Precision-Engineered Hydraulic Valves from a Trusted China Manufacturer
Sourcing reliable hydraulic valves at scale shouldn't mean compromising on quality or waiting months for delivery. Olive Branch Hydraulics is a Shijiazhuang-based hydraulic valve manufacturer with over a decade of production expertise, serving procurement teams across construction, agriculture, mining, and industrial automation sectors worldwide.
Whether you need a standard hydraulic directional control valve for fleet maintenance or a fully custom hydraulic valve OEM solution engineered to your exact specs, we deliver consistent quality, competitive unit pricing, and the flexibility to support orders from prototype runs to high-volume production.
Core Product Lines
Directional Control Valves
Our hydraulic directional control valve range covers monoblock, sectional, and modular configurations rated from 30L/min to 350L/min. Available in manual, hydraulic pilot, and solenoid-operated variants, these valves are built for demanding mobile and industrial hydraulic circuits.
Solenoid Valves
As an established hydraulic solenoid valve manufacturer, we produce DC and AC solenoid-operated valves in standard CETOP/NG sizes (NG6, NG10, NG16, NG25). Each unit undergoes 100% pressure and leakage testing before shipment. Custom coil voltages and connector types are available on request.
Pressure Relief Valves
Our hydraulic pressure relief valve supplier program includes direct-acting and pilot-operated models with adjustable pressure settings from 30 bar to 350 bar. These valves protect your systems from overpressure damage while maintaining stable circuit performance.
Flow Control Valves
For applications requiring precise speed regulation, our hydraulic flow control valve wholesale catalog includes throttle valves, flow dividers, and pressure-compensated flow controls. Available in cartridge, inline, and subplate-mounted configurations.
Custom & Specialty Valves
Need a non-standard port configuration, unique spool function, or integrated manifold block? Our engineering team works from your drawings or performance requirements to develop purpose-built solutions.
