Understanding Hydraulic Manifolds: Materials, Manufacturing Processes, and Applications

A hydraulic valve block, also known as a hydraulic valve plate, mainly regulates the flow of hydraulic oil in the hydraulic system to control power transmission between the actuator and pump. Hydraulic manifolds enable effective control and distribution of hydraulic fluid in mechanical equipment.

Materials Used in Hydraulic Manifolds

Hydraulic manifolds typically use materials that are strong, durable, and compatible with hydraulic fluids. Commonly used materials include:

  • Aluminum: Aluminum alloys are lightweight, corrosion-resistant, and easy to work with. Aluminum not only serves in hydraulic circuit blocks but also in applications requiring weight savings.
  • Steel: Carbon and stainless steel offer strength, wear resistance, and the ability to withstand high pressures in industrial applications requiring high durability and reliability.
  • Brass: Brass provides excellent thermal and electrical conductivity, making it suitable for hydraulic valve blocks and specialty applications requiring these benefits.

Manufacturing Process Overview

Manufacturing hydraulic blocks involves a 10-step process, with most steps utilizing machine operations to ensure high precision and reliability:

  1. Drawing Design: Zhuoyi engineers create a preliminary design based on specifications and customer requirements.
  2. Raw Material Processing: Workers process raw materials such as aluminum or steel into billets or blanks.
  3. CNC Machining: Technicians use CNC machines for precise cutting, milling, and drilling operations.
  4. CNC Lathe Machining: CNC lathes perform turning operations to achieve specific shapes.
  5. Semi-Finished Inspection: Inspectors verify the dimensional accuracy and quality compliance of semi-finished products.
  6. Grinding Operations: Workers perform surface grinding processes to ensure smooth surfaces and dimensional accuracy.
  7. High Pressure and Ultrasonic Cleaning: Workers rigorously clean the blocks to remove contaminants.
  8. Assembly: Zhuoyi’s technicians assemble solenoids, seals, and fittings into the semi-finished blocks to create complete manifold assemblies.
  9. Pneumatic Marking: Pneumatic marking machines apply identification marks to differentiate hydraulic manifold models.
  10. Final Inspection: Inspectors thoroughly test each assembled hydraulic manifold to ensure proper operation.


Hydraulic manifolds are indispensable components in modern mechanical and industrial applications. They enable precise control and efficient fluid distribution in mechanical equipment through the integration of hydraulic valves and channels. Therefore, Zhuoyi’s careful selection of materials and meticulous production processes ensure the reliability and effectiveness of the hydraulic manifolds in various industrial environments.
