Electric wedge gate valve: functions, characteristics, and applications
Electric wedge gate valve is a linear motion valve that is matched with a Z-type multi turn actuator and comes in both switch and intelligent types. This type of valve is easy to operate and is the most common opening and closing valve, which uses the up and down operation of the gate to connect and close the fluid medium in the pipeline. It has a wide range of applications, including industries such as electricity, metallurgy, petroleum, chemical, papermaking, and sewage treatment.
The product features of electric wedge gate valves mainly include the following points:
1. The fluid resistance is small, and the sealing surface is less susceptible to erosion and erosion by the medium.
2. It is easy to open, has good sealing performance, unrestricted medium flow direction, does not disturb flow, and does not reduce pressure.
3. It has a simple shape, good manufacturing process, and a wide range of applications.
The execution standards for electric wedge gate valves include GB/T13927, JB/T 79, GB/T9113, GB/T 12224, GB/T12234, GB/T12221, HG/T20592, EN1092, and JB/T9092.
In terms of main performance specifications, electric wedge gate valves are suitable for various media and temperatures. For example, carbon steel (C-type) is suitable for water, steam, and oil products, with a suitable temperature of ≤ 425 ℃; Chromium nickel steel (P-type) is suitable for nitric acid, with a suitable temperature of ≤ 200 ℃; Chromium nickel molybdenum steel (R-type) is suitable for acetic acid, with a suitable temperature of ≤ 200 ℃; Chromium molybdenum steel (Type I) is suitable for water, steam, and oil products, with a suitable temperature of ≤ 550 ℃.
The main component materials of electric wedge gate valves include valve body/cover, gate/seat, valve stem nut, handwheel, and valve stem. The material selection of these components is mainly determined based on the working environment and medium properties of the valve to ensure the performance and lifespan of the valve.
Overall, electric wedge gate valves are efficient, reliable, and economically practical valves widely used in various industrial fields.
