INSTALLATION & HYDRAULIC REQUIREMENTS
4.1
Pre-installation
Note: Prior to mounting, actuator assembly must be checked for any damage.
Damaged parts must be replaced by original spare parts.
Verify the actuator
’
s nameplate to ensure that actuator type, model number, force output are correct
before installation or use.
Check if the hydraulic control pressure corresponds with your system specification and the information on
the actuator type plate.
4.1.1 Actuator application
ECON hydraulic actuators are used for operation of Globe valves and Valve Chests. The actuators are
designed for severe operating conditions. For use in extreme conditions e.g. aggressive, corrosive
environments it is recommended to mention this at the ordering stage, in order to verify if the actuator is
suitable. The installation designer is responsible for the hydraulic actuator selection and must determine
if the actuator is suitable for the working conditions.
ECON hydraulic actuators are also available for submerged application up to 50 mt depth.
For submerged application a shaft cover should always be placed on top of the actuator to avoid water
from penetrating the assembly through the actuator shaft.
4.1.2 Actuator orientation
The actuator can be installed in any position on to the valve, however it can be that the complete valve
assembly is not allowed to be mounted in vertical position because of valve specifics. Check the valve
specifications before installing.
When the actuator has an Electric Hydraulic Powerpack there can also be restrictions in installing the
assembly. Check the Powerpack specifications before installing.
4.1.3 Actuator Installation
The handling and transportation of actuators must be carried out with extreme precaution and using the
necessary and adequate means depending on their size and weight in order to avoid risks to the
operators handling them.
All ESL/EDL actuators will be delivered in combination with a globe valve or valve chest. This because of
specialized mounting and adjusting procedure of the valve.
Actuators should be installed in such a way that they are easy to access in order to do the periodic
inspections and corresponding maintenance operations necessary to guarantee the performance qualities
that they have been designed for.
