Advantages

1 Hard Anodized BodyThe extruded aluminum body incorporates an advanced,hard anodizing treatment on the internal and externalsurfaces. This provides reduced friction, increaseddurability and corrosion protection. The body can alsobe provided in a number of optional finishes includingPTFE coated, electroless nickel plated and a variety ofpolyester powder coated colors.

2 Large Piston DesignThe EPR actuators are designed with an optimally sizedpiston rack. This minimizes backlash between the rackand pinion ensuring that they are precisely engaged. Thisfeature guarantees excellent power delivery and accuratevalve modulation.

3 Advanced Rack and Pinion Design A compact, rugged construction, with dual rack and pinion,guarantees stable torque output throughout the actuator’s travel. The design is also suitable for high-cycle, high-speed duties.

4 Travel AdjustmentThe EPR-Series actuators provide two external travel stops allowingfor ±5° adjustment in both open and closed positions. This allowsaccurate valve alignment and provides actuator travel adjustmentfrom 80° to 100°. Optional bolts fitted to the end caps can provideadditional travel adjustment, for the open position. The externallyadjusted bolts can provide open position travel from 0 to 100。.

5 Piston Guide PlateA permanently lubricated, replaceable guide plate is fitted to thepiston rack to remove lateral deflection and ensure smoothoperation by eliminating metal to metal contact, improving wearresistance and increasing efficiency.

6 Drive Shaft Bearings The EPR-Series actuators have self-lubricating, replaceable shaftbearings providing low-friction, and high wear resistance. Thisenables high cycle life and reliable performance.

7 Corrosion Protection Polyester powder coated end caps provide excellent anti-corrosionproperties, and optional finishes are available if required, includingPTFE coating, electroless nickel plating or hard anodizing.

Advantages

Torque Outputs

Double Acting The EPR-Series actuator isdesigned such that torqueis independent of actuatortravel and is constantthroughout the travel range.

Spring Return Spring return actuatorshave both spring and airtorques and each torquehas a higher start figurethan the end figure. TheEPR-Series actuator is designed such that the spring and air starttorques are equal, as are the spring and air end torques.

Operational Data

Media The operating media should be clean instrument air or non-corrosivegas. The media can be lubricated or non-lubricated. It should have adew point of -20¡� or at least 10¡� below the ambient temperature,and a maximum particle size of 50 micron.

Supply PressureThe EPR-Series is rated for continuous operation at pneumaticsupply pressures from 2.5 to 8 bar (36 to 116 psig).

Temperature Range Standard EPR actuators are designed for operating temperatures of-20°C to 80°C (-4°F to +176°F).Options are available for low -40°C (-40°F) and high +150°C (+302°F)temperatures, and special requirements can be supplied on request.

Torque OutputsThe EPR double acting torque output ranges from 12 to 4509 N.m(108 to 39946 ins.lbs.) and the spring return actuator producesspring end torques from 4 to 1252 N.m (38 to 10166 ins.lbs.).

Actuator Operation

Double Acting Configuration As standard the actuator is supplied for counterclockwise rotationwhen pressure is applied to port A. This pressurizes the internalchamber driving the pistons apart. When air is applied to port B theend chambers are pressurized driving the pistons together causingclockwise actuator rotation.If required, the pistons can be inverted in the housing resulting inclockwise rotation when pressure is applied to port A.

Spring Return ConfigurationAs standard the actuator is supplied for clockwise rotation in airfailure mode. When port A is vented the springs drive the pistonstogether, causing clockwise rotation. When pressure is applied to portA the internal chamber is pressurized driving the pistons apart andcompressing the springs, causing anti-clockwise actuator rotation.port B is used as a breather for the spring chamber swept volume.
