The ASCO Series 543 is a family of ISO 5595/1 pneumatic solenoid spool valves.
The valves are designed for reliable, long service life of 30 million cycles. Compact models and options for ATEX zones 1/21 and 2/22 are available. They are suitable for applications such as packaging. For improved product performance, wider range of options and shorter lead times, select an AVENTICS ISO valve instead.
