A grooved butterfly valve with a manual lever handle, mainly used for quick installation and fluid control in fire protection, water supply and drainage, and HVAC piping systems.
A manual or semi-automated actuator for valves (such as butterfly valves, gate valves, ball valves, etc.), which achieves valve opening and closing and adjustment through worm gear transmission. Its core features are labor-saving operation, high torque output, and precise control, suitable for large-diameter or high-pressure difference valves.
Worm gear double-disc butterfly valve
A double-flanged butterfly valve using worm gear transmission, suitable for pipeline systems requiring manual adjustment or partial automation control. It features a compact structure and easy operation, allowing precise flow regulation and position locking via the worm gear head.
A worm gear transmission mechanism with signal feedback device, typically used for remote operation and status monitoring of gate valves, globe valves, and other valves. It combines the mechanical transmission of the manual worm wheel head with electrical signals, providing real-time feedback on the valve's open/close position (such as fully open, fully closed, or intermediate position), facilitating integration with automated control systems.
Cast steel flange butterfly valve
A butterfly valve with a cast steel valve body and flanged connection. It features high strength, good pressure resistance, and high-temperature resistance. It is widely used in pipeline systems in various industrial fields such as petroleum, chemical, power, and metallurgy, suitable for various media including water, steam, oil, and gas.
