Present User’s Installation and Maintenance Manual has been edited in conformity with:
- 2006/42/EC Directive “Machinery”;
- 2014/34/UE Directive “Equipment and protection systems designated to be used in potentially explosive atmospheres” (ATEX);
Following standards/technical specications also applied:
- EN 15714-3:2009 Industrial valves: Actuators – Pneumatic part-turn actuators for industrial valves;
- IEC 61508:2010-1/7 Functional safety of electrical/electronic/programmable electronic safety-related systems. Part 1÷7;

1. GENERAL FEATURES
ACTUATECH manufactures a wide range of part-turn pneumatic actuators for valve remote control.
Actuators are available on Double Acting (DA) and Spring Return (SR) versions.
Main actuator purpose is to open and close valves using an electric-pneumatic connection on remote control, without any manual
operation (lever or hand wheel).
RP actuators use a Rack & Pinon kinetics to transform a rectilinear motion generated by pistons into a shaft rotational motion 0°÷90°.
Standard actuators (DA and SR) have a clockwise rotation (CW) direction to close the valves (0° closed valve, 90° opened valve), but
counter-clockwise rotation (CCW) versions (0° opened vale, 90° closed valve) are available too.
Double acting (DA) Rack & Pinon actuators have a double constant rectilinear torque curve, while Spring Return (SR) Rack & Pinon
actuators have a decreasing rectilinear torque curve.
The components for the actuator maintenance are supplied in the ACTUATECH spare part kit (see section 9 exploded views).
Actuators maintenance should be done by ACTUATECH or trained personnel only (see section 10).
This instruction manual contains important information regarding operation, installation, maintenance, and storage of ACTUATECH
actuators. Please read it carefully before installation and keep it in a safe place for further reference.
Actuators are components without dened and proper functionality.
Below you will nd the safety instructions, minimum information for storage / ware cylinder, installation, commissioning, maintenance
as well as instructions for products disposal at the end of their life cycle.
ACTUATECH disclaims any liability for damage caused by improper use, even if partial, respect to the information contained in this manual.

5. FUNCTIONNING
Below described the main operating conguration. In case your product does not meet the following schemes, please look at
ACTUATECH catalogue or contact us.
5.1 Double acting (DA) actuator
Supplying air into port (2) actuator shaft rotates counter-clockwise (CCW) to open the valve. Conversely, supplying air into port (4)
actuator shaft rotates clockwise (CW) to close the valve.
5.2 Spring Return (SR) FAIL TO CLOSE
Supplying air into port (2) pistons move outward compressing the springs and actuator shaft rotates counter-clockwise (CCW) to open
the vale. Closing action is realized stopping air feeding. Springs energy push pistons back and consequently shaft rotates clockwise
(CW).
To avoid dust or solid particles incoming, close port (4) using a cap. In case of explosive environment use protection caps in complian-
ce with National safety/technical Standards or Regulations.

ce with National safety or technical Standards.
5.4 Connection diagram
Remote operation control should be done connecting a direct solenoid valve to VDE/VDI 3845 NAMUR plate or connecting a piping
system directly to ports (2) (4). Use an independent electric control cabinet.

Before actuator installation check its conditions to verify eventually failure during transport and/or storage.
Actuator purpose is a remote control of a valve (opening and closing actions) avoiding manual operations. Actuator uses air or gas
controlled by a mechanic, pneumatic or electropneumatic valve. Size actuator choice might be affected by system design, chemical/
physical ow and environmental conditions, consequently higher safety factor can be required.
- Carefully read this instruction manual and the handbook included in the box.
- Take care of actuator features limit indicated on the labels to ensure the suitability.
Please verify actuator/valve conditions according to the above safety warnings and strictly follow the below indications.
- Check actuator position looking at shaft slot orientation;
- Double acting (DA) actuator is always supplied in opened position;
- Fail Close Spring Return (SR) actuator is always supplied in closed position;
- Fail Open Spring Return (SR) actuator is always supplied in opened position;
- Actuator position and rotation must be according to valve requirements and operations, especially for Spring Return (SR);
- Check valve position (open or closed) and its rotation direction;

7.1.2 Plate installation
If a direct installation is not possible because of discrepancy between actuators and valve anges or because of power transmis-
sion differences, is it possible to use plates. Adapting plates make the installation easier and offer more space for actuator/valve
installation.
7.1 Valve/Actuator installation
7.1.1 Direct installation
Direct installation is the best solution to avoid play or clearance between valve and shaft. Direct installation needs same anged
standard connection on valve and actuator as well as same dimension of valve stem and actuator socket.
Installation:
A. Pull reduction in valve stem (in case of reduction needs only);
B. Put valve stem into the actuator socket;
C. Verify correct connection to avoid play, clearance or interferences in between;
D. Place screws (1) and relevant washers (2) and screw them in compliance with below torque
indications;
E. After installation, check actuator rotation direction for Double acting (DA) actuators;
F. After installation, check actuator rotation direction and home position in case of Spring Return (SR);
G. In case of discrepancy contact us;
Installation:
A. Place plate (3) on valve ange;
B. Pull reduction in valve steam (in case of reduction needs only);
C. Put valve stem into the actuator socket;
D. Verify correct connection to avoid play, clearance or interferences in between;
E. Place screws (1) and relevant washers (2) and screw them in compliance with below torque
indications;
F. After installation, check actuator rotation direction for Double acting (DA) actuators;
G. After installation, check actuator rotation direction and home position in case of Spring Return (SR);

7.1.3 Bracket & Joint Installation
Bracket & Joint installation is suitable in case of valves/actuator space requirements, in presence of non-standard valve ange or
valve stem, or generally in case of actuator/valve installation impossibility. Bracket is a stainless-steel drawn tubular with two holes
for Joint passage and several holes for valve/actuator installation. Joint allows the connection of actuator shaft and valve stem.
Bracket & Joint play or clearance must be as low as possible to ensure a correct actuator/valve power transmission.
Torque indication
ACTUATECH actuator, with evacuation grooves on connection side is purposely designed to a direct installation. Evacua-
tion grooves avoid any actuator damages caused by eventual draining uids coming from valve stem.
Installation:
A. Place Bracket (4) on valve ange, ribs must be perpendicular to the pipe;
B. Place screws (1) and relevant washers (2);
C. Place nuts (7) and washers (8) and in correspondence to the screws;
D. Lock the nuts using a wrench and screw them in compliance with below torque indications;
E. Put valve stem into the joint socket (3);
F. Put joint stem (3) into the actuator socket;
G. Verify correct connection to avoid play, clearance or interferences in between;
H. Place screws (5) and relevant washers (6) and screw them in compliance with below torque
indications;
I. After installation, check actuator rotation direction for Double acting (DA) actuators;
J. After installation, check actuator rotation direction and home position in case of Spring Return (SR);
