Lexair”s Magna-Cycle magnetically detented four-way control valve is a spool-type, air-pilot actuated valve. An adjustable permanent magnet in each actuating chamber holds the spool in position until the pilot pressure exceeds the holding power of the magnet. This magnetic detent action in the actuating chamber enables automatic control actions to be consistently and reliably repeated without the need for an electrical or mechanical interface, making it a good fit for hostile or potentially explosive environments. Constructed of corrosion-resistant solid brass, the load-sensing, manifold-mounted valve features a precision lapped fit stainless steel spool. It is subplate mounted with port sizes from ¼” to ½” NPT or SAE and has a pneumatic pressure rating of 150 PSI.
