• Electrically powered, 115 or 230 V AC, single
phase, 60 Hz.
• Spring return, fail to safe position on loss of
main power supply
• Thermally protected motor
• Standard Beacon position indicator
• 2 SPDT switches for end of travel indication,
dry contacts

down time.
• Easily removable housing cover provides easy
access for yoke mechanism inspection.
• High strength alloy steel or 17-4PH stainless
steel output shaft transmits torque without
fatigue.
• Sintered bronze or PTFE composite output
shaft bearings eliminate side loading of valve
stem to maximize stem packing performance.
• Strong, corrosion-resistant chrome-plated
steel piston rod for enduring high-cycle
applications.
• Sintered bronze piston rod bushings provide
low-friction support and precise alignment to
increase efficiency, reduce maintenance and
extend actuator life.
• Heat-treated stainless steel thrust pin and
rollers transfer piston force to yoke to reduce
friction, for longer life and more efficient
torque transmission.
• PTFE guide bands ensure low-friction
piston guidance protecting cylinder walls
from potential scoring and extending seal
performance with a continuous cylinder
wiping action.

HPU (HYDRAULIC POWER UNIT) MODULE
Steel reservoir
for long life and rugged
operations
Manifolded hydraulic
controls
include relief valves,
solenoid valve, check valve
and speed controls.
Motor
with thermal
protection
The HP electro-hydraulic actuator is a self-contained unit consisting of a hydraulic power unit
with oil reservoir, electric control limit switches, terminal block, open/closed position beacon and
a hydraulic actuator.
The HPU module operates on single phase 115 V AC (or optional 230 V AC). Power is applied to the
actuator closing the solenoid valve included in the HPU manifold, and starting the HPU motor. The
actuator opens and the motor shuts off when a limit switch in the control box opens. The solenoid
valve remains energized.
The electric spring return actuator closes on loss of power to the unit either by remote control or
by power failure. Spring stroke speed of ≤ 5 seconds standard (adjustable to slower speeds).

STANDARD SCOTCH YOKE DESIGN
EXPERTS IN ACTUATOR DESIGN
We understand that the most efficient design
for one torque range is not the most efficient
for another, so the EHP fail-safe actuator uses
our proven standard actuator design.

BIFFI MORIN EHP SERIES ACTUATOR
SCOTCH YOKE DESIGN
DESIGNED WITH A RUGGED HEART
Scotch yoke design
The heart of any scotch yoke actuator is the yoke. The EHP actuator uses either 17-4PH or ductile
iron for this critical area as standard.
The yoke is the mechanism used to convert linear force to torque. The yoke is critical to actuator
performance. It must be rugged, yet precisely machined to give long life at high efficiency - all our
yoke designs meet this test.
Principles of construction
Using high quality materials of construction and modern rugged design concepts provides the
standard for high quality, low cost valve actuation. The actuator housings are all machined from
ductile iron castings. This produces a rugged, low cost product through reduced machining time
and by eliminating wasteful excess material. Housings are then epoxy electro-coated inside and
out for corrosion resistance. Any components that rotate or slide during operation, such as the
high strength output shaft, chrome-plated piston rod, stainless steel thrust pin or the ductile iron
piston, are all supported by replaceable friction reducing bearings.
Bi-directional travel stops
Adjustable stops on each end cap provide the flexibility of accurate valve rotation positioning at
the end of the “open” and “close” stroke. Both stops are located on the cylinder centerline, the
optimal position to maximize travel adjustment and eliminate any detrimental side loading on the
travel stops. Adjustable from 82° to 98°.
Spring designed for safety
All spring return models incorporate a “man safe” spring design that allows the actuator to be
safely assembled and disassembled in the field without the need for special tools. The integral tie
rods are bored and tapped to provide a means of loading and unloading the spring in a safe and
convenient manner.
