� 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 cannot be exhausted to 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. Minimum 15 psi Operating Pressure Differential when selection gasket

is in the internal position.� Can be used for dry natural gas service with the EF or EV prefix.� Normally closed = 130 psi. Normally open = 105 psi.

Nominal Ambient Temp. Ranges ImportantThese solenoids are intended for use on clean, dryair or inert gas filtered to 50 microns or better. To pre-vent freezing, the dew point of the media should be atleast 18˚F (-8˚C) below the minimum temperature towhich any portion of the clean air or gas system couldbe exposed. Instrument air in compliance withANSI/ISA Standard S7.3-1975 (R1981) exceeds theabove requirements and is, therefore, an acceptablemedium for these valves.
