INSTALLATION AND MAINTENANCE
GP RANGE
3.0 Maintenance
3.1 Rotork actuators are designed to work for long periods of time in the most severe conditions. However, a preventative
approach to maintenance helps prevent costly down time and can actually reduce the cost of ownership. Rotork can provide
an actuator maintenance contract tailored to meet each customer’s individual requirements.
3.2 Any personnel working with or on the equipment must be properly trained for the work they are performing and be aware of
their responsibilities relating to health and safety in the workplace.
3.3 No inspection or repair should be undertaken unless it conforms to any applicable hazardous area certification requirements.
Under no circumstances should any modification or alteration be carried out on the unit as this could invalidate the
certification.
3.4 Before performing maintenance, the actuator should be isolated from remote control signals and the pneumatic/hydraulic
power supply. The system should be then be relieved of any internal pressure prior to disassembly.
3.5 Improper operation, adjustment or maintenance of the actuator and controls may, depending on the application, release
potentially explosive gas and or dangerous liquids.
3.6 After maintenance has been performed and re-assembly completed, follow the inspection guidelines as outlined section 3.6.
3.7 Periodic Inspection
3.7.1 Ensure that the actuator correctly operates the valve within the required cycle time. The actuator should be cycled several
times with all the existing controls e.g., remote control, local control and manual override; particularly if the actuator is not
frequently operated.
3.6.2 Verify that the power gas supply pressure value is within the required range.
3.7.3 Visually inspect external components of the actuator for physical damage.
3.7.4 Check pneumatic/hydraulic connections for leakage. Tighten pipe fittings as required.
3.7.5 Remove dust and dirt build-up from all actuator surfaces. They can inhibit cooling thus raising the temperature of the
actuator above the maximum allowable limit.
3.7.6 Inspect actuator paint work for damaged to ensure continued corrosion protection. Touch-up as required to applicable paint
specification.
