Replacing the valve block
The valve block, controller and electronic function module make up the control unit of the linear actuator. The four
individual valves form a single unit together with the valve base, and move the linear actuator to the required travel
position. This enables additional travel to intermediate positions within the travel range.
The valve cable assembly and the connections on the valve block are numbered.
If the numbers are no longer legible, mark the pilot lines before detaching them from the valve block.
When connecting, make sure that the numbers on the pilot lines match the numbers of the connections on the valve
block.
