1.Excellent flow capacity and high rigidity: When fully opened at 90°, the disc is hidden in the valve body ball chamber, ensuring a straight flow path without jamming or clogging. 2.Strong operating condition adaptability: Suitable for high-flow velocity and large-flow rate scenarios, and maintains stable operation even under small opening and high pressure differential conditions. 3.Light and flexible opening/closing: The disc disengages from the seal seat during operation with no contact, res
