Overview of VQ677H VQ677H-16 VQ677Y VQ677Y-16 Pneumatic wafer segment ball valve

VQ677H VQ677H-16 VQ677Y VQ677Y-16 Pneumatic wafer segment ball valve adopts cylindrical spring preloaded movable metal seat structure with compensation, with good sealing performance. The ball core and the valve seat will not be blocked or separated, and the service life is long. The V-shaped notch on the ball core has shear effect with the metal valve seat, which is suitable for controlling media with high viscosity, including fiber, solid particles, slurry and so on. The paper pulp of the structure manufacturing paper industry is excellent. The flow capacity of the valve is large, the pressure loss is small, and the medium will not be deposited in the cavity of the valve body. The valve has similar flow characteristics with equal partial ratio, large adjustable range, and the function of regulation and positioning.

Features of VQ677H VQ677H-16 VQ677Y VQ677Y-16 Pneumatic wafer segment ball valve

1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length.

2. The utility model has the advantages of simple structure, small volume and light weight.

3. Tight and reliable, the sealing surface material of ball valve is widely used plastic, with good sealing performance, and has been widely used in vacuum system.

4. It is easy to operate and open and close quickly. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control.

5. Convenient maintenance, simple structure of pneumatic ball valve, generally movable sealing ring, and convenient disassembly and replacement.

6. When fully open or fully closed, the sealing surface of the ball and valve seat is isolated from the medium. When the medium passes through, it will not cause the erosion of the valve sealing surface.

7. It has a wide range of applications, ranging from small to a few millimeters and large to a few meters. It can be applied from high vacuum to high pressure.
