ROSS’ new CrossCheckTM CC4 Series Safety directional valve is a redundant, externally monitored 4-ported, 3-position (closed center) pneumatic valve for Category 4, PL e applications, where controlling and stopping a cylinder is necessary for safe operator access during production-related tasks. The valve is constructed with tight-sealing, dirt-tolerant poppet-type valve internals. The CrossCheckTM CC4 Series valve is designed to be controlled by a safety controller or safety relay with dual channel outputs and the capability of monitoring the mid-position feedback sensors. The valve is a redundant valve and is driven by 4 solenoid pilot valves - two for extending and two for retracting.
