ROTARY ACTUATOR CORROSION PROTECTION OPTIONS
Body :
Hard Anodized Aluminium : (Standard)
  Special Aluminium alloy is used as a base metal
  Hard Anodizing of Aluminium results in better corrosion protection, surface     hardness and superior wear resistance
  50 µm thickness of the controlled oxidized surface of the alloy comprises     primarily of Aluminium trioxide (Al O ) 2 3 crystals along with Magnesium,     Tungsten Oxides which make the surface chemically inert and extremely hard (in     excess of 45º Rc)
  The surface can withstand all environmental oxidations including, those of     saline, except strong alkaline by the surface (Refer the technical document for     more information)
  The oxidized Aluminium base metal cannot be peeled, making it an extremely     stable surface treatment

Electroless Nickel Treatment : ‘EN’
Nickel is deposited on the aluminium surface by its chemical reaction on the body, which is hard Anodized. This treatment covers the crevices including the threads and the passage hole making the surface absolutely non-porous and corrosion free. Superior corrosion resistance as compared to Hard Anodizing, makes this treatment a suitable choice for corrosive environments. Ideal for external wash.

Epoxy Coated Actuator : ‘CL’
The two pack epoxy coating is done on a Hard Anodized surface of the Aluminium body by the spray technique. It produces a 30µ - 40µ thick layer (only external surfaces). This epoxy coating helps in protecting the actuator from extremely corrosive environments. Choose this option specially for alkaline environments. It is also suitable for environments like Ammonia, Ammonia Liquor etc. ROTEX guarantees 500 hrs. salt spray test.

Pinion :
Electroless Nickel Plated : (Standard)
Standard surface treatment given to the pinion shaft of Steel (EN 8). Adequate for most applications including corrosive environments. The Square drive is machined to meet the close tolerances.

Stainless Steel : ‘8/8M’
Optionally available for aggressive environments. Pinion can also be supplied in SS304/SS316.

3 POSITION ROTARY ACTUATOR
SPRING RETURN CONTROLLED BY LIMIT SWITCH
  The Actuator is suitable for coarse - fine adjustment, typically for batching     operations or processes
  The Actuator has to be spring return
  The operation sequences fixed from full open, partial open to full close
  Infinite intermediate positions are possible with the limit switch
  It can be fine tuned to the application easily
  The settings can be changed at site with ease, by simply adjusting the third cam     provided
  It is applicable for 90° or 180° Any ROTEX spring return Actuator can be     converted into this arrangement by adding ROTEX limit switch along with ROTEX     NAMUR valve type 30138
  The accuracy and repeatability depends upon the air pressure variation, change     in the torque of ball valve, change in density and the pressure of media, etc...     expected range 3% with all considerations
  Refer the Dimension table on page 10
  Refer the Spring Torque tables on page 8

DOUBLE ACTING / SINGLE ACTING
3 POSITION MECHANICAL STOPPER
  The Actuator is suitable for coarse - fine adjustment, typically for batching     operations or processes
  The Actuator has to be Double Acting
  The repeatability is 100% since stopping is by mechanical stoppers. It is     suitable for application calling for the precise fine-coarse adjustment like liquid     filling system
  The Actuator can be switched to one, position from any other position very easily     with the solenoid control. The 3rd position is achieved by the mechanical     stopping of the piston movement, in the return stroke by pneumatic stopper     pistons
  The Intermediate position is present at 20% opening. The opening can be     adjusted as required by the set screw. This is field adjustable
  The Actuator as a standard, works in reverse action, as opposed to conventional     configuration i.e. piston inward stroke opens the valve, and piston outward     stroke closes the valve
  The End Stops (+/- 10 °C) are provided on the closing and opening side of the     Actuator for setting valve closing precisely
  The springs can be provided to bring actuator to mid position as a standard     (optional attachment)
  For the dimension details, contact ROTEX
  Refer the spring torque tables on page 7,8

180 DEGREE ROTARY ACTUATOR
DOUBLE ACTING / SINGLE ACTING
  Suitable typically for 3 way valves, requiring ON-OFF operation. It is available in     both Single Acting (spring return) or Double Acting versions
  The Single Acting 180° Actuator can provide centre off for the 3 way ball valve,     bottom entry by choosing the option, of 3 position
  It can be converted to 3 position 0 - 90° - 180° Actuator for 3 way valves using     ROTEX Limit Switch and NAMUR valve type 30138
  The end stop adjustment is provided for opening and closing direction as a     standard
  Actuator mounting is as per ISO 5211 and accessories to NAMUR
  For weight and air consumption data, refer table on page 7 Refer dimension on     page 10
  180° Actuator has 50% of torque value, of that of 90°Actuator

REGULATING ACTUATOR
ELECTRO PNEUMATIC POSITIONER
  Backlash free operation between rack and pinion makes ROTEX Actuator     suitable for regulation duty coupled along with positioner (pneumatic or     Electro-Pneumatic)
  Long life of the Actuator seals, the non wearing characteristic of the mechanical     parts ensure that the control action is maintained, over the life time of the     Actuator
  It can be coupled along with the various types of valves (Ball, V Port Ball or Plug,     Segment Ball, Butterfly, Plug) or louvers and dampers for variety of applications
  Typical control schemes along with the regulating Actuator includes provisions     for:
    1. Air failure safety includes stay-put or fail safe operation, like full close or full     open
    2. Power failure safety, including stay-put or fail safe operation, like full close or     full open
    3. Both air & power failure safety, including above
