The 3FREZ10B-1X/80L2G24-27Z4MM valve is manufactured by Bosch Rexroth within the 3FRE Flow Control Valves series. It regulates hydraulic flow in automated machinery by proportionally shifting the spool to follow an electrical command. The unit operates in position control mode so that spool travel matches a setpoint signal of 0 to +10 V. A linear flow characteristic ensures that output is directly proportional to the command. The valve accommodates a maximum working pressure of 250 bar and fits the NG10 size interface. Three flow ways permit metering between pressure, actuator, and tank lines, while a 24 V DC supply energizes the integrated electronics.
For installation, the valve bolts to a subplate using the ISO 4401-05-04-0-94 pattern, and an inductive position transducer monitors spool displacement for feedback accuracy. Electrical power and command lines terminate through a 6P+PE interface that mates with a DIN 43563-AM6 plug connector. The flow path contains no internal non-return valve, so reverse flow must be handled externally if required. NBR seals isolate hydraulic passages and suit systems that run on mineral oil types HL or HLP specified in DIN 51524. This mounting and connection arrangement supports compact manifold layouts in hydraulic automation.
