It is used in conjunction with an electrical valve positioner to achieve proportional adjustment; Used in conjunction with solenoid valves and control boxes, it can achieve two position cut-off control. The V-shaped regulating ball valve core is designed with a specially shaped V-shaped notch, which has precise flow characteristics and control functions, and is suitable for controlling media such as gas, liquid, solid particles, etc. The V-shaped regulating ball valve has high shear force and self-cleaning performance due to its seamless rotation between the valve core and seat, making it particularly suitable for automation control systems in suspensions and solid particles containing fibers or small solid particles.

Product Features of V-Type Control Ball Valve:

1. The V-type control ball valve is powered by compressed air. Through the mechanical transmission of the piston rack and gear to the valve stem, it rotates the ball 0 - 90° with the torque output in angular stroke, thus completing the opening, closing or adjustment actions. By connecting with an electric-pneumatic valve positioner and inputting a 4 - 20mA current signal, the rotation angle of the valve core (any angle between 0 - 90°) can be changed to achieve the adjustment and control of parameters such as flow rate. It features precise control, small size, light weight, small flow resistance, large flow coefficient, simple structure and good sealing performance. It is truly an efficient valve for controlling process conditions.
2. Excellent regulating characteristics: The V-type control ball valve has an inherent flow characteristic approximately equal to a percentage and an adjustable ratio of up to 300:1. Therefore, the V-type control ball valve can provide precise control within a wide range of changes.
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-type control ball valve adopts a double-bearing structure, which has high mechanical stability and small starting torque, ensuring excellent sensitivity and response speed of the valve.
5. Maximum reliability (safety): The valve body is of an integral structure, which is strong and durable. Its operation is not affected by pipeline pressure, and valve body leakage can be avoided.
6. Superior sealing performance of the metal valve seat: The V-type control ball valve uses an elastic movable metal valve seat, which has a self-compensating function, superior sealing performance and a long service life. In terms of flow direction, the leakage rate ≤ 10 - - 5 × the rated flow coefficient.
7. Superb shearing ability: When the V-type control ball valve adopts a metal hard-sealing structure, during the rotation process of the valve core and the metal valve seat of the V-type control ball valve, the V-shaped notch and the valve seat generate a strong shearing force, which can cut off impurities such as fibers and has a self-cleaning function, avoiding the occurrence of valve jamming.
8. The pneumatic actuator adopts a piston-type cylinder and a crank-arm conversion structure, which outputs a large torque and has a compact size. The actuator is designed with a fully sealed waterproof structure and has a high protection level. The cylinder body uses a mirror cylinder with oil-free lubrication, a small friction coefficient, corrosion resistance, and super durability and reliability. All transmission bearings use boundary self-lubricating bearings with oil-free lubrication to ensure that the transmission shaft is not worn.

Pneumatic Actuator of V-Type Control Ball Valve

The GT, DA, and AW type angular stroke pneumatic actuators are the driving devices for the V-type control ball valve. There are two types: piston-type double-acting and single-acting (spring return type). They have a compact double (single) piston gear and rack structure, with accurate meshing, smooth transmission, large output torque, flexible and stable operation, light weight, and long service life. (The spring of the single-acting type is pre-compressed before installation, which is easy to install and disassemble, and has good safety.)
