DBW10: Com diâmetro nominal de 10mm, it is suitable for occasions where the flow demand is small and remote control of pressure unloading or multi-stage pressure control is required, such as the small hydraulic fixture system in the automated production line.
DBW20: Com diâmetro nominal de 20mm, it can meet the remote control requirements for medium flow and pressure, and is commonly used in hydraulic systems of a certain scale, such as medium-sized die-casting machines and some hydraulic lifting platforms with a relatively high degree of automation.
DBW30: Com diâmetro nominal de 30mm, it can handle working conditions with large flow and high pressure, and can achieve rapid and precise pressure regulation and unloading through electromagnetic control. É adequado para grandes sistemas hidráulicos, como grandes prensas hidráulicas e equipamentos de elevação portuária.
