Rexroth 4WEH16 Electro-Hydraulic Directional Valves

Rexroth 4WEH16 Electro-Hydraulic Directional Valves are directional spool valves with electro hydraulic actuation. The control the start, stop and direction of a flow. These directional valves basically consist of the main valve with housing, main control spool, one or two return springs and , as well as pilot valve with one or two solenoids "a"and/or "b". Electro Hydraulic Directional Control Valve 2 Spool Positions is the combination of the electrical operated directional control valve and the hydraulic operated directional control valve. Electro-Hydraulic Directional Valve 2 Spool Positions uses the electrical operated directional control valve to control the hydraulic operated directional control valve, and change the hydraulic oil direction.
