MAINTENANCE MANUAL
The solenoid valves have Buna-N O-Rings to seal inlet and outlet ports. The plugger return is
pneumatically performed by differential pressure, without springs.
G.T. Attuatori offers solenoid valves both with NAMUR standard mount, for direct mounting on actuators
from GTX.110 through GTX.255, and proprietary type mount for direct mounting on actuators from GTX.52 through
GTX.92.
Although G.T. Attuatori uses a proprietary mounting pattern for smaller actuators, G.T. Componenti also
offers a special adapter plate to allow for a NAMUR standard pattern solenoid valves to be mounted on any
actuator, as shown in figure 9.
G.T. Attuatori offers 4 standard models of solenoid valves:
Voltages: 24 - 48 - 110 - 220 V / AC. (50-60Hz.)
12 - 24 - 110 V / DC.
Consumption: 3.5 Watt (DC.) 5 VA (AC.)
Pressures: Min. = 2.5 Bar Max. = 10 Bar
1 - SV.1 Single Solenoid, ports 1/4" NPT Mounting on actuators with NAMUR adapter plate:
from GTX.45 through GTX.92
Direct mounting on actuators: from GTX.110 through GTX.300
KV Factor = 9
In addition to these 4 standard models of solenoid valves, with nylon fiberglass filled coils, G.T. Attuatori offers
also Epoxy Resin filled coils, for all standard voltages and also for other voltages, when request, always with same
consumption data.
