EL-O-Matic Pneumatic actuators are powerful
and compact double rack and pinion units for use with
ball, butterfly and plug valves and any device requiring
accurate and dependable quarter turn rotary motion.
The use of high grade steel and aluminium components together
with EL-O-Matic's patended 3 point piston support provides
a tough reliable unit for the automation of today's high
performance industrial valves. Modern synthetic bearings
ensure no metallic contact between moving components. |
|
Spring return actuators incorporate the multiple spring concept
for maximum flexibility, they are also "field reverseable".
Safety features include an anti-blow out spindle and a spring
retaining system which ensures no spring tension on disassembly.
A wide range of control options are available to cover each
and every industrial application.
'E' Series actuators incorporate a body of cast aluminium
and have pistons where the rack teeth are precision machined
onto the aluminium casting. Spring return versions have a
maximum of 6 springs, 3 in each end cap assembled as a concentric
stack.
'P' Series actuators cover the large end of the torque
range. These all incorporate a body of cast aluminium and
have steel for the rack on pinion drive. Spring return versions
have a maximum of 14 springs 7 in each end cap assembled within
a hexagon pattern.
All actuators have mounting flanges and drives to ISO 5211.
Mounting kits can be provided for most of the worlds quarter
turn valves.
