Important

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 is, therefore, an acceptable medium for these valves.

Electrical

Nominal Wattage is 0.35 @ 24 VDC Maximum Allowable "Off" State Current to the valves must be less than 1 mA. Electronically Enhanced 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.

There are two exhaust flows in the exhaust mode (pilot and main). The pilot exhaust must be connected to the main exhaust when the air or inert gas can not be exhausted to the atmosphere. For "Quick Exhaust" valves, pressure port is 1/16", exhaust port is 1/4". IMPORTANT: A minimum operating pressure differential must be maintained between the pressure and exhaust ports. Supply and exhaust piping must be full area, unrestricted. ASCO flow controls and other similar components must be installed in the cylinder lines only.

Diaphragm and main disc FKM only (pilot is low-temperature NBR). Zero minimum when valve selection gasket is in external position and proper auxiliary air pressure is applied. See chart on page 136 for auxiliary pressure vs. mainline pressure. Minimum 15 psi Operating Pressure Differential when selection gasket is in the internal position.
