In
the era of rapid development of modern industrial automation, the
pursuit of precision, efficiency, and stability has become the core
demand of various industries. Against this backdrop, the 50 L/min
low-flow servo valve independently developed and produced by Berlede
(BERD) Company has emerged as a crucial cornerstone component in
precision control systems. It is not merely a functional part that
regulates fluid flow; rather, it serves as the "neural hub" of automated
equipment, accurately translating electrical control signals into
precise fluid power output. This product is widely applicable to
industrial scenarios that have stringent requirements for control
accuracy, such as high-end precision machine tools, collaborative
robots, and minimally invasive medical equipment. Moreover, it has been
successfully integrated into numerous large-scale automation systems,
ranging from intelligent manufacturing production lines to precision
laboratory test platforms, effectively guaranteeing the efficient and
stable operation of equipment and the ultra-high accuracy of core
operations.
The
outstanding performance of the Berlede 50 L/min low-flow servo valve
stems from its advanced core technology and sophisticated structural
design. In terms of servo control technology, the product adopts a
high-response proportional servo control scheme integrated with a
precision feedback sensor module. This scheme enables the valve to
achieve closed-loop control of fluid flow—by real-time collecting the
actual flow data through the built-in high-precision flow sensor and
comparing it with the preset control parameters, the system can
dynamically adjust the spool displacement with microsecond-level
response speed. As a result, it can control the fluid flow with
extremely high precision and long-term stability, effectively avoiding
the flow fluctuation problems that are common in traditional servo
valves under low-flow conditions.
In
terms of structural design, the product has undergone in-depth
optimization for low-flow application scenarios. The valve core and
valve seat are manufactured using a precision grinding process with a
tolerance of less than 0.001 mm, forming an ultra-precise flow channel.
This special flow channel design not only minimizes the flow resistance
under low-flow conditions but also ensures that the fluid flows smoothly
without eddy current, thereby realizing precise control even at an
ultra-low flow rate of 0.1 L/min. Additionally, the product adopts a
modular structural design, which not only facilitates quick installation
and maintenance but also allows for flexible configuration according to
different application requirements, such as matching different types of
connectors and control signal interfaces to adapt to diverse industrial
environments.
Beyond
the core advantages of high precision and high stability, the Berlede
50 L/min low-flow servo valve also demonstrates excellent comprehensive
performance in terms of low noise and low power consumption, bringing
significant value to industrial users. In terms of low-noise design, the
product incorporates a multi-stage damping structure in the valve core
movement mechanism and uses a special wear-resistant and shock-absorbing
seal material. These designs effectively reduce the mechanical
vibration during the operation of the valve core and the fluid impact
noise in the flow channel. The measured noise value is less than 45 dB
under rated working conditions, which is far lower than the industry
average of 60 dB. This makes it particularly suitable for applications
with strict noise requirements, such as medical operating rooms,
precision electronic component manufacturing workshops, and laboratory
environments, helping to improve the working comfort and safety of the
site.
In
terms of low-power consumption, the R&D team of Berlede has
optimized the electromagnetic drive system of the servo valve. By
adopting a high-efficiency permanent magnet coil and an intelligent
power management module, the product's rated power consumption is
reduced to less than 15 W, which is 30% lower than that of similar
products in the market. Under long-term continuous operation, this
low-power consumption advantage can significantly reduce the energy
consumption of the entire automation system, thereby lowering the
operating costs of enterprises. Meanwhile, the low-power operation also
reduces the heat generation of the product itself, avoiding the
performance degradation caused by overheating of the valve body, further
ensuring the long-term stable operation of the equipment.
The
extensive application of the Berlede 50 L/min low-flow servo valve
covers multiple high-precision industrial fields, and it has achieved
remarkable application results in various scenarios. In the field of
precision machine tools, for example, it is used in the feed system of
high-speed machining centers, accurately controlling the flow of
hydraulic oil or cutting fluid, ensuring that the tool feed speed is
stable and precise, and the machining accuracy of workpieces is improved
by more than 20%. In the field of robotics, it is applied to the joint
drive system of collaborative robots, providing precise and smooth power
output for the flexible movement of the robot joints, enabling the
robot to complete complex operations such as precise grasping and
assembly.
In
the medical equipment field, it plays a crucial role in minimally
invasive surgical instruments and precision infusion systems. In
minimally invasive surgical robots, it accurately controls the flow of
the driving fluid, ensuring the fine movement of the surgical
instruments and reducing the trauma to patients; in precision infusion
pumps, it precisely regulates the infusion flow rate, ensuring the
safety and effectiveness of clinical treatment. In addition, the product
is also widely used in chemical reactor temperature and pressure
control systems, laboratory precision fluid mixing equipment, and new
energy battery electrolyte filling systems, providing reliable precision
control support for the stable operation of these equipment and the
improvement of product quality.
Against
the backdrop of the accelerating process of industrial 4.0 and the
continuous advancement of intelligent manufacturing, the demand for
precision control components in the industrial field is becoming
increasingly stringent. The Berlede 50 L/min low-flow servo valve, with
its excellent comprehensive performance, is perfectly aligned with the
development trend of modern industrial automation. It not only improves
the operational efficiency and precision of equipment but also reduces
the energy consumption and maintenance costs of enterprises, creating
significant economic benefits for users.
Looking
to the future, Berlede Company will continue to invest in R&D based
on this product, integrating more advanced technologies such as
industrial Internet of Things (IIoT) and artificial intelligence. For
example, by adding an intelligent monitoring module, the product can
realize real-time remote monitoring of its operating status, predict
potential faults in advance, and realize predictive maintenance. With
the continuous expansion of application scenarios and the continuous
upgrading of product functions, the Berlede 50 L/min low-flow servo
valve will play a more important role in the field of industrial
automation, providing stronger technical support for the high-quality
development of global manufacturing industry.
