Springs and pressings play a critical role in hydraulic valve functionality, ensuring precise force application, pressure regulation, and long-term reliability. Our components are engineered for high-load applications and are manufactured to meet the most stringent tolerance and durability requirements.
Hydraulic valves are indispensable across many diverse industries including industrial machinery, aerospace technology, the oil and gas sector, and in heavy machinery across agriculture, mining and construction. They are part of high-pressure fluid control applications, ensuring precise regulation of hydraulic flow and pressure. These valves rely on compression springs and wave springs to maintain accurate pressure control, reliable actuation, and smooth operation under extreme conditions.
We offer custom-engineered solutions for:
Flow Control Valves
Pressure Control Valves
Directional Control Valves
Found in hydraulic power units, construction machinery, and braking systems, these valves prevent system overloads and pressure spikes, such as in an exhaust system valve. Our coil springs are designed for durability and reliability. Made from corrosion-resistant alloys, they undergo shot peening for enhanced strength, and are rigorously tested under high-cycle loads to ensure a long service life. Each spring also passes strict cleanliness inspections, arriving ready for immediate use.
Used in hydraulic actuators, injection molding machines, and material handling systems, these valves switch fluid direction for smooth and precise movement, ensuring reliable actuation and accurate force application for seamless hydraulic function.
Our precision-calibrated springs and pressings undergo strict dimensional inspections, load testing, and automated quality checks to guarantee consistent, high-level performance.
A hydraulic pump transforms mechanical energy from a motor into hydraulic energy, generating flow and pressure within the system. The energy stored in the fluid is then utilized by hydraulic motors and cylinders, converting hydraulic energy back into mechanical motion for industrial, automotive, and heavy-duty applications.
In hydraulic pumps such as reciprocating piston and plunger pumps, high-quality springs with specialized performance characteristics are essential for inlet and outlet valves. They ensure precise fluid regulation and reliable pressure control. Compression springs, disc springs, and wave springs provide consistent force and fatigue resistance, while precision pressings and shims enhance valve sealing and structural stability.
Our engineering team can support you by calculating the optimal material grade and designing tailored spring solutions, ensuring maximum durability and efficiency in demanding hydraulic environments.
A valve actuator, also referred to as an actuator valve, serves as a control gateway by regulating the opening and closing of a valve within a hydraulic system. Integrated into the valve framework, the actuator control system automates and precisely manages fluid flow, making it indispensable in modern industrial and mobile hydraulic applications.
High-precision springs play a critical role in actuator performance by delivering the force required for smooth and controlled movement. Whether in industrial automation, energy systems, or heavy machinery, custom compression springs, disc springs, and pressings ensure reliable force application and long-term durability. Through advanced material selection, rigorous quality control, and precision manufacturing, consistent actuator performance can be guaranteed even under demanding hydraulic conditions.
Certain valve, actuator, pump, and flow control applications require extra-large springs designed to withstand heavy loads. These are often referred to as heavy springs.
With extensive expertise in spring manufacturing, advanced production facilities support both hot and cold coiling CNC technologies for compression, torsion, and tension springs in large wire dimensions. A wide range of materials can be utilized, including steels, copper, and titanium alloys, as well as high-performance superalloys such as Inconel, Hastelloy, and Nimonic, which offer exceptional resistance to high temperatures and corrosion.
Ongoing investment in advanced technology and a strong focus on quality, precision, and customer requirements ensure reliable performance of heavy-duty springs used in valves, actuators, and flow control systems.
As a full-process manufacturer, we maintain strict control over every stage of production, applying CAD/CAM, 3D scanning, pre-stressing, shot peening, grinding, and powder coating to guarantee consistency and durability. Customization options include length, force, movement, damping, connectors, color, and finish, tailored to specific application needs.
Engineering expertise extends to theoretical modeling, stress analysis, and evaluation of creep and fatigue performance, ensuring that each spring delivers long service life and dependable functionality in demanding hydraulic environments.
Spring-energised sealing solutions provide leak-proof connections, stable pressure, and long-term reliability in hydraulic systems. They perform effectively across a wide range of conditions, from cryogenic to high temperatures, and in chemically aggressive or high-pressure environments, helping to prevent system failure.
Each energising spring is engineered to address specific sealing and retention requirements. Canted coil and garter springs deliver uniform radial force for high-pressure seals, while helical and meander springs offer flexibility and responsiveness under variable pressure. Continuous top rail and anti-extrusion springs enhance retention and prevent deformation, and PEEK springs provide superior chemical resistance, protecting equipment where direct contact occurs. Selecting the appropriate spring type combined with advanced materials ensures optimal performance for both static and dynamic sealing applications.
Precision forming and rigorous quality control guarantee that each spring meets performance specifications, delivering reliable, high-performance sealing tailored to application needs.
Hydraulic valves are essential components that control fluid flow within a hydraulic system. Different types of valves serve specific functions, such as regulating pressure, directing flow, or controlling the speed of actuators. Springs within the valves play a critical role, ensuring precise movement, consistent pressure, and safe operation under varying loads.
The ideal spring depends on the application requirements, including load, deflection, operating temperature, and environmental conditions. Compression springs, disc springs, wave springs, and canted coil springs are commonly used in hydraulic systems, each offering unique force, fatigue resistance, and dimensional characteristics. Consulting with an experienced spring manufacturer can help select the most suitable type for your specific application.
Key factors include material selection, surface treatment, manufacturing quality, operating temperature, and load conditions. Corrosion-resistant alloys, proper shot peening, heat treatment, and strict quality control enhance spring longevity. Design considerations, such as pre-stressing and fatigue testing, also ensure reliable performance over time.
When requesting a custom spring, provide details such as:
Load and deflection requirements
Operating environment (temperature, chemical exposure, pressure)
Dimensional constraints (inner/outer diameter, free and compressed length)
Desired material and surface finish
Expected life cycle and fatigue requirements
Material selection depends on load capacity, corrosion resistance, operating temperature, and fatigue resistance. Common options include high-quality steels, stainless steels, titanium alloys, and high-performance superalloys such as Inconel or Hastelloy. Working with an experienced spring manufacturer ensures the material meets both mechanical and environmental demands of the application.
HEGONG SPRING ® provides reliable, high-performance hydraulic springs and custom solutions for valves, actuators, pumps, and sealing systems, ensuring optimal performance and long-term durability in even the most demanding industrial applications.
