PQ340F-16Q double eccentric half ball valve

Overview of PQ340F-10/16Q double eccentric half ball valve:

The double eccentric hemispherical valve is a relatively new type of ball valve, which solves the problems of slurry, mixed-flow liquid, dust and other media in industrial production in the pipeline transportation, such as precipitation, easy fouling and blockage, and the valve is not closed tightly. It has some advantages unique to its own structure, the switch is light, the ball is separated from the shell when it is turned on, there is no contact, the starting torque is small, and the rotation is flexible. When closed, the squeezing action of the hemisphere and the valve seat can remove the dirt on the sealing surface, so that the valve can be opened and closed smoothly, with high safety factor and good sealing performance. The eccentric structure of the sealing surface enables the spherical surface to automatically compensate for wear and maintain the sealing of the valve with a long service life. There are two types of valve surface paint: normal temperature and high temperature. Imported paint with a temperature resistance of 600°C is used for high temperature. After spraying, the paint will not burn, charring, coking, and discoloration after spraying. Equipped with a multi-turn electric actuator, it can realize the adjustment and close shut-off of the medium. It is especially suitable for the steel industry, aluminum industry, paper pulp with fiber, small solid particles, coal ash, petroleum gas and other industries.

PQ340F-10 / 16Q double eccentric half ball advantages points:

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

2. Simple structure, small size and light weight.

3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics, with good sealing performance, and it has also been widely used in the vacuum system.

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

5. Convenient maintenance, simple structure of the ball valve, generally movable sealing ring, easy to disassemble and replace.

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

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