Keystone EPI 2 Electric Actuator
The Keystone EPI2 series is the most innovative all-in-one actuator solution for the automation of quarter-turn valves and dampers. With a huge number of standard features included in a small, compact design, this new series of electric actuators greatly simplifies valve, actuator and control system integration.Available with both weatherproof and explosion proof environmental ratings allows for a wide range of applications in most plant environments. The unique epicyclical gear train eliminates the need for mechanical/electrical brakes and hand wheel clutch mechanisms.The EPI2 direct mounts to most Tyco valves, eliminating the need for expensive mounting brackets.

Electric motor and universal power
supply
Innovative POWER SUPPLY MODULE™ to
accept 100 V to 240 V DC and AC 1-phase
input voltages at 50 and 60 Hz provides
flexibility for a broad range of applications.
Over temperature device to protect the motor
and electronics is included.
Local indicator
Standard “Window” type located in the cover.
Travel stops
Mechanical stops on the base of the actuator
provide +/- 10 degree over/under travel in
each direction (70 degree minimum to 110
degree maximum angular stroke).
Anti-condensation heater
Standard with 10 Watt thermostat will
activate the heater when the internal
temperature drops below +59°F.
Terminal enclosure
Terminal board is in a separate compartment.
Removal of the actuator’s control cover to do
field wiring is no longer required.
Four 1" NPT conduit openings allow flexibility
in wiring access.
Electronic controls
“Push-to-Run” 3 wire (Open/Close/Common)
remote control signals.
Torque sensing in both directions of travel,
adjustable in 10 steps from 40% to 100% of
the actuator’s rated torque output.
Absolute encoder is used for position
feedback.
Output speed independently adjustable for
the opening and closing directions.
Four SPST (NO/NC) latching contacts are
provided for fully Open/fully Closed remote
indication. Contact ratings are 5 Amp at
120VAC and 5 Amp at 30 VDC.
Base unit default settings
The actuators are provided with the following
default values:
• Closing limit by Position.
• Opening limit by Position.
• Stroking time for closing and opening;
18 seconds for models E006, E013, E025,
and E051, 30 seconds for the E091, and
66 seconds for the E171.
• Torque Limiting for closing and opening
set at 100% of nominal torque.
AWWA
Unit is tested to, and compliant with AWWA
C540.
