Classification and Characteristics of DN15V Ball Valve V-shaped valve is a common type of valve that is widely used in various working conditions. Compared with traditional flange ball valves, V-shaped clamp ball valves have some unique characteristics. Firstly, the connection size of V-shaped clamp ball valves is thinner, which is more space saving compared to flange ball valves. Secondly, there are differences in the connection methods between the two. The V-shaped ball valve has the following characteristics: suitable for frequent operation, fast opening and closing speed, lightweight, low fluid resistance, simple structure, relatively small volume, easy maintenance, good sealing performance, not limited by installation direction, adjustable medium flow direction, no vibration and noise. The manual small caliber fixed precise adjustment dn15V ball valve produced by Yaosheng Company adopts a V-shaped structure, with a 1/4 ball shell valve core and a V-shaped notch, which can achieve large-scale flow capacity adjustment and shear force, and can achieve tight closure. This type of ball valve is particularly suitable for handling fluids with fibrous substances. In general, pneumatic clamp type V-shaped fixed ball valves are single sealed ball valves and are not suitable for bidirectional use. The edge of the valve core of the V-shaped ball valve is V-shaped, and there is a V-shaped opening on the ball body. By rotating the sphere, the ball valve produced by Yaosheng can adjust the flow rate as needed and cut off impurities in the fluid. This type of ball valve is particularly suitable for controlling pulp, mortar, and viscous fluids. In summary, the DN15V ball valve is a compact valve with advantages such as regulating flow, preventing blockages, and efficient sealing. It is suitable for various working conditions and has good reliability and service life.
