This is a High-Pressure Manual Butterfly Valve, a manual shut-off valve designed for high-pressure working conditions. It mainly consists of a high-rigidity butterfly valve body, metal-sealed butterfly plate, and manual drive mechanism (handwheel):
Working Principle: Rotating the handwheel drives the valve stem, controlling the opening/closing angle of the butterfly plate (0°-90°) to realize on-off control of pipeline fluid; the metal sealing structure ensures sealing performance under high pressure.
Application Scenarios: Made of high-pressure resistant material, it is suitable for high-pressure pipeline systems in petrochemical, natural gas, coal chemical industries. It is applicable to working conditions requiring manual quick opening/closing, combining operational convenience with high-pressure sealing performance.
