What are the main differences between V-type ball valves and other control valves?
It has flow characteristics close to equal percentage distribution, good sealing performance, and low flow resistance; it is commonly used for throttling control of fibrous and viscous fluids. It has a high flow capacity, twice that of control valves with the same diameter. It offers a large adjustment ratio, ranging from 200:1 to even 300:1. The operating pressure should not exceed 6 MPa
Most control valve bodies these days are of the globe valve type, with a straight stroke. The V-type ball valve rotates at an angle; it belongs to the category of fixed-ball valves and is also a single-seat sealed ball valve. Its regulation performance is the best among ball valves, and its flow characteristics are nearly equal percentage-based (if high precision in flow control is required, then control valves are certainly more suitable). The V-shaped cutout creates a shearing effect between it and the metal seat, making this type of valve particularly suitable for media containing fibers, tiny solid particles, slurries, and similar substances. Suitable for frequent use, featuring rapid opening and closing, light weight, low fluid resistance, simple structure, relatively small volume, light weight, ease of maintenance, good sealing performance, no restrictions on installation direction, arbitrary flow direction of the medium, no vibration, and low noise.
