www.Fisher.com Fisher ™ 1068 Rotary Vane Actuator Fisher 1068 rotary vane spring return and double acting pneumatic actuators have a large range of sizes that can be mounted to rotary shaft valves. The 1068 rotary vane actuator is one of the simplest and most reliable units for quarter-turn rotary actuation. The 1068 design offers a wide torque range. The double acting actuator is capable of outputting the same torque at every valve rotation. The spring return actuator has torque outputs that are linear, and balanced for both air-to-open and air-to-close applications. Features n Accuracy -- The 1068 actuator vane and shaft are an integral casting, removing a means of lost motion or dead band. Clamped coupler used on size 5i through 15i spring return minimizes the possibility of lost motion between the actuator and valve shaft connection. n Integral Air Passage -- The 1068 sizes 5i through 15i spring return actuator incorporates an integral air passage that eliminates the need for external tubing and fittings when paired with a Fisher FIELDVUE™ DVC6200 digital valve controllers. The double acting unit will require minimal external tubing. n Compact Construction -- Reduced valve/actuator envelope dimensions leads to more mounting flexibility when space is at a premium. n Long Life Service -- Tested to over 1 million cycles. Rugged construction provides stability, corrosion resistance, and protection from demanding process control applications. 1068 DOUBLE ACTING ACTUATOR X1590 1068 SPRING RETURN ACTUATOR X1591 n Improved Ease of Use -- Integral mounting pad for DVC6200 eliminates the traditional mounting bracket and reduces the number of parts required to mount for the size 5i through 15i spring return and double acting actuators. 1068 Actuator D104404X012 Product Bulletin 61.2:1068 July 2019

Fisher™ 1068 Rotary Vane ActuatorFisher 1068 rotary vane spring return and doubleacting pneumatic actuators have a large range of sizesthat can be mounted to rotary shaft valves. The 1068rotary vane actuator is one of the simplest and mostreliable units for quarter-turn rotary actuation.
The 1068 design offers a wide torque range. Thedouble acting actuator is capable of outputting thesame torque at every valve rotation. The spring returnactuator has torque outputs that are linear, andbalanced for both air-to-open and air-to-closeapplications.
Features� Accuracy -- The 1068 actuator vane and shaft are an
integral casting, removing a means of lost motionor dead band. Clamped coupler used on size 5ithrough 15i spring return minimizes the possibilityof lost motion between the actuator and valve shaftconnection.
� Integral Air Passage -- The 1068 sizes 5i through 15ispring return actuator incorporates an integral airpassage that eliminates the need for external tubingand fittings when paired with a Fisher FIELDVUE™DVC6200 digital valve controllers. The doubleacting unit will require minimal external tubing.
� Compact Construction -- Reduced valve/actuatorenvelope dimensions leads to more mountingflexibility when space is at a premium.
� Long Life Service -- Tested to over 1 million cycles.Rugged construction provides stability, corrosionresistance, and protection from demanding processcontrol applications.

1. The torque output of the spring return actuator is optimized for an 80 psig operating pressure. The actuators are still capable of creating usable torque at 60 or 70 psig, but the net torqueoutput will be significantly reduced and will no longer be balanced with the spring torque. See table 5 for spring return torque valves at 60 or 70 psig.
Features (cont.)� Large Size Range -- The 1068 actuator offers sizes
that cover torques up to 150,000 in•lb.
� Single Moving Part -- The rotary vane actuatorensures a long service life with minimalmaintenance.
� Corrosion Resistant -- Robust epoxy coatedzinc/titanium alloy, or aluminum housings, epoxyenamel coated inside/out to provide substantialcorrosion resistance.
� Efficiency -- The small internal volume minimizesthe air consumption of the 1068.
Options/Available Configurations� Double Acting -- Air supplied to both sides of the
vane which is the only moving part. Allowing for thehighest torque values and compact design.
� Spring Return -- Designed for long cycle life andhave a balanced net and spring stroke torque.
Fisher 1068 size 5i through 15i spring return actuatorsfeature an integral air passage that eliminates the needfor tubing and fittings with the DVC6200. The 1068actuator with the DVC6200 digital valve controller is acombination for precision and repeatability in the field.
