The Hydraulic Industry
The "Weight" of the National Economy
Because hydraulic technology is mostly used in places not visible in daily life, its importance is often underestimated. In reality, just as "spring flowers bloom everywhere in the city," few industrial products can be manufactured without hydraulic technology. The hydraulic industry has become a pillar industry of modern manufacturing. Although the hydraulic industry is relatively small compared to the entire national economy, it plays an important role in various fields of the national economy and has a significant impact. Therefore, it is not an exaggeration to metaphorically call the hydraulic industry the "weight" and "unsung hero" of the national economy, with the hydraulic valve block being one of its essential components.
Hydraulic products and technologies are applied in many industries, with the hydraulic valve block serving as a critical element in most systems. According to statistics from the China Hydraulics Pneumatics Seals Association in 2016, these applications can be roughly divided into several categories, each relying on specialized hydraulic components including the versatile hydraulic valve block.
Distribution of Hydraulic Product Applications by Industry
The chart illustrates the wide distribution of hydraulic technology across various industries. Construction machinery represents the largest segment, highlighting the critical role of hydraulic systems in heavy equipment, where the hydraulic valve block ensures efficient operation.
Automotive industry applications demonstrate how hydraulic technology enhances vehicle performance and safety, with specialized hydraulic valve block designs tailored to automotive requirements.
Even in smaller segments like aerospace and marine applications, hydraulic systems - and particularly the precision-engineered hydraulic valve block - provide essential functionality that cannot be easily replaced by other technologies.
1. Applications in Fixed Equipment
Hydraulic systems used in fixed equipment, commonly referred to as "fixed hydraulics" or "industrial hydraulics" in the industry, generally have less strict requirements on volume and weight, but there are普遍较高的期望 for control precision and working durability. These systems often incorporate a sophisticated hydraulic valve block to manage fluid flow and pressure with exceptional accuracy.
The hydraulic valve block in fixed equipment applications is typically designed for maximum durability and precise control rather than compactness. This allows for more complex internal通路设计 that can handle the specific demands of each industrial application.
Manufacturing Equipment
Metal cutting machines, forging presses, metal forming equipment, foundry and metallurgical equipment all rely on hydraulic systems where the hydraulic valve block regulates pressure and flow to ensure precise operations.
Automotive Industry
Production lines and automated equipment in automotive manufacturing utilize advanced hydraulic systems with specialized hydraulic valve block configurations to handle the high-volume, precision requirements of car production.
Processing Machinery
Printing and papermaking equipment, wood processing machinery, rubber and plastic machinery, and textile machinery all depend on reliable hydraulic systems where the hydraulic valve block ensures consistent performance.
Heavy Industry
Tunnel and mining equipment, oil drilling rigs, conveying equipment, and waste treatment facilities utilize robust hydraulic systems with heavy-duty hydraulic valve block designs capable of withstanding harsh operating conditions.
Other fixed equipment applications include power units, manipulators, test benches, entertainment facilities, food and beverage machinery, packaging machinery, water conservancy projects, shipbuilding equipment, and marine machinery. In each of these applications, the hydraulic valve block plays a crucial role in system performance and reliability.
Industrial hydraulic systems with integrated hydraulic valve block technology power modern manufacturing equipment
Key Characteristics of Fixed Hydraulics

Mobile hydraulic systems featuring compact hydraulic valve block designs power construction machinery
Hydraulics used in mobile equipment, commonly referred to as "mobile hydraulics" or "walking hydraulics" in the industry, generally require lightweight and compact designs, with relatively less demanding requirements for control precision compared to fixed systems. The development of hydraulic technology, especially screw-in cartridge valves and manifold block technology, has greatly met the needs of mobile equipment for compactness, integration, and lightweight design, while reducing the cost of applying hydraulics and greatly advancing mobile hydraulics.
The hydraulic valve block has been instrumental in this advancement, allowing for more compact and efficient hydraulic systems in mobile applications. Modern hydraulic valve block designs for mobile equipment focus on minimizing size while maximizing functionality, enabling the integration of multiple hydraulic functions within a single component.
Major Mobile Equipment Categories
Construction Machinery
Cranes, loaders, bulldozers, rollers, graders, forklifts, concrete machinery, excavators, and pile drivers all depend on efficient hydraulic systems with specialized hydraulic valve block configurations optimized for each machine's specific functions.
Commercial Vehicles
Disassembly equipment, cars, trucks, fire engines, road sweepers, waste collection vehicles, multi-purpose vehicles, forestry machinery, and agricultural machinery utilize mobile hydraulic systems where the hydraulic valve block contributes to reliable operation in varying conditions.
Specialized Transportation
High-speed rail construction machinery, large beam transport vehicles, and overhead beam erection vehicles rely on precise hydraulic control, with the hydraulic valve block managing complex movement sequences and load distribution.
Military Applications
Various military vehicles and weapons systems, such as missile vehicles, troop carriers, armored vehicles, and support machinery, employ rugged hydraulic systems with reinforced hydraulic valve block components designed for extreme environments.
According to a 2009 report by Germany's Linde Group, the output value of mobile hydraulics has accounted for two-thirds of the total output value of the entire hydraulic industry in Europe, and even three-quarters of the total output value of the global hydraulic industry. This growth has been significantly enabled by advancements in hydraulic valve block technology that have made mobile hydraulic systems more efficient, reliable, and cost-effective.
These classifications cannot be absolute. For example, although ships are mobile, because ships, especially large ships, have ample space, the hydraulic systems used generally allow for larger and heavier components, including more robust hydraulic valve block designs. On the other hand, although wind turbines are fixed, because their hydraulic systems must be installed in very narrow spaces at the top of tall towers, they require small and lightweight components, with compact hydraulic valve block solutions being essential.
3. Aerospace and Other Special Applications
Aerospace Applications
Hydraulic components and systems used in the aerospace field must not only be small and lightweight but also have extremely high reliability, though they can accept higher prices. The hydraulic valve block used in aerospace applications represents the pinnacle of engineering, with each component meticulously designed and manufactured to meet stringent safety and performance standards.
In aircraft, hydraulic systems power critical functions including landing gear operation, flight control surfaces, and thrust reversers. The hydraulic valve block in these systems must operate flawlessly under extreme conditions, including wide temperature variations, high vibration, and varying pressure environments.
