With AAK variable pilot ratio hydraulic counterbalance valve, Milan's equipment energy consumption i

Milan from the Netherlands is an old customer of AAK. He purchased many non-standard customized hydraulic counterbalance valves from AAK. In March this year, Milan asked by email: can AAK design hydraulic counterbalance valves to reduce the energy consumption of equipment? It was learned that a hydraulic elevator developed by their company focused on the selling point of "low energy consumption and high efficiency", but after equipment commissioning, the energy consumption was not as good as expected and could not be promoted to the market.

How do AAK engineers design variable pilot ratio hydraulic counterbalance valves? The variable pilot ratio hydraulic counterbalance valve is an innovation from the mechanical structure of the valve, which utilizes the characteristics of variable pilot ratio and pilot pressure. When stable, a low pilot ratio is used, and when unstable, a high pilot ratio is executed.
