2 Designed to fit NAMUR shaft FEATUREST orque output range from 40 to 32,315 inch-pounds depending on air supply pressure and/or spring pressure rating of 120 PSI. Standard temperature range is -4oF to 185oF with Buna seals (-40oF to 350oF available with Viton ).TRAVEL STOPSDual travel stops located on the Actuator body provide +/- 5o of travel adjustment for models 52 to 125. Stops are not located in the pressure containing body of the actua-tor, reducing the number of possible leak paths and necessary GUIDESL arge self lubricating PTFE piston thrust blocks and anti-friction rings are designed to reduce internal Actuator friction and maintain piston thruststability.
3 Lower friction means more torque output vs. supply MOUNTINGThe FNW Actuator is designed for direct mounting to many FNW valves using ISO 5211 bolt patterns and 8-point female MOUNTINGThe Actuator s accessory mounting pad meets international NAMUR and ISOstandards that match accessories such as limit switches, positioners, and position monitors with NAMUR shafts. This makes mounting of accessories economical and MOUNTINGThe FNW Actuator is designed with aninternational NAMUR solenoid bolt pattern that allows for direct mounting of NAMUR style solenoids. This configurationeliminates the need for costly pipe nipples, tubing, and mounting brackets.
4 * Note: FNW actuators are stocked with full spring sets (models 52 to 140 have spring set 5, models 160 to 200 have spring set 6, and model 270 has spring set 8). Spring sets are reconfigurable. See torque sheets for Spring Set Configurations* model 52 to 140 model 160 and 200 model 270 ExternalExternalInternalInternalCentralP retensionedSpringsStandard CCW Rotation The standard action of the FNW Valve Actuator is CCW to open and CW to close for typical valves. This action is field reversible for CW to open and CCW to close (typically for fail open spring-return applications).
5 Reversed CW Rotation Double-ActingFor counterclockwise output rotation (typically Valve opening), apply supply pressure to port A, driving the pistons apart,exhausting air from port B. Supply pressure to port B, port Aexhausting, will drive the pistons in for clockwise counterclockwise output rotation (typically Valve opening), apply supply pressure to port A, driving the pistons apart,compressing the springs, exhausting air from port B. Springforce rotates the Actuator clockwise when supply pressure to port A is rack and Pinion Actuator designs usually rely exclusively upon c-ringsor spiral retainers to hold the Pinion in place.
6 If these devices weaken or break off, the Pinion can blow out the bottom of the grooved Pinion and rack design creates an added mechanical hold to keep the Pinion from blowing out the bottom of the Actuator . In addition, the groove keeps the piston on track during the stroke and helps eliminate side Housing Nickel plated extrudedaluminum(also in hard anodized aluminum) Anti-Blowout Pinion steel (nickel plated) Lower Pinion O-ring - NBR 70 Upper Pinion O-ring NBR70 Pinion Spacer Bearing PTFE (15% Graphite) Cam Spacer Ring PTFE (15% Graphite)
