dEsiGn

EMICO’s EA Series, Aluminium Rack & Pinion, Double Acting and Spring Return Pneumatic Actuators are based on innovative and patented technology.

These actuators feature a top-mount malfunction indicator and open / close stop adjustment as standard.

State-of-the-art engineering has also enabled reduction in size without the loss of torque.

The features and characteristics of these actuators have kept pace with fourth generation pneumaticactuators around the world.

FEaturEs

• Indicator

Visual position indicator to NAMUR standard is convenient for mounting accessories such as limit switch, positioner, etc.

• Pinion

The pinion is high-precision and integrative, made from nickel alloy steel and in full conformance to the latest standards of ISO5211, DIN3337 and NAMUR. Dimensions can be customised. Also available in stainless steel.

• ActuatorBody

The extruded aluminium alloy ASTM6005 body is first hard anodized (40um thick), followed by polyester powder coating (min. 70um thick). Other coatings such as PTFE or nickel plated are available on request.

• EndCaps

Die-cast aluminium is first hard anodized (40um thick), followed by polyester powder coating (min. 70um thick). Other coatings such as PTFE or nickel plated are available on request.

• Pistons

The twin-rack pistons are made from die-cast hard-anodised aluminium. They have symmetric mounting position, long life cycle and fast operation. Rotation may be reversed by simply inverting the pistons.

• TravelAdjustment

Two independent, external travel-stop adjustment bolts allow precise and easy adjustments to ±5° in both open and close positions.

• HighPerformanceSprings

Pre-loaded, coated stainless steel springs are corrosion-resistant and offer longer cycle life. They can be dis-assembled safely and conveniently. Different torque requirements can be accomodated by changing the number of springs.

• Bearings&Guides

These are made from low-friction, long-life engineered plastic material to avoid direct contact between metals and assist with smooth operation. Maintenance and replacement is easy and convenient.

• O-Rings

NBR rubber O-Rings provide trouble-free operation at standard temperature ranges. Viton or Silicone is used for lower or higher temperatures.

StandardRotation(Actuator closed with valve closed):

Air to port A forces pistons outwards, causing springs to compress. The pinion turns counter-clockwise while air is being exhausted from port B. With loss of air pressure on port A, the stored energy in the springs forces pistons inwards. The pinion turns clockwise while air is being exhausted from port A.

ReverseRotation(Actuator closed with valve open):

Air to port A forces pistons outwards, causing springs to compress. The pinion turns clockwise while air is being exhausted from port B. With loss of air pressure on port A, the stored energy in the springs forces pistons inwards. The pinion turns counterclockwise while air is being exhausted from port A.

Pneumatic actuators are available in two versions - double acting and single acting (spring return).

manuaL to actuator opEration

1. Remove handle and other parts, eg. circlip from valve stem, valve travel stop plate, from manual valve.2. If actuator is to be mounted “fail close”, turn valve stem 90° using handle. If “fail open”, then leave as is.3. Fit mounting kit and adapter and bolt up.4. Assemble actuator to mounting kit.5. Test assembled package for open/close operation using compressed air to actuator port.6. Do not insert your hands inside the valve.7. We suggest ensuring clean air supply pipes, especially when the plant is without an air filtration system. 8. A spacer between the actuator and valve will be necessary with fluids at high temperature.

opEratinG conditions

OperatingMediaDry or lubricated air or non-corrosive gas. Maximum particle size should be less than 30um.

AirSupplyPressureMinimum supply pressure is 2.5 Bar. Maximum supply pressure is 10 Bar.
