Electric Insulated Ball Valve Product Overview
Our company's BQ941 electric insulated ball valve is composed of a high-precision electric actuator and a straight-through jacketed insulated ball valve. It features excellent thermal and cold insulation properties, and the valve's diameter matches the pipeline diameter, effectively reducing heat loss of the medium in the pipeline. The electric actuator adopts an integrated structure with a built-in servo system, eliminating the need for an external servo amplifier. It can be controlled by inputting a 4-20mA control signal, 1-5VDC, or 220VAC power supply. The jacketed electric ball valve is mainly used in petroleum, chemical, metallurgical, pharmaceutical, food, and other systems to transport high-viscosity media that solidify at room temperature. Due to its integrated structure, the jacketed electric ball valve is more compact, lighter in weight, and leak-free with excellent sealing performance. The jacket, made of carbon steel pipe welding, is more pressure-resistant and durable compared to cast ones.
