The Control Butterfly Valve (also known as Butterfly Control Valve) is a high-performance automated flow control valve that integrates the compact structure of butterfly valves with precise regulation capabilities. Compliant with international standards (ANSI/ASME, ISO, IEC, GB), it features a quarter-turn butterfly disc, automated actuator, and optional positioner—designed to receive electrical/pneumatic signals (4-20mA, HART) for stepless adjustment of fluid flow rate, pressure, or temperature. Ideal for large-diameter, low-to-medium pressure systems, it balances efficiency, cost-effectiveness, and automation compatibility across industries.
