FEATURES
• The redundant solenoid valves are recommended for fail safe pilot applications
combining high flow, wide pressure range and absence of minimum operating
pressure
• When the redundant valve controls an actuator, the actuator remains in position
as long as one of the two solenoid valves (coils) is energized. To exhaust the
actuator both solenoids have to be de-energized
• PTFE rider rings and graphite-filled PTFE seals reduce friction and eliminate
sticking
• Coils used in metal enclosures have class H insulation materials
• Dedicated execution for low power
• Dedicated execution for extreme low ambient temperatures
• Peak voltage suppression diodes are standard in DC solenoids with metal
enclosures
• The solenoid valves satisfy all relevant EC Directives
• Environmental NACE compliant and certified vibration resistant in combination
with WSCR solenoids

EXPLANATION OF TEMPERATURE RANGES OF SOLENOID VALVES
Valve temperature range
Operator ambient temperature range
Total temperature range
The valve temperature range (TS) is determined by the selected seal material, the temperature
range for proper operation of the valve and sometimes by the fluid (e.g. steam)
The operator ambient temperature range is determined by the selected power level and the
safety code
The temperature range of the complete solenoid valve is determined by the limitations of both
temperature ranges above
