Wedge gate valves are divided into rising stem gate valves and non-rising stem gate, wedge gate valve and wedge gate valve. The open-close part of wedge gate valve is disc, so it can only be fully open and close and can’t be used to adjust and throttle. Wedge gate valve, which are widely used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial fields, especially in the power plant ash play a huge role in coal preparation equipment.
