The 4WE6D73-6X/OFEG24N9K4/A12V/62 valve is part of the WE Directional Spool Valves series from Bosch Rexroth, and it directs hydraulic flow in automated machinery. A coil rated at 24 V DC links the valve to standard control cabinets, while a rated current of 1.25 A ensures consistent magnetic force during every shift. Electrical demand is fixed at 30 W, and the 100 % duty cycle allows continuous energization without overheating. A voltage tolerance of ±10 % lets the valve remain functional when supply levels drift, and the DIN EN 175301-803 (K4) connector provides a common plug interface for rapid field replacement. Ingress protection is IP65, so dust and low-pressure jets cannot reach live parts when the gasket is in place. The assembly weighs 1.95 kg with both solenoids fitted, making it light enough for single-person mounting on compact manifolds.
The sub-plate face follows the ISO 4401-03-02-0-05 porting pattern, which positions pressure, work, and tank ports for interchangeability across modular stacks. Working ports P, A, and B withstand operating pressures up to 350 bar, while the tank port endures 210 bar so return lines can run at elevated back-pressure. A manual override is included, but it must not be used if tank pressure exceeds 50 bar. The flow path accommodates up to 80 l/min under direct current actuation, and a maximum switching frequency of 4.2 cycles per second governs the response rate in servo loops. Accurate manifold alignment is maintained by a locating hole and an ISO 8752-3×8-St spring pin, reducing the risk of port mismatch. FKM seal material withstands high temperatures and aggressive hydraulic oils, promoting long service life in harsh production environments.
