TEST BENCHS for High Flow / High-Frequency Response Hydraulic Valves

We specialize in Chinese-manufactured test equipment for hydraulic components, including hydraulic proportional multi-way valve test benches, hydraulic proportional valve test benches, and hydraulic servo valve test benches.

Applications: Multi-way Proportional Servo Valves & Other Hydraulic Valves

In mobile/construction machinery (excavators, cranes), load-sensing proportional multi-way valves adjust power to real-time loads for smooth handling, while counterbalance valves prevent load slippage—ensuring safety in rugged conditions.

For industrial automation (injection molding, metalworking), servo valves deliver ultra-precise positioning for consistent quality; proportional valves fine-tune pressure/flow; and compact cartridge valves simplify circuit integration, boosting factory productivity.

In agricultural machinery (tractors, harvesters), proportional valves regulate tool speed/angle, and pre-assembled hydraulic valve blocks cut maintenance, optimizing planting/harvesting efficiency.

In heavy industry (steel mills, wind turbines), cartridge valves manage high-pressure processes, while load-sensing/counterbalance valves stabilize mining/wind equipment—supporting durable infrastructure operation.

Interchangeable / Equivalent with Premium Brands :More Affordable Alternatives

Our company has been committed to breaking through high-end hydraulic technologies, with high quality and cost-effectiveness as its business principles. Currently, its product range has mainly achieved equivalent replacement of high-end hydraulic valves, including HAWE load-sensing PSL/PSV proportional multi-way valves, MOOG servo valves, Rexroth proportional valves, HydraForce cartridge valves, and Bucher counterbalance valves.

It has achieved full localization replacement, with 20 years of mass application, and won consistent praise from domestic first-tier construction machinery brands, industrial equipment manufacturers, iron and steel metallurgy as well as thermal power enterprises.
