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 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 - 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 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.
