Profile Home


ProMation Engineering Inc. manufacturers of an extensive array of
reliable industrial electric actuators where critical flow control is needed to ensure process uptime.

ProMation's products are used in a variety of applications including water and water treatment facilities, air control and isolation, high demand cooling, power generation, agriculture, metals processing, mining, chemical processing and oil and gas delivery and refining. ProMation's products utilize electrical and mechanical components specifically engineered for industrial environments. The engineering teams have designed specific products for OEM applications now in use worldwide.

ProMation quarter turn products are used on butterfly valves, ball valves and plug valves for fluids and are in use with dampers to control air flow. The failsafe mechanical spring return quarter turn actuators are used in air isolation dampers such as those found in tunnels, medical facilities or consulates. The ProMation Engineering linear actuators are used in rising stem and two or three port control valves, especially in larger high pressure applications where the expense and complication of dual seat valves are to be avoided.


ProMation's product line includes:

Quarter-turn non-spring
return electric actuators to
40,000 in lbs (4500 Nm)
of torque

Quarter-turn spring return
electric failsafe actuators to
2300 in lbs (260 Nm)
 of torque

Linear electric actuators to
4400 lbs (2000 kg) of force




Different Control Options packed with Features

ProMation offers on/off/jog as well as proportional control. The ProMation Premium Proportional Control board can accept multiple control signal inputs (4-20mA, 1-5VDC, 2-10VDC or
0-10VDC) as well as AutoCalibration for rapid setup. An alphanumeric display and joystick control provide the interface of the micro-controller. There are 5 diagnostic fault indicators and 14 data logging output values that are used for set up as well as efficient troubleshooting.


Electronic Options Engineered for Industrial Applications.

ProMation has engineered its electrical componentry to operate reliably in harsh industrial environments. RuggedBoard Design uses printed circuit boards to eliminate much of the wiring and connections that can cause premature failures. The Power Backup Units (PBU’s) provide electrical power for critical fail-safe positioning. Our Motor Control Centers (MCC’s) feature phase monitoring to ensure correct motor direction in 3 phase applications.


Feature Benefit
RuggedBoard Electrical Design Wiring connections are on printed circuit boards, increasing connection reliability as compared to typical connections found in other actuators.
Patented self-locking drive No motor brake required that can fail and require repair.
Clutchless manual override Easy manual adjustment -- even under load, without levers to push or pull.
Anti-condensation Heater and Auxiliary switches standard No additional cost to protect electronics from condensation. Common use of auxiliary switch is to identify when Open or Closed positions are reached.
Planetary or worm drive transmission gearing Tough, dependable torque transmission in a compact, quiet package.
Industrial grade metal internal components Epicyclic gears are carbon steel, internal hardware is stainless or painted steel, aluminum end of travel cams, and  Class F motors (275 deg F / 135 deg C) allow for longer service life.
NEMA 4/4X cast aluminum alloy housing Specified for outdoor use, corrosive or uncontrolled environments.
ISO5211 mounting system Increase range of valves that can be mounted without additional brackets. Simple inserts fit into oversized double square female coupling that can accept a wide range of valve stem configurations.
Easy-to-see raised position indicator Allows for quick visual verification of the true position of the actuated device.
Positive mechanical stops in base
(800"lb and above)
Overtravel protection for the actuated device during manual override operations.
Ambient operating range is
22F to +150F (-30C to +65C)
with internal heater
Allows for applications ranging from mechanical rooms to outdoor environments.
