Solenoid valves
An overview of the built−in solenoid valves (3), their functions, positions and control number are
delivered.
Valves can (as required) be mounted with or without regulator (5) for regulating the air−cylinder
speeds, pressure or amount.
The solenoid valves have LED indications (9) that light up while controlling the valve but do not
indicate whether the function is carried out.
Risk of injury!
By manually switching a solenoid valve an unexpected movement of, for example,
a cylinder may lead to injuries. Nobody may be near this movement.
For service activities a solenoid valve may be manually operated with knob (8).
7.6.3
Set the pressure regulator on a solenoid valve
A regulator (5) can control the piston speed of an air cylinder, pressure or amount.
A lower setting reduces the noise.
METHOD
Loosen lock nut (6).
Increase pressure: turn set screw (7) clockwise.
Reduce pressure: turn set screw (7) counter−clockwise.
Tighten lock nut (6).
If provided, correct the pneumatic settings of the cylinder involved, see
next page.
