FOREWORD
The 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).
The following standards/technical specifications also apply:
- 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
- UNI CEN/TS 764-6:2005 Pressure equipment Part 6: Operating instructions structure and contents.
Below you will find the safety instructions, the minimum information for storage / warehousing, the installation, the commissioning,
the maintenance and the instructions for disposal of products at the end of their life cycle for the pneumatic actuators: ACTUATECH
disclaims any liability for damage caused by improper use, even if partial, respect to the information contained in this manual.
1. GENERAL FEATURES
The GD08 is a part turn pneumatic actuators for valve remote control.
This actuator is available only on Double Acting "GD" version.
- The principle of the actuator application is to open and close the connected valve, without the manual operation with lever or hand
wheel, by means of an electric-pneumatic connection on remote control.
- Scotch – Yoke is a mechanical system that allows to transform the linear force into a rotary torque.
ACTUATECH applies the scotch - yoke system for its actuator production to transfer the pistons linear force to a driving shaft torque.
This system provides a long working life and best performance with the minimum energy consumption.
-The maintenance should be done by ACTUATECH trained personnel only.
This instruction manual contains important information regarding the ACTUATECH Scotch-Yoke pneumatic actuator operation, instal-
lation, maintenance and storage. Please read carefully before installation and keep it in a safe place for further reference.
2. WORKING CONDITIONS
a) Construction
Standard ACTUATECH actuators are suitable for indoor and outdoor installation. The laser marking or a printed label on the actuator
body gives the actuator technical characteristics: type, size, operating pressure, output torque, operating temperature, flange con-
nection, product code and production date. (see drawing pag.5).
b) Motive energy
The operating media should be dry and filtered compressed air not necessarily lubricated or inert gases compatible with internal
actuator parts and lubricants.
The operating medium shall have a dew point equal to – 20 °C or, to be at least, 10 °C below the ambient
temperature (ISO 8573-1, Class 3). The maximum particle size shall not exceed 40 μm (ISO 8573-1, Class 5).
c) Supply operating media pressure
The maximum supply pressure is 8,4 bar (120 psi)
Nominal supply pressure is 5,6 bar (80 psi), working pressure range from 2,5 bar (36 psi) up to 8,4 bar (120 psi).
d) Operating temperature
Actuator standard working temperature range from –20°C (-4°F) to 80°C (176°F)
For low and high temperature versions please contact ACTUATECH. For high humidity and low temperature application are recom-
mended to use a supplementary protection (e.g. screens, sheds or integral painting).
