Scope of application of ball valves

Edit: Vatac Vango Valves (Wenzhou) Corp      Date:Mar 20, 2015

Suitable for a wide range of ball valves, ball valves are suitable for:

1, nominal diameter from 8mm up to 1200 mm.

2, PN from vacuum to 42MPa.

3, from-204? 815 degrees Celsius operating temperature.

Particularly in the petroleum, chemical, metallurgy and other sectors, with soft sealing valves for flammable equipment and piping systems, explosive media, but you should pay attention to fire prevention and fire.

Typically, two-level regulation, strict sealing performance, mud, wear and tear, necking channel opening and closing movements quickly (one-fourth gate), high-pressure (high pressure), low noise and cavitation phenomena and gasification, a small amount can leak into the atmosphere, a small operating torque, fluid resistance of the piping system, it is recommended that valve.

Ball is also suitable for light structures, low cut (pressure difference), piping, corrosive media.

At a relatively low temperature (cryogenic) equipment and piping systems, can also be used for balls.

When adjustment is required during the execution, you need to use a special structure, ball, v-shaped openings can be customized to valve manufacturers.

In the oil, petrochemical, chemical, power, construction, working temperature above 200 c pipe systems can use the metal to metal seal ball valve.

In the metallurgical industry, oxygen pipeline systems using skimmed the ball in strict processing.

When the main line of fire in underground oil and gas pipelines, using full bore ball valves.

Ball in irrigation systems, mainly for the intake manifold of the widely used. Ball has simple structure, small size, resistance to fluid flow, the disadvantage is that when you open or close too quickly, will have a water hammer (when sudden changes in flow velocity in the pressure pipe will increase) in the pipeline. Therefore, should not be in the main valve, and no water is available, or branching tubes used for washing purposes at the end of use, washing effluent effects.
