Refer to Engineering Section for details.
These solenoids are intended for use on clean, dry air or
inert gas filtered to 50 micrometers or better. To prevent
freezing, the dew point of the media should be at least
18°F (-8°C) below the minimum temperature to which any
portion of the clean air or gas system could be exposed.
Instrument air in compliance with ANSI/ISA Standard
S7.3-1975 (R1981) exceeds the above requirements and
Nominal Wattage is 0.35 @ 24 VDC is, therefore, an acceptable medium for these valves.
Maximum Allowable "Off" State Current to the Valves must be less than 1 mA.
Electronically Enhanced "IS" Solenoid:
Maximum Capacitor Charge Time — 1 second
Minimum Time between Cycles — 1 second
Minimum Drop Current to Reset Electronic Coil — 2 mA
Nominal Temperature Rise at 24 VDC and 300 Ohms — 2°C (36°F)
Maximum Recommended Wire Run (#18 Wire) — 1.5 miles from barrier to valve
Important: Minimum series resistance of 200 ohms required in wiring
circuit if a safety barrier is not used for non-"IS" system.
Maximum Entity Parameters
Standard Voltage: 24 VDC only (±10%)
Minimum Operating Current: 0.028 amps
