Custom Manifold Blocks
Compact integrated hydraulic valve assemblies - precision CNC machined in-house for leak-free fluid routing.
Solid carbon steel, stainless steel, and high-tensile aluminum manifold blocks engineered to eliminate up to 60% of external hydraulic tubing, fittings, and potential leak points. Designed in 3D CAD/CAM, machined on high-precision 5-axis CNC machining centers, and 100% pressure-tested for internal cross-port integrity under severe operating pressures.
Solid Steel / Aluminum · Up to 500 barMonolithic design for maximum structural strength and zero external pipe leakage.
By housing directional control valves, cartridge relief valves, check valves, and pressure test points inside a single precision-machined block, AB Hydromatics custom manifolds reduce installation footprint, streamline field maintenance, and withstand massive hydraulic shock pulses without loosening.
Each block undergoes deburring, ultrasonic cavity flushing, and hydrostatic proof-pressure testing to ensure zero internal cross-port leakage or contamination.

Why industrial plants choose AB Hydromatics manifold blocks
Zero External Leaks
Eliminating intermediate tubing and threaded connectors removes over 60% of potential leakage points.
5-Axis CNC Boring
Machined on high-rigidity CNC machining centers for exact port alignment, depth control, and valve cavity concentricity.
Ultrasonic Cavity Cleaning
Multi-stage chemical and ultrasonic flushing guarantees total removal of internal machining swarf and metal particles.
Electroless Nickel Plating
Uniform internal and external nickel coating protects blocks against corrosive fluids, sea air, and harsh plant washdowns.
