Large caliber water meter control ball valve

DN32-40
Product Introduction: Fixed ball metal hard sealed electric ball valve with explosion-proof actuator, ball seat metal to metal seal, suitable for high temperature, high pressure, containing trace particles, flammable and explosive media, commonly used in harsh working conditions such as natural gas pipelines, high temperature thermal oil, coal powder, and high temperature process gases.✅  Core parameters• Model: Q947H-25C• Diameter: DN50 to DN300• Nominal pressure: PN25 (2.5MPa)Valve body: WCB cast steel; Core: welded with Stellite hard alloy• Sealing: Metal hard seal• actuator: explosion-proof type, explosion-proof grade Exd Ⅱ BT4• Power supply: AC220V/AC380V; Switch/adjustment optional• Protection level: IP67• Working temperature: -40 ℃~450 ℃• Connection: RF flange• Media: natural gas, high-temperature steam, thermal oil, media containing dust particles, flammable process fluids✅  Advantages1. Metal hard seal, high temperature resistance, erosion resistance, wear resistance, suitable for media containing particles2. Fixed ball structure, stable torque under high pressure, strong resistance to pressure difference3. Explosion proof certification, can be directly used in explosion-proof workshops and gas hazardous areas4. Sealed and heat-resistant, far superior to PTFE soft seals, suitable for high-temperature process pipelines5. Long service life, the sealing surface can be ground and repaired, and the maintenance cycle is long❌  shortcoming1. Metal hard seals cannot achieve zero leakage, and there are trace leaks (in accordance with hard seal standards)2. The highest purchase price and cost far exceed that of soft sealed ball valves3. High opening and closing torque, large actuator volume, and high power consumption4. There are still requirements for the cleanliness of the medium, and large particles of hard objects are prone to damage the sealing surface5. The sealing performance decreases under low temperature conditions, and soft seal valves are preferred for low temperature conditions
