3 DESIGN EMICO s E Series, luminium Rack & Pinion, Double cting and Spring Return Pneumatic ctuators 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 pneumatic actuators around the world. FETURES Indicator Visual position indicator to NMUR 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 ISO, DIN333 and NMUR. Dimensions can be customised. lso available in stainless steel. ctuator ody The extruded aluminium alloy STM00 body is first hard anodized (40um thick), followed by polyester powder coating (min. 0um thick). Other coatings such as PTFE or nickel plated are available on request. Caps Die-cast aluminium is first hard anodized (40um thick), followed by polyester powder coating (min. 0um 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. Travel djustment Two independent, external travel-stop adjustment bolts allow precise and easy adjustments to ± in both open and close positions. High Performance Springs 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. earings & 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 NR rubber O-Rings provide trouble-free operation at standard temperature ranges. Viton or Silicone is used for lower or higher temperatures. 3 EMICO E SERIES SR & D PNEUMTIC CTUTORS

6 OPERTING PRINCIPLES Pneumatic actuators are available in two versions - double acting and single acting (spring return). DOULE CTING Standard Rotation (ctuator closed with valve closed): ir to port forces pistons outwards, causing the pinion to turn counterclockwise while air is being exhausted from port. ir to port forces pistons inwards, causing pinion to turn clockwise while air is being exhausted from port. Reverse Rotation (ctuator closed with valve open): ir to port forces pistons outwards, causing the pinion to turn clockwise while air is being exhausted from port. ir to port forces pistons inwards, causing pinion to turn counterclockwise while air is being exhausted from port. SPRING RETURN Standard Rotation (ctuator closed with valve closed): ir to port forces pistons outwards, causing springs to compress. The pinion turns counterclockwise while air is being exhausted from port. With loss of air pressure on port, the stored energy in the springs forces pistons inwards. The pinion turns clockwise while air is being exhausted from port. Reverse Rotation (ctuator closed with valve open): ir to port forces pistons outwards, causing springs to compress. The pinion turns clockwise while air is being exhausted from port. With loss of air pressure on port, the stored energy in the springs forces pistons inwards. The pinion turns counterclockwise while air is being exhausted from port. EMICO E SERIES SR & D PNEUMTIC CTUTORS

The right bolt is for the valve closed position adjustment at 0 with ±. The left bolt is for the valve open position adjustment at 0 with ±.

If actuator is to be mounted fail close, turn valve stem 0 using handle. If fail open, then leave as is. 3. Fit mounting kit and adapter and bolt up. 4. ssemble actuator to mounting kit.. Test assembled package for open/close operation using compressed air to actuator port.. Do not insert your hands inside the valve.. We suggest ensuring clean air supply pipes, especially when the plant is without an air filtration system.. spacer between the actuator and valve will be necessary with fluids at high temperature. OPERTING CONDITIONS Operating Media Dry or lubricated air or non-corrosive gas. Maximum particle size should be less than um. ir Supply Pressure Minimum supply pressure is. ar. Maximum supply pressure is ar. Operating Temperature Standard (NR O-Ring): -0 C~+0 C. Low Temperature (Silicone O-Ring): -3 C~+0 C. High Temperature (Viton O-Ring): - C~+ C. Travel djustment djustment range of ± for and rotation. pplication Indoor and outdoor. EMICO E SERIES SR & D PNEUMTIC CTUTORS

11 SPRING PCKS FOR SPRING RETURN CTUTORS Springs Springs Springs Springs Springs Springs Springs Springs MINTENNCE It is recommended that periodic checks be carried out to ensure that all fasteners remain tight. The actuator is supplied ready-lubricated with no further lubrication required. If lubrication is deemed necessary, use EP- grease or local equivalent. Under certain working conditions (heavy duty, non-compatible operating media or abnormal working conditions), it is recommended that internal seals be checked periodically and replaced when necessary. On spring return actuators, spring fatigue may set in, requiring replacement. Springs should always be replaced in full sets. NOTE: Under normal working conditions, the actuators will be maintenance-free as it has been lubricated to last a normal working life. Should it become necessary to replace seals, please contact us for assistance. Kits and Instructions are available to customers on request.
