SSF SERIES

FEATURES


STAINLESS STEEL ACTUATOR

INTERNALS

• All internals are direct replacement to ECF

• All the seals are common for ECF, SSF

• Springs & Spring rating are as per the ECF

PISTON WITH RACK

• Double rack and pinion construction

• Hard Anodized pistons • CF8M piston on request• NBR as standard and PE on

request

CF8M BODY, COVER

1

OPTIONAL

• Polyethylene seals for an extremely long life• Low friction, areas retaining grooves provides non stick

slip movement• Life over 3 million cycles• The groove design is common for NBR & PE seals.

The alternative seals can be installed at later date.• Highly recommended for high cyclic operation application• Additional lubrication is not required

•


SUPER SEAL

PROPERTIES

• Needs proficiency in Installation• Due to higher hardness of material

leakage up to 0.001 N l / mincan be observed

‘V’ SEAL

• Unique ‘v’ seal• Low on co-efficient of friction• Long life, no lubrication needed• Excellent response to control

valve positioning due to low friction

• Body bore finish Ra < 0.2 µ Rp < 2.0 µ

o• Low temp rature range : -55 C, Needs low temperature grease

o• High temperature range : +110 C• Non lubricated media like dry

nitrogen• Hydraulic media can be used up

to 12 bar• Can handle dirt & moisture

APPLICATION

1

Pinion:

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.

Electroless Nickel Plated: (Standard)

The two pack epoxy coating is done on a Hard Anodized surfaceof 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.

Epoxy Coated Actuator: ‘CL’

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.

Electroless Nickel Treatment: ‘EN’

• 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

Hard Anodized Aluminium: (Standard)


ROTARY ACTUATOR CORROSION PROTECTION OPTIONS

Body:

Optionally available for aggressive environments. Pinion can also be supplied in SS304/SS316.

Stainless Steel: ‘8/8M’

Actuator is suitable for coarse - fine adjustment, typically for batching operations or processes

Actuator has to be spring return

operation sequences fixed from full open, partial open to full close

Infinite intermediate positions are possible with the limit switch

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

Actuator is suitable for coarse - fine adjustment,

typically for batching operations or processes

The Actuator has to be Double Acting

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

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

End Stops (+/- 10 °C) are provided on the

closing and opening side of the Actuator for setting valve closing precisely

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

Suitable typically for 3 way valves, requiring ON-OFF operation. It is available in both Single Acting(spring return) or Double Acting versions

Single Acting 180° Actuator can provide centre off for the 3 way ball valve, bottom entry by choosing the option, of 3 position

can be converted to 3 position 0 - 90° - 180° Actuator for 3 way valves using ROTEX Limit Switch and NAMUR valve type 30138

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 7Refer dimension on page 10

180° Actuator has 50% of torque value, of that of 90°Actuator

FEATURES

•

•

•

•

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
