Key Features
-
Compact modular structure: Small volume, easy to install and maintain, can be integrated with pressure control valves and flow control valves, reducing pipeline connections and potential leakage risks, and adapting to limited installation space.
-
Precise commutation control: Stable movement, fast response speed, accurate control of hydraulic oil flow direction, which can meet the precise control requirements of executive components and reduce system energy consumption.
-
Strong environmental adaptability: Wide operating temperature and viscosity range, optional metal hard sealing design, suitable for complex working conditions such as high temperature, high pressure and harsh medium, and widely used in engineering machinery, petrochemical and water treatment fields.
