Each and every actuator is individually tested / checked to verify: Output torque (equal or greater than minimum guaranteed value), Functional test (correct operation of control system / electrical apparatus), Recording of stroke speed, Correct coupling dimensions (conformity to valve topworks).
The goal of individual testing is to assure that each and every actuator leaves our factory in perfect working conditions and complies to customer specifications.
All the produced equipment is tested and delivered complete with its own individual pertinent Test Certificate according to EN 102043.1.
Main equipment include a battery of Dynamic (continuous measurements) and Static (step by step) Test Benches with a torque range from 30.000Nm up to 500.000Nm.
The Testing Equipment is supported by an impressive Compressor Station able to guarantee the contemporary performance of up to 7 actuators' PNEUMATIC test.
Installed compressor units allow pressure supplies up to 12bar with a flow rate of 65 litres/sec., and up to 120 bar with a flow rate of 10 litres/sec..
For HYDRAULIC testing DVG disposes of Hydraulic Power Units for a hydraulic supply of up to 350 barg.
Electro-hydraulic Control Units allow to check and inspect the hydraulic actuators, performing complete cycle tests as well as Cleanness Classification in accordance with ISO 4406 and NAS 1638.
Special tests at both low and high temperature (below -40°C, / + 85°C) are carried out in a dedicated climatic chamber
