El-O-Matic develops and manufactures actuators for the automation of industrial valves. Our
product range includes pneumatic actuators, electric actuators and a wide range of control
accessories, such as switch boxes for position indication, solenoid valves for control signalling and positioners for modulating control.
Pneumatic actuators are required to operate
in a wide variety of applications; they have to
function first time every time, often under
very difficult circumstances. One actuator
may perform hundreds of cycles 24 hours a
day, whereas another may open and close just
once a month - then may stay open for
months on end, but still be ready to shut
down instantly on a failure signal.
The extremes of temperature, harsh duty and
corrosive atmospheres where actuators are
often applied demand the highest attention
to the quality of design and manufacture.
Products & Services
Valve actuators mount on valves and, in response to a signal, move a valve to a desired position using an outside power source.
Electric actuators mount on valves which, in response to a signal, automatically move to a desired position using an outside power source. Single-phase or three-phase AC or DC motors drive a combination of gears to generate the desired torque level.
Pneumatic valve actuators adjust valve position by converting air pressure into linear or rotary motion.
Fluid power controls and systems use pressurized, moving fluids within an enclosed circuit to generate, transmit, and control power.
Manual valve actuators do not require an outside power source. They use a handwheel or lever to drive a series of gears whose ratio results in a higher output torque compared to the input (manual) torque.
