5/3-way solenoid valve, centre position pressurised, G 1/4", 850 l/min, 24 V AC, aluminium

This 5/3-way solenoid valve operates double-acting pneumatic cylinders and adds a third switching position compared with a 5/2-way valve. With the coil de-energised both working ports are pressurised, so the piston stays loaded from both sides and resists external forces. Flow reaches 850 l/min at a nominal width of 4.8 mm, and every port is threaded G 1/4". The body and spool are made of aluminium, the seals of NBR. At 5 bar the switching time stays below 50 ms and service life is at least 40 million cycles.

Benefits

• Flow rate of 850 l/min at a nominal width of 4.8 mm
• Pressurised centre position keeps the piston loaded during a power failure
• Service life of at least 40 million switching cycles
• Protection class IP 65 and a voltage tolerance of ± 10 %
• Aluminium body and spool combined with NBR seals
• Power consumption of 4 VA at 24 V AC

Applications

• Double-acting cylinders that must hold their position when power is lost
• Clamping and fixture systems in machine tool construction
• Lifting and conveying equipment with G 1/4" ports
• Assembly machines running up to 3 switching cycles per second
• Test benches supplied with lubricated or non-lubricated filtered air

Standards and conformity

The solenoid coil meets protection class IP 65. The permissible control voltage tolerance is ± 10 % referred to 24 V AC.
