Z4WEH22E63-5X/6EG24N9TKS

The Z4WEH22E63-5X/6EG24N9TKS valve belongs to the Z4WE Solenoid Actuation Spool Valves series and is produced by Bosch Rexroth for hydraulic automation circuits. It meters fluid by shifting a spool with an electromagnet and is fitted with a high-power wet-pin coil so magnetic force is transmitted efficiently while the winding is cooled by the hydraulic oil. The pilot coil is rated for 24 V DC, drawing 30 W, which equals a steady 1.25 A and simplifies the sizing of conductors and fuses. Acceptable voltage variation is ±10 %, preventing malfunction during minor supply deviations. Because the duty cycle is 100 % ED, the solenoid may remain energized indefinitely without thermal derating, allowing the valve to hold a flow position as long as the control signal is present.

A concealed N9 manual override lets technicians shift the spool mechanically when electrical power is unavailable. Coil insulation is specified for a surface temperature up to 120 °C, ensuring safe operation during continuous duty in warm environments. Switch-off events can create up to 500 V of overvoltage, so a 48 V suppressor device is recommended to protect driver electronics from that transient. The electromagnet can cycle as often as 15 000 times per hour, supporting high-speed hydraulic machinery that demands rapid on-off actuation without excessive heat buildup or wear.
