FEATURES
• The valves are certified according to IEC 61508 Functional Safety data and have
SIL-3 capability (TÜV & Exida certification)
• The solenoid valves are recommended for pilot applications with high flow, wide
pressure ranges and no minimum operating pressure
• Coils used in metal enclosures have class H insulation materials
•
The core movement is guided to ensure optimal alignment. The special low friction
seal accomplishes a balanced construction at the specified temperature and
pressure range at minimum power levels
• Special rider rings eliminate sticking and provide exceptional service life
• No minimum operating pressure required
• Pressure can be applied at any port
• 316L stainless steel construction for highly corrosive atmospheres
• The solenoid valves satisfy all relevant EU directives
• Manual Operators are optional including an under pressure removable type
• Environmental NACE compliant and certified vibration resistant in combination
with WSCR solenoids

PRODUCT SELECTION GUIDE
STEP 1
Select the fluid temperature range and
seal material from the general table
on page 1. Select, based on the se-
lected seal material (if applicable), the
basic catalogue number. Also select
the pipe thread identification letter.
Example: G327A607
STEP 2
Select prefix (combination): Select
the appropiate operator from the
prefix table on the left. Select for this
operator in the electrical characteristics table on page 3: the power level
(LP,RP,MP,BP) the type of electrical
enclosure protection and the desired
temperature class.
Warning: the ambient temperature
range of your application may not
exceed the temperature range of
your operator (see also on page 3
the section: Explanation of temperature ranges of solenoid valves).

EXPLANATION OF TEMPERATURE RANGES OF SOLENOID VALVES
Valve 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)
Operator ambient temperature range The operator ambient temperature range is determined by the selected power level and the
safety code
Total temperature range The temperature range of the complete solenoid valve is determined by the limitations of both
temperature ranges above
