Technical Data
Max. supply pressure : 10 bar g
Rated supply pressure : 8.3 bar g
Output torque @ 5.5 bar g
Double Acting models : up to 2054 Nm
Spring Return models : up to 1414 Nm
Temperature range : -30° to +90°C*
with standard
components.
* For higher temperature applications other
materials available on request
Double Acting (air to air) and Single Acting (spring
return), 90° operation, pneumatic actuators.
General Applications
For remote control of any quarter turn
application, for example Ball, Butterfly or
Rotary Plug Valves, Dampers etc.
Accessories
An extensive range of standard
accessories is available for direct mounting
to Keystone actuators.
- Solenoid Valves - weatherproof,
explosionproof or intrinsically safe.
- Limit Switchboxes - weatherproof,
explosionproof or intelligent.
- Positioners - pneumatic, electropneumatic
or intelligent.
- Declutchable manual override gearbox.
- High Visibility Indicator.
- Proximity sensing - weatherproof
intrinsically safe, or intelligent.
Features
? Compact rack and pinion design utilising
the whole piston area to develop output
torque.
? Pistons with integral rack drive reducing
the number of dynamic seals, minimising
air leakage.
? Double pistons nullify sideloads on the
pinion shaft, minimising bearing wear.
? Springs epoxy painted and colour coded
for additional corrosion protection and
ease of identification.
? Hard anodised aluminium body, with
external ESPC finish, protects against
corrosive environments including
saliferous atmospheres.
? Alternative finish: electroless nickel plating.
? Female output drive enabling direct
mounting in certain applications, thereby
eliminating special connections and
guaranteeing correct alignment.
? Bottom entry pinion shaft.
? Anti-friction piston pads ensuring no
metal to metal contact, providing a
smooth operation. Ideal for modulating
or on/off control applications.
? Adjustable travel stops in both directions on
certain models (see pages 2 and 3).
? Grease lubricated for life.
