (Cf. Illustra-
tion A on fig. 4a); connect this supply
to the pilot valve armature.
TIGHTENING
Use a torque wrench to tighten the 8 bolts
connecting the housing with the actuator.
Tighten the bolts in accordance with the
table fig. 4b.
MANUAL OPENING
For instance by failure of current, see
instruction overleaf.
COLOURS
In factory the valve housings are painted in
a oxide yellow primer. The actuator is
metallized.
