Q911F Electric Three-Piece Ball Valve
I. Introduction:
The electric three-piece ball valve is a type of valve where the sphere rotates 90° around an axis perpendicular to the flow path. It consists of a rotary motion electric actuator and an O-type valve. The electric three-piece ball valve is a high-performance regulating or on-off valve of the rotary type. It accepts input and output current signals or voltage signals from industrial automation control (DCS, PLC system) instruments, and can realize proportional regulation or two-position on-off control of fluid media in process pipelines, thereby achieving automated control of parameters such as flow, pressure, temperature, and liquid level of the fluid medium. The electric three-piece ball valve (internal thread connection ball valve) and butt weld connection ball valve are suitable for various pipelines with PN 1.0～4.0 MPa, operating temperature of -29～180℃ (sealing ring is reinforced PTFE) or -29～300℃ (sealing ring is polyphenylene sulfide), used to cut off or connect the medium in the pipeline. By selecting different materials, it can be respectively suitable for various media such as water, steam, oil, nitric acid, acetic acid, etc.
II. Product Features:
1. The three-piece electric ball valve has small fluid resistance, which is one of the valves with the smallest fluid resistance among all valve types. Powered by AC220V, AC380V or DC24V power supply voltage, it accepts current signals (4-20mA, 0-10mA or 1-5VDC) or voltage signals to control its operation. By rotating the sphere 0~90° with the torque output from the rotary motion, it can complete the opening/closing action or regulating action.
2. The fully electronic electric actuator adopts an integrated electromechanical structure, with functions such as on-site servo operation, position feedback of opening degree signal, position indication, and manual operation. It has strong functions, reliable performance, and simple connection. By inputting current signals or voltage signals, the rotation angle of the core (any angle between 0-90°) can be changed to realize proportional regulation action.
3. The core channel is flat and smooth, not easy to deposit medium, and can perform line-type ball cleaning. It has a simple structure, light weight, and good sealing performance, and is especially suitable for occasions requiring zero leakage rate.
