Electric fixed flange ball valve
Electric motorized flange ball valves use electric multi-turn actuators. Flange connections conform to national standards. The fixed ball + spring pre-tightened valve seat ensures reliable sealing. Suitable for large-diameter pipes DN50~DN1200, with temperature resistance of 29~550℃ and pressure resistance of PN10~PN40. The product conforms to standards such as GB/T 12237 and GB/T 13927, and is widely used in petrochemical, gas, and power industries. It enables remote automated control, ensuring the safe and efficient operation of fluid systems.
