Hydraulic Manifold Blocks and Cartridge Valves

Custom Hydraulic Cartridge Valve Manifold Blocks

Custom hydraulic manifold blocks integrate pressure control, flow control, directional control and load-holding functions into compact OEM hydraulic systems.

Focus: Circuit integration and valve layout
Engineering boundary: Final sizing, configuration and interface require JST engineering confirmation.

Product Overview

Series capability and selection context

Custom hydraulic manifold blocks integrate pressure control, flow control, directional control and load-holding functions into compact OEM hydraulic systems.

Circuit-specific valve integration

Cartridge valves, relief valves, check valves, counterbalance valves and flow controls can be integrated into one block.

Compact hydraulic layout

Manifold design reduces hose routing, leakage points and installation space in OEM hydraulic systems.

Designed from schematic

JST reviews the hydraulic schematic, valve list, port threads and mounting envelope before machining.

Configuration Reference

Verified configuration choices

Final sizing, configuration and interface require JST engineering confirmation.

Relief valve	System pressure protection and overload safety
Check valve	One-way flow control and circuit isolation
Counterbalance valve	Load holding and controlled lowering for winches and cylinders
Flow control valve	Speed regulation and actuator synchronization
Directional valve	Actuator direction control and circuit switching
Anti-cavitation valve	Motor or actuator protection during overrunning load conditions

Applications

Typical applications

Hydraulic winch load holding and smooth lowering circuits
Wheel drive, slewing drive and travel drive control systems

Industrial presses, test benches and machine tools

Selection Guide

Information used for preliminary selection

Hydraulic circuit: provide schematic, function description or target control logic.
Pressure and flow: confirm rated pressure, peak pressure, maximum flow and oil type.
Valve functions: define relief, check, counterbalance, flow control, directional control or proportional control needs.
Port layout: specify port thread, port direction, mounting face and connection space.
Material: choose aluminum, ductile iron or steel according to pressure, weight and corrosion requirement.
Installation: confirm mounting holes, block envelope, sealing surface and service access.
Testing: define pressure test, leakage test, cleanliness and documentation requirements.
Custom valve cavity layout and oil passage design according to hydraulic schematic.
