Description:
Rexroth Proportional Valve 4WREE10W1-50-2X/G24K31/A1V is a high
performance industrial hydraulic valve manufactured by Bosch
Rexroth. It is a direct-acting proportional directional control
valve with electrical position feedback and integrated electronics
(OBE) to precisely control the direction of oil flow. The valve is
operated via a proportional solenoid using a spring-centered
control slide and is designed to comply with the interface mode of
ISO 4401. The maximum operating pressure is 315 bar and the maximum
flow rate is 180 l/min.
Fields of application:
Machine building industry: In CNC machine tools, this proportional
valve can be used to precisely control the feed speed and direction
of the machine tool, improving machining accuracy and efficiency.
For example, in the machining of complex parts, by precisely
controlling the speed and direction of tool movement, the
dimensional accuracy and surface quality of the machined parts are
ensured.
Aerospace: Aerospace equipment requires a high degree of precision
and reliability in hydraulic systems. The proportional valves can
be used in aerospace hydraulic systems for flight control surface
actuation, landing gear retraction and other key parts. For
example, in the process of landing gear retraction and release, the
proportional valve can accurately control the flow and direction of
the hydraulic fluid to ensure the smooth retraction and release of
the landing gear and ensure flight safety.
Metal smelting and processing industry: In the steel mill hydraulic
machinery, it can be used to control the rolling force and roll
position of the rolling mill to improve rolling quality and
production efficiency. For example, in the hot rolling process,
through precise control of the position and pressure of the rolls,
to ensure the dimensional accuracy and mechanical properties of
steel.
Plastics and rubber processing industry: in the plastics machinery
and die-casting machinery, the proportional valve can be used to
control the injection speed and pressure of the injection molding
machine, as well as die casting machine injection speed and
pressure. For example, in the injection molding process, precise
control of injection speed and pressure can avoid defects in
plastic products and improve product quality.
Paper industry: In the hydraulic system of paper mills, it can be
used to control the pressure and speed of the press rolls of paper
machines to improve the quality and productivity of paper. For
example, during the paper pressing process, the pressure of the
press roll is precisely controlled to remove excess water from the
paper and ensure the strength and quality of the paper.
Oilfield equipment: In oilfield mining equipment, it can be used to
control the action of hydraulic cylinders to realize the mining of
oil wells and the operation of equipment. For example, in the
drilling process, by controlling the action of hydraulic cylinders,
it can realize the up and down movement and rotation of the drill
bit, and improve the drilling efficiency and safety.
Advantages:
Precise control: The proportional valve is equipped with an
electrical position feedback device that monitors the spool's
position in real time and accurately controls the spool's movement
according to the input signal, thus realizing precise control of
fluid flow and direction. Its static/dynamic characteristics are
excellent, with hysteresis less than 0.1%, reversal range less than
0.05%, and response sensitivity less than 0.05%.
Integrated electronic components: Equipped with integrated
electronic components (OBE), it can directly receive voltage or
current signals for control, which improves the control accuracy
and response speed of the system. At the same time, this integrated
design reduces external wiring, reduces the risk of failure and
improves system reliability.
Multiple control modes: It can be controlled by analog signals as
well as digital signals, which provides a high degree of
flexibility. This diversified control mode enables it to adapt to
different control systems and application scenarios.
High reliability: It adopts high-quality materials and advanced
manufacturing process, with high reliability and durability. Its
solenoid coil has a resistance value of 2.65Ω at 20°C, a maximum
thermal value of 4.05Ω, and a maximum coil temperature of 150°C.
Meanwhile, the proportional valve has a protection class of IP65,
which can effectively prevent the intrusion of dust and water, and
adapt to the harsh working environment.
Energy saving and high efficiency: By accurately controlling the
flow and pressure of the fluid, it reduces the energy loss in the
hydraulic system and improves the energy utilization efficiency of
the system. In practical application, it can reduce the energy
consumption of the equipment and lower the operation cost.
Convenient installation: Adopting the base plate mounting method,
which conforms to the interface mode of ISO 4401, it is very
convenient for installation and maintenance. This mounting method
not only saves space, but also facilitates integration and
connection with other hydraulic components.
