Product Usage

Qv47 (Qv67) Y (F) pneumatic V-shaped regulating ball valve is an advanced control valve with a right angle rotary structure. It is used in conjunction with a valve positioner to achieve proportional adjustment; Used in conjunction with a two position five way electromagnetic and control box, it can achieve switch control. Suitable for controlling gas, liquid, and solid particulate media. Due to the seamless rotation between the valve core and valve seat, it has great shear force and self-cleaning performance, especially suitable for controlling suspensions and solid particles containing fibers or small solid particles. Therefore, this product can be widely used in the self-control systems of industrial sectors such as petroleum, chemical, papermaking, chemical fiber, power, metallurgy, pharmaceuticals, and environmental protection.

Product Structure Features:

1. The pneumatic V-shaped ball valve consists of a V-shaped valve body, a pneumatic actuator, and other accessories. It is an advanced control valve with a right angle rotary structure.
2. Excellent regulating characteristics: The V-shaped valve has an approximately equal percentage inherent flow characteristic and an adjustable ratio of up to 300:1. Therefore, V-shaped valves can provide precise control over a wide range of variations.
3. Maximum flow volume: Due to its streamlined shape and full right angle rotation control, the maximum volume is particularly high, the flow capacity is particularly large, and the flow resistance is small. Therefore, smaller and more economical valve sizes can be used.
4. The V-shaped valve adopts a dual bearing structure, with high mechanical stability and low starting torque, ensuring excellent sensitivity and sensing speed of the valve.
5. Maximum reliability (safety): The valve body is a solid and durable structure, which is not affected by pipeline pressure during operation and can prevent valve body leakage.
6. Superior sealing performance of metal valve seat: The V-shaped valve adopts a movable metal valve seat, which has self compensation function, superior sealing performance and long service life. In terms of flow direction, the leakage rate is ≤ 10-6 times the rated flow coefficient.
7. Super strong shearing ability: The V-shaped valve adopts a metal hard sealing structure. During the rotation process, the V-shaped valve core and metal valve seat generate a strong shearing force between the V-shaped notch and the valve seat, which can cut off fibers and other impurities, and has self-cleaning function to avoid valve jamming.
8. The pneumatic V-shaped ball valve has a compact structure, is small and lightweight, easy to install, and easy to maintain.
9. The pneumatic actuator adopts a piston type cylinder and a curved arm conversion structure, with a large output torque and small volume precision. The actuator adopts a fully sealed waterproof design with high protection level. The cylinder block adopts imported mirror cylinder, with oil-free lubrication, low friction coefficient, corrosion resistance, and super durability and reliability. All transmission bearings adopt boundary self-lubricating bearings without oil lubrication to ensure that the transmission shaft is not worn.
