Explosion-proof Electric V-port Control Valve
Explosion-proof electric V-type regulating valve adopts a V-shaped valve core with strong shearing force. It features explosion-proof design suitable for hazardous chemical scenarios, high regulation accuracy and reliable sealing, making it ideal for precise control of media containing particles.

Features
- Light weight: Thanks to the integrated valve body structure, an ultra-short face-to-face dimension is achieved, and the overall weight is greatly reduced to approximately 50% of that of conventional ball valves.
- The shear edge formed between the seat and the V-type plug can easily cut off various impurities in the pipeline, effectively ensuring unobstructed flow.
- The unique V-type plug structure solves the problem of control stability inherent in traditional ball valves. For stable flow regulation, the equal-percentage characteristic ensures a linear relationship between the controlled parameter and valve opening. Flow increases gradually as the valve begins to open.
- The valve plug defines the flow characteristics of the valve. Plugs with different shaped openings allow the same nominal size valve to provide different CV values and flow characteristics.
- Double-sided spherical sealing enhances sealing performance and effectively controls leakage, achieving zero leakage with a sealing class of IV.
