5/3-way solenoid valve, mid-position exhausted, G 1/4", 850 l/min, 24 V DC, aluminium body

This 5/3-way solenoid valve controls double-acting pneumatic cylinders in applications that require a pressureless rest position. In the centre position both working lines are vented through the two G 1/4" exhaust ports, which leaves the piston rod free of force and movable by hand. A nominal width of 4.8 mm produces a flow rate of 850 l/min, enough for cylinders with a large swept volume. Body and spool are made of aluminium and the seals of NBR, with an operating pressure range of 1.5 to 8 bar. At 24 V DC the pilot stage draws only 3 W.

Benefits

• Flow rate of 850 l/min at a nominal width of 4.8 mm
• Vented centre position releases both working lines through two G 1/4" exhaust ports
• Switching time below 50 ms at 5 bar, up to 3 cycles per second in the 5/3-way version
• Service life of at least 40 million switching cycles
• Aluminium body and spool, NBR seals, polyamide pilot stage
• Power consumption of just 3 W at 24 V DC with a voltage tolerance of ± 10 percent

Applications

• Double-acting cylinders in assembly and clamping fixtures that must stand depressurised at standstill
• Handling and gripping equipment where operators intervene manually in the rest position
• Packaging machinery with cylinders requiring up to 850 l/min of air
• Test rigs and special-purpose machines whose piston rod has to stay free after shutdown

Standards and conformity

With the coil fitted and the plug attached, the valve housing reaches protection class IP 65. The control voltage may deviate from 24 V DC by ± 10 percent.
