Pneumatic Actuators PRODUCT’S SIZE:
structural feature and technical characteristics:
Structural feature
Dual-piston driven, toothed bar and gear driven, structure is compact, position of assembly is symmetrical, motion is swift, turning of output axis can be changed through simple reversal of piston. Output of angle travel:0°~90°.DA stands for dual action; SR stands for single action; namely type of spring return.

Cylinder body

Extruded aluminum alloy cylinder body. The surface is treated by anticathode oxidation which greatly improves the rigidity and anti-corrosion. The internal surface of cylinder is honed and processed so that the fricition coefficient is low and the service life is long.

Baring

The output axis and the piston have chosen high quality bearing which have good stability and sealing, low friction coefficient, large range of applicable temperature and long service lift.
“O”Seal ring Common type: nitrile butadiene oil resistant rubber. Fluoroelastomer and silicon rubber are used in applicable situation of high and low temperature. Use relevant lubricant.

Regulation of stroke

There are two individual travel set screws on the front face of the cylinder body, the travle can be adjusted ±5°exactly between 0° and 90° location which keeps in line with the open and close position of the valve.

Multi funcational indicator

Inside there are 4×4 standard groove and M6 internal screwed hole which can be smartly mounted with accessories and all-purpose sensor. Embedment of different colors makes visual feeling clear. Embedment of stainless steel is used to install accessible sensor.

Output axis

There are inner octagonal hole at the lower end which accord with ISO05211/DIN3337 and can be expediently carried out interchange of parallel square and diagonally square. Key connections which appointed by users can be available.
Air port Accord with VDI/VDE3845NAMUR, criterion which can be simply and easily mounted with solenoid valve.

Design of single return
The operation organ of single and dual action have the same cylinder bodies and end shields. It is assembled type pre-load spring qroupware. By increasing or removing spring and realizing scene conversion.

Mounting hole

Top mounting hole accords with VDI/VDE3845 which can mounted with locator limit switch box. Bottom mounting hole accords with ISO05211/DIN3337 which can easily mounted with valve, manual organ or bracket.
Operation principle and rotation direction:
when pressure of air supply enters from port 2and forces pistons to detach and move toward direction of end shields,

► Operating conditions-Pneumatic Actuator

Position Indication:
The Actuatorvalve position is shown via a color-coded insert and NAMUR slot. The indicator is suitable for either direction of actuator rotation, and drive shaft size.
Actuator Drive:
The NAMUR drive slot on the position indicator permits direct drive engagement of switch boxes and positioners.
Direct Mounting of Sensors:
The indicator can be supplied with metal inserts to allow for easy installation of many types of sensors.
Operating Media:
Dry or lubricated air or inert n-corrosive gases on condition that they are compatible with wetted internal actuator parts and lubricant. The operating media dew point must equal either -20C(-40F) or 10C below the ambient temperature. The maximum particle size must not exceed 30 microns.
Supply Pressure:
For Double Acting and Spring Return actuators the maximum supply pressure is 8 bar(116 psi). The minimum supply pressure is 2.5bar(40psi).
Operating Temperature:
Normal temperature (NT) actuator with NBR”O-rings” from -20C(+4 F) to +80C(+176 F).
Low temperature (LT) actuator with Silicon “O-rings” from -50 C (+58 F) to +80C (+176 F).
High temperature(HT) actuator with FPM “O-rings” from -15C(+5F) to +150C(+300 F).
CAUTION: For high and low temperature service special grease is required. High and low temperature will vary the output torque of the actuator. Please contact a ROPO sales representative for each application.
Stroke: See technical data
Standard construction: 90 degree rotation with stroke adjustment at 0 degree; And 90 degree +/ – 4 degree; .
Operating Time: See Technical Data Sheet.
Lubrication:
The ROPO Rack and Pinion Actuator comes factory lubricated for the life under normal operating conditions. The standard lubricant is suitable for use from -50C (58 degree ) +80C (+176 degree ). For high and low temperature service where special grease is required please contact a ROPO sales representative.
Construction:
Durable twin piston rack and pinion actuator design is suitable for both indoor and outdoor applications.
