Fixed ball valve

Product Introduction:

Cast steel fixed ball valve series, with fireproof, anti-static design, installation without direction, wide use, reasonable price, a variety of driving methods (manual, pneumatic, electric, hydraulic, gas-liquid linkage, etc.), flexible operation.

Fixed ball valve has the following advantages:

one The fluid resistance is small, and its resistance coefficient is equal to that of the pipe segment of the same length.

2. Simple structure, small size, light weight.

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

4. Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90 degrees, easy to remote control.

5. Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.

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

Seven. Wide range of application, small diameter to a few millimeters, large to a few meters, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, the inlet and outlet should all be spherical, thus cutting off the flow.

Scope of application:

Fixed ball valve is suitable for all kinds of pipelines of Class150 ~ Class1500, PN16 ~ PN100, JIS 10K ~ JIS 20K, used to cut off or connect the medium in the pipeline, choose different materials, Can be applied to water, steam, oil, liquefied gas, natural gas, gas, nitric acid, acetic acid, oxidizing medium, urea and other media, widely used in chemical, petroleum, natural gas, metallurgy and other industries pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium.

Packing of Standard Packing: 

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 470 gallon liquid totes Special package is available on request. E FORUs’  is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.

Structural features:

1. Frictionless opening and closing. This function completely solves the problem that the traditional [wiki] valve [/wiki] is affected by the friction between the sealing surface.

2, top type structure. The valve installed on the pipeline can be directly checked and repaired online, which can effectively reduce the device parking and reduce the cost.

3, single seat design. The problem that the medium in the valve cavity is affected by abnormal pressure increase is eliminated.

4, low torque design. The stem with special structural design can be easily opened and closed with a small wheel valve.

5, wedge sealing structure. The valve is sealed by the mechanical force provided by the valve stem, and the ball wedge is pressed to the seat, so that the sealing of the valve is not affected by the change of the pressure difference of the pipeline, and the sealing performance is reliably guaranteed under various working conditions.

6. Self-cleaning structure of sealing surface. When the ball tilts away from the seat, the fluid in the pipeline passes 360° evenly along the sealing surface of the ball, which not only eliminates the local erosion of the high-speed fluid on the seat, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
