Features:

1. Compact Structure & Flexible Installation – Small size, space-saving, and can be installed vertically or horizontally.
2. Excellent Flow Control – V-port ball valve provides an equal percentage flow characteristic and an adjustable ratio of up to 300:1, ensuring precise control over a wide range.
3. Large Flow Capacity – The streamlined design and full right-angle rotation allow for high flow volume, minimal resistance, and optimized valve sizing for cost efficiency.
4. Stable & Responsive Operation – Dual-bearing structure ensures high mechanical stability and low starting torque, enhancing sensitivity and quick response.
5. High Reliability & Safety – One-piece valve body is durable and pressure-resistant, preventing leakage and ensuring long-term reliability.
6. Superior Metal Seat Sealing – Self-compensating movable metal seat provides tight sealing, extended service life, and minimal leakage (≤10⁻⁶ × rated flow coefficient)
   Strong Shearing Capability – The V-ball valve adopts a metal hard-seal structure. During rotation, the V-shaped notch and metal seat create a strong shearing force, effectively cutting through fibers and impurities. It also has a self-cleaning function, preventing valve jamming.
