An pneumatic V-ball valve（V port ball valves）is a device that uses a pneumatic actuator to control valve operation, and its primary purpose is to regulate the flow of fluids, especially in applications requiring precise flow control and the ability to shut off fluid flow. Here are some details about pneumatic V-ball valves:
Chemical Industry: V-port ball valves（segment ball valve）are well-suited for applications in the chemical industry where precise fluid control and flow regulation are required, especially for handling various chemicals, solutions, and corrosive media.
Special Seat and Seal Design: V-port ball valves（segment ball valve）typically have specially designed seats and seal structures that can effectively cut and clear particles in the media. This reduces the impact of particles on the seal and lowers the risk of leakage.
Knife gate valves are challenging to achieve zero leakage in practical applications. While knife gate valves can provide good sealing performance when closed, there may be minor leaks due to contact surfaces and clearances between the blade and the seat, as well as the connection between the blade and the valve body.
Streamlined Flow Path: V-port valves feature a V-shaped design in their flow path, allowing for smooth fluid flow, reduced resistance, and lower energy consumption.
The suitability of a knife gate valve for high-temperature environments depends on the specific model, materials, design, and the requirements of the high-temperature conditions. In general, knife gate valves can be used in high-temperature environments under the following considerations:
