Control ball valve

The Control Ball Valve (also known as Ball Control Valve) is a high-performance automated flow control valve that integrates the large-flow advantage of ball valves with precise regulation capabilities. Compliant with international standards (ANSI/ASME, ISO, IEC, GB), it features a quarter-turn spherical closure, automated actuator, and smart positioner—designed to receive electrical/pneumatic signals (4-20mA, HART, Profibus) for stepless adjustment of fluid flow rate, pressure, or temperature. Ideal for large-flow, high-pressure, and large-diameter systems, it balances efficiency, durability, and automation compatibility, making it a core component in industrial control systems across industries.

Universal butterfly valve

The Universal Butterfly Valve is a versatile, multi-purpose industrial valve designed for on-off control and basic flow regulation across diverse applications. Compliant with international standards (ANSI/ASME, ISO, GB, DIN), it features a quarter-turn (90° rotation) butterfly disc, rugged valve body, and flexible configuration options—making it a cost-effective, space-saving solution for low-to-medium pressure/temperature systems. Its “universal” design adapts to a wide range of media, connection types, and actuation methods, making it one of the most widely used valves in industrial and municipal sectors.

Control globe valve

The Control Globe Valve (also known as Globe Control Valve) is a high-precision automated flow control valve, combining the reliable sealing of traditional globe valves with advanced automation technology. Compliant with international standards (ANSI/ASME, ISO, IEC, GB), it features a linear-motion valve stem, precision-machined valve trim (plug and seat), and automated actuator—designed to receive electrical/pneumatic signals (4-20mA, HART) for stepless regulation of fluid parameters (flow rate, pressure, temperature). Ideal for small-to-medium flow, high-pressure, and high-precision control scenarios, it is a core component in industrial automation systems across industries.
