The DN25 vacuum valve is suitable for high-purity gases such as HF etc., with a right angle structure, the valve body is made of 316L forgings and sealed with metal bellows; By using a high-precision motor transmission mechanism and a specially developed intelligent controller, precise control of the pressure and flow behind the valve can be achieved. The special design of the valve core enables equal percentage adjustment of flow characteristics.
