What kind of pressures can they handle? Quick releasing? Standard plumbing style fittings?

Thanks.
The 5/2 valves are suitable for low pressure pneumatics (10bar). They are electrically driven and operate in about 300ms. They use 1/4 fittings not standard plumbing fittings. A 5/2 valve allows a double acting cylinder to be used (push/pull cylinder) but you can blosk off one of the ports to make a 3/2 valve which will allow you to use a single acting cylinder.
