Product Details:

Body: Hard Anodized Aluminum : (Standard)

• Special Aluminum alloy is used as a base metal.

• Hard anodizing of Aluminum 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 crystals along with Magnesium, Tungsten Oxides which makes the surface chemically inert and extremely hard (in excess of 45 °Rc).

• The surface can withstand all environmental oxidations including, those of saline, except strong alkaline by the surface.

• 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 eopxy coating is done on a Hard Anodized surface of the Aluminium body by the spray technique. It produces a 30µ- 40µthick 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 etc. ROTEX guarantees 500 hrs. salt spray test.

Pinion :

Electroless Nickel Plated: (Standard)

Standard surface treatment given to the pinon shaft of Steel (EN 8).
Adequated for most applications including corrosive environments.
The square dive 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

Features:

• The actuator is suitable for coarse - fine adjustment, typically for batchnig 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.

Additional Information:

• Item Code: 3PA
• Port of Dispatch: Mumbai

Product Details:

Features:

• The actuator is suitable for coarse -fine adjustment typically
  for batch in go preparation processes.

• The repeatability is 100% since stopping is by mechanical stoppers.
  It is suitable for application calling for precise fine coarse adjustment
  like liquid filling system.

• The actuator can be switched to one position from any position very
  easily with the solenoid control.

• The 3rd position is achieved by theme chanical 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 standard works in reverse action as opposed
  to conventional configuration i.e. piston inward stroke opens the
  valve & piston outward stroke closes the valve.

• The end stops (+/- 10°) are provided on the closing & opening side
  of the actuators for setting valve closing precisely.

• The springs can be provided to bring actuator to mid position
  as a standard(optional attachment).
