when the valve is in the normal position and stops
when the forces are in equilibrium
• If there is a signal present at Y1(10) and Y2(10),
outputs 2 and 4 are exhausted, the drive is unpressurised
and can be moved by an external force
• Normally open after output 2
• A double-acting drive connected to outputs 2 and 4
is fed with compressed air via output 2 when the
valve is in the normal position. Output 4 is
• A double-acting drive connected to outputs 2 and 4
is unpressurised when the valve is in the normal
position and can be moved by an external force
• If there is a signal present at Y1(14) and Y2(12),
there is pressure at outputs 2 and 4
• Normally closed (by combining directional control
valve code K and two piloted non-return valves)
• The piloted non-return valves connected to outputs
2 and 4 are unpressurised when the valve is in the
normal position and the pressures in the drive close
the non-return valves leak-tight
• The drive stops when the forces are in equilibrium
• Leakages can only occur via the drive seals
is fed with the same compressed air at both ends
exhausted. The drive is thus in a clearly defined
position in the initial position, as would also be the
case with a single solenoid 5/2-way valve
• If there is a signal present at Y1(14) and Y2(10),
output 2 is exhausted and pressure is fed to output
4. The drive leaves the initial position
• With this 2x 3/2-way valve a closed circuit can be
created by combining it with piloted non-return
valves. However, this is then selected by an active
