SOLENOID VALVES 2 3/2 no voltage release (tamperproof) U Series manual reset construction 1 3 327 1/4 FEATURES • The valves are certified according to IEC 61508 Functional Safety data and have SIL-3 capability (TÜV & Exida certification) • Compact Tamperproof/Manual Reset function which means that the valve has to be energized as well as manually operated before it stays in the "latched" position. Because of the tamperproof feature there will be no flow from port 3 to port 2 if only the push button is pressed. The No Voltage Release (NVR) function will make sure that the valve trips when de-energized • The solenoid valves are recommended for pilot applications with basic flow, wide pressure ranges and no minimum operating pressure • PTFE rider rings and graphite-filled PTFE seals reduce friction and eliminate sticking • Coils used in metal enclosures have class H insulation materials • Peak voltage suppression diodes are standard in DC solenoids with metal enclosures • The solenoid val
