4 INSTALLATION AND START-UP
4.1 Securing the 4-way valve
The 4-way valve must be installed on a stable foundation, which must be level and stable, so that the
4-way valve is not twisted or exposed to a ±0.1 mm profile distortion.
Bolts must be tightened in accordance with supplier’s instructions.
Ensure that the flow direction is correct before assembly.
The 4-way valve’s end stop can only be used as a stop when operating with manual handle bar. When
activated with a cylinder, the cylinder’s own end stop is used.
4.2 Adjusting the 4-way valve
The cone in the 4-way valve can be adjusted by turning the set screw (Pos.2):
• Clockwise
to lift the cone.
• Counter clockwise
to lower the cone.
It is important to lock the screw after adjustment by tighten the nut (Pos.1) clockwise.
If the 4-way valve is blocked, it is possible to adjust the cone.
