NOTE: DATA MAY VARY BY CONFIGURATION. SEE CONFIGURATION SECTION.
Direct-acting, 3-way directional cartridges (1 to 2 open, 3 blocked) are switching devices typically used in moderate
flow circuits. They can be used by themselves or to actuate larger pilot operated directional cartridges or logic
cartridges. The valve shifts when the pressure differential between port 1 and port 4 exceeds the setting.
