ACTUATORS - RP SERIES
Australian Pipeline Valve - Installation, Operation and Maintenance Manual
6
Rotation and stroke adjustment: -
The stroke for actuators is as follows:
Standard construction: 90° rotation with stroke adjustment at 0° and 90° (+ or - 4°)
Type 120° stroke: 120° rotation with stroke adjustment at 0° and 120° (+or-4°)
Type 180° stroke: 180° rotation with stroke adjustment at 0° and 180° (+or-4°)
Lubrication: -
The actuators are factory lubricated for the life of the actuator in normal working conditions.
The standard lubricant type GSTD is suitable for use from -40°C (-40°F) to +80°C (+176°F)
.
For extreme low temperature (LLT) and high temperature (HT) service, special grease is required: please
contact us.
Construction: -
Rack & pinion actuator design suitable for both indoor and outdoor installations.
Water Ingress Protected
O-Rings are fitted on body caps and all joints. This ensures an effective seal to prevent ingress of water.
ISO Valve Mounting
The RP Series Actuators interface meets ISO standard, and meets the dimensional requirements of ISO defined
for each torque range.
Standardised Interface
The shaft driven accessory interface conforms to NAMUR and are identical on all RP Series, allowing
standardisation of accessory mounting hardware and installation practices.
Protection and corrosion resistance: -
All the actuators are supplied with corrosion protection for normal environments. For corrosion resistance of
the different types of protection see technical data sheet. Before installing the actuator in aggressive
environment, ensure that the selected protection level is suitable.
For low and high temperature service, special grease and special components are
required. Please contact us. Working at high or low temperature can affect the life
and the output torque of the actuator.
The operating time depends on several factors such as supply pressure, supply
system capacity (pipe diameter, flow capacity of pneumatic accessories), valve type,
valve torque and figure, applied safety factor, cycle frequency, temperature, etc.
