Structure and Function:
Built upon a standard ball valve, it incorporates a V-notched ball and a pneumatic actuator. The V-shaped ball enables precise linear regulation and tight shut-off, while the pneumatic actuator receives control signals (e.g., 4-20mA current) to rapidly drive the valve for opening, closing, or modulating service.

Key Features:
● Excellent regulating performance: The shearing action between the V-shaped opening and the sealing ring makes this valve particularly suitable for controlling slurry media containing fibers or solid particles.
● Tight shut-off: Typically equipped with metal-to-metal hard sealing or soft sealing structures, achieving high leakage class ratings.
● Fast response: The pneumatic actuator operates quickly, making it ideal for applications requiring frequent on-off cycling or rapid emergency shutdown.

Typical Applications:
Widely used in process pipelines across industries such as petroleum, chemical, papermaking, wastewater treatment, and power generation, serving as a critical device for shut-off or flow regulation.
