4/3 Directional Valve, Solenoid Operated, Spool Type, Direct Acting
4-way, 3-position spool type directional valve with 3/4-16 UNF connection thread, operated by dual solenoids,
designed for installation into A4 (C-8-4) chambers of the block. The valve controls the ๏ฌow direction of the ๏ฌuid,
changes the direction of the hydraulic cylinder piston rod or stops it.
