The participants shall:
Explain in their own words and share understandings about the function of valves
ELEMENT 6.2 - DIRECTIONAL CONTROL VALVES
Learning objectives:
46) The participants can recognise the function of different types of directional control valves (Knowledge, basic level) 47) The participants can describe the operation of different types of directional control valves (Knowledge, basic level)
