ACTUATOR CLOSE-OFF PRESSURE RATING (kPa)
a b
a
Close-off rated for ANSI IV (.01%) with pressure at inlet (port A). Ratings for normally open valves are with indicated supply air pressure applied to actuator. Ratings for normally
closed valves are within 7 kpa or less applied to actuator. See “Valve General Information” section for seat leakage ratings.
b
Close-off pressure ratings describe only the differential pressure which the actuator can close-off with adequate seating force. Consult valve body specifications for other limitations.
