Hydraulic two-way valve is a commonly used Hydraulic Power Unit, with the following characteristics: 1. Simple structure: hydraulic two-way valve is usually composed of body, spool and spring, etc., simple structure, easy to install and maintain. 2. Flexible control: The hydraulic two-way valve can realize the functions of flow control, pressure control and direction control in the hydraulic system, and the working state of the hydraulic system can be flexibly controlled by adjusting the position of the spool or the pressure of the spring. 3. High reliability: hydraulic two-way valve adopts hydraulic principle to control the flow of fluid, has the characteristics of good stability, fast response speed and high reliability, and can work normally under high pressure, high temperature and harsh working environment. 4. Energy saving and high efficiency: the hydraulic two-way valve can accurately control the flow and pressure of the fl…
