The proportional directional valves DHZE-A are used for control the speed and direction of movement of hydraulic cylinder or motor.
Maximum flow: up to 70 l/min (depending on spool type), maximum pressure in P, A, B ports: 350 bar, in T port: 210 bar
The DHZE-A valves are designed to work in open loop. They operate in association with off-board driver, which supply the proportional valves with proper current to align the valve regulation to the reference signal supplied to the driver. The spools are available with linear, progressive or differential flow characteristics.
