DBW10: With a nominal diameter of 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: With a nominal diameter of 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: With a nominal diameter of 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. It is suitable for large hydraulic systems such as large hydraulic presses and port lifting equipment.
