HAWE North America Inc. Pressure Controlled 2-Way Directional Circulation Valve CNE 23

The pressure controlled 2-way directional valve automatically switches one (low pressure) of two circuits feeding a hydraulic system into idle circulation as soon as the adjusted pressure is achieved or exceeded by the high pressure circuit. The valve is retained in this shifting position, enabling idle circulation, via the higher pressure being picked up and transmitted by a control oil duct. This valve also serves as a pressure limiting valve for the low pressure circuit. Contrary to version CNE 2, CNE 21 features an additional thread seal and CNE 22 and 23 a thread seal plus a piston seal. The idle circulation valves type CNE are screw-in valves where the mounting hole can be easily manufactured.
