TITAN SEMI ROTARY ACTUATORS

DESIGN

Titan semi rotary actuators are designed for long life , suitable for heavy dutyapplications and available in a wide range of torque outputs.

The range comprises both single and double rack versions, the racks beinghydraulic driven against a pinion to provide a rotary output.

PERFORMANCE

Titan actuators are designed for maximum mechanical efficiency, the quoted torquefigures are 100% and take into account losses within the actuator.

The actuators will provide a constant torque output regardless of angular position,torque can be adjusted by regulating the hydraulic system pressure, speed ofoperation can be controlled by regulating the system flow rate.

POSITIONING

Titan actuators are available with standard rotations of 90°, 180°, 270° and 360°,standard variable end stops allow fine setting of each end of rotation position.

Standard position controls will allow a total of 20° angular adjustment i.e. 10° perend.

Mid rotation point is at 12 o’clock and is indicated by the position of the key wayor identified by an arrow on non keyed shafts.

CUSHIONING

Cushioning is used to decelerate rotation at the end of stroke and is effective overthe last 10 to 15 degrees of rotation ,use of end stops will reduce the availablecushioning length proportionally.

OUTPUT SHAFTS

Output shafts can be single or double sided, and can be supplied as plain keyed orsplined, all models can be supplied with keyed hollow shafts. For heavy dutyapplications, actuators can be supplied with a double shaft key.

MATERIALS

Titan actuators are manufactured in alloy steel for industrial applications,marinised and stainless steel versions are available for the offshore, food andsubsea industries.

SEALS

Actuators are fitted with nitrile seals as standard for use with mineral oil up to80°C.

Alternative seals can be supplied for higher temperatures, or to suit other types ofhydraulic fluid.

PORT POSITIONS

As standard, port positions are shown as on the data sheet, if required they can bepositioned at 90° or 180° to standard.

DOUBLE RACK VERSIONS

All TITAN actuators are available in a double rack configuration to provide twicethe torque output shown for single rack models. This configuration ensures that thepinion bearings are balanced by the racks during operation.

VALVE ACTUATORS

These variants can be supplied as spring returned or spring centred with visual orelectrical valve position indicators and manual overrides.

PAINT FINISHES

Actuators are supplied finished in enamel paint, they can be supplied in primeronly or to marine specification as required.

POSITIONAL CONTROL

Positional control can be supplied by end of stroke limit switches, proximityswitches or rotary potentiometer for full range resolution.

SPECIAL UNITS

All actuators can be modified for special requirements, units are available todirectly interchange with existing equipment and custom designed models can besupplied if required.
