Product Overview
Our hydraulic manifold blocks (also known as valve blocks or integrated control blocks) are precision-machined components designed to consolidate complex hydraulic circuits into a single, compact unit. By integrating directional, pressure, and flow control valves into one solid block, we help you eliminate excessive piping, reduce leakage points, and significantly improve system response time.
As a specialized hydraulic valve block manufacturer, we support full customization—from single-piece prototypes to mass production—based on your specific circuit diagrams or 3D models.
Feature
New TLFA has the following characters
Innovative design in the TLFA series control covers is implemented. Screw-in cartridge valve is widely used in the embedded pilot control element, which makes the structure of control cover more reasonable, the use and maintenance more convenient. Available in various configurations.
You can choose cover plate of the universal plate connected solenoid directional valve and modular valve according to IS04401-03/05, or cover plate with screw in cartridge valve.
Generally, the control cover is chemically nickel- plated on the surface, so it has high corrosion resistance.
