5/3-way solenoid valve, sub-base type, closed centre, G 1/8", 700 l/min, aluminium

The 5/3-way solenoid valve with closed centre stops a double acting cylinder in any intermediate position because both working lines are blocked at rest. Two G 1/8" ports pass 700 l/min, which is enough for cylinders up to roughly 32 mm bore on short strokes. Switching takes less than 15 ms and the 5/3-way function permits up to 3 cycles per second. Built as a sub-base valve, the unit is screwed onto a valve station of an existing terminal, either replacing a failed valve or adding a missing function. Body and spool are made of aluminium, the seals of NBR.

Advantages

• The closed centre holds the load in place even if the signal fails, since both working ports stay shut.
• Service life of at least 40 million cycles at a switching time below 15 ms.
• Power draw of only 0.8 W per solenoid relieves the power supply of a fully populated terminal.
• Operating pressure from 2 to 8 bar in the 5/3-way function matches the usual 6 bar line pressure.
• An LED status indicator shows the applied signal at the valve itself and shortens fault finding.
• Screws and gasket are included, so the exchange needs no extra mounting material.

Applications

• Retrofitting a hold position on handling axes that previously offered two end positions only.
• Replacing a failed valve on an existing terminal without altering the tubing.
• Positioning of folding and swivel units that have to stay put in case of a fault.
• Test and assembly stations with short cycles of up to 3 switching cycles per second.
• Small cylinders with G 1/8" ports in packaging and feeding equipment.

Standards and conformity

The valve reaches degree of protection IP 40. No further approvals are stated for this version.
