- Page 8 ACTUATORS - RP SERIES 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.

ACTUATORS - RP SERIES 3 . 0 S T O R A G E & H A N D L I N G To ensure the seals remain flexible, and the actuator itself free moving during times of storage or intermediate services, air or nitrogen pressure should be cycled through the actuator at a minimum of three (3) times a month. -

ACTUATORS - RP SERIES b. Different pneumatic actuators have different air inlet sizes from 3/8” to 2” NPT. Using a smaller size Table 1 - Air Inlet sizes piping (or reduce orifice valves, solenoids, etc.) will reduce opening speeds. c. To ensure quick operation of the actuator, do not use a smaller tube or fitting size than the inlet size provided. - Page 11 4.4.1 General Sizing Rules for Soft Seated Ball Valves Valve and actuator torque values published are theoretical, however where required APV will perform a torque test prior to despatch. The real valve torque value can be higher depending upon the following listed factors as these factors can drastically increase (or decrease) the torque of soft seated ball valves.

For operating temperatures less then 0°C and above 140°C consult Australian Pipeline Valve. Temperature Multiplier = T emp °C ÷... - Page 14 ACTUATORS - RP SERIES Solenoid valve mounting Assembly of accessories: solenoid valves and switchboxes Before mounting a solenoid valve, ensure that the actuator is in it’s normal position (closed position) with pistons inwards. For standard rotation type “ST” (clockwise to close) assembly: the groove on the drive shaft or on the position indicator (2) must be horizontal to the longitudinal axis of the actuator in the closed position.

ACTUATORS - RP SERIES 5 . 0 C O M M I S S I O N I N G If the unit has been left in the same position for long periods, the packings and seals may have set. This means that when the actuator is again operated, possible leakage may come from the piston seals or rod packings. - Page 16 ACTUATORS - RP SERIES 6.1 DISASSEMBLY When disassembly of actuator is required for maintenance, firstly remove the actuator from the valve before performing any disassembly operations. It is important to verify that the actuator is not pressurised. Always use caution and double check that the ports 2 and 4 are vented and are free from any accessory and/or device.

Page 20: Lifting And Handling
Typical operation of the actuator involves applying pressure to the appropriate pressure inlet(s) of a double acting or spring return cylinder by means of a suitable control valve. APV-Torqturn actuators are sized to ensure the required valve torque is produced at the supply pressure selected by the customer. -

ACTUATORS - RP SERIES The standard rotation (when port 4 is pressurized or for spring action) is clockwise to close. When port 2 is pressurized, counter-clockwise rotation is obtained. Torqturn actuators can be supplied with different types of assembly/rotation direction depending on the type of required operation and/or installation, see technical data sheets. - Page 22 3/2 SOLENOID VALVE OPERATION VALVE OPERATION APV can also supply Namur solenoid valves: 5/2 and 3/2 way in all standard voltages, D.C or A.C. 1.

- Page 23 ACTUATORS - RP SERIES 2. External stroke adjustment A great saving of time is achieved, when mounting the actuator on the valve, through the service friendly adjustment of both end positions with precise cam system. The rotation angle is easily changeable with a special cam system.
- Page 24 ACTUATORS - RP SERIES Three Position Torqturn Actuator Three position Torqturn actuator provides an operation of 0°, 45°, 90° or 0°, 90°, 120° and 180°. The midway position is achieved by a mechanical stop of movement of the 2 auxiliary pistons.
