What are the technical requirements of API valves?

The valve requires zero-stage sealing to ensure effective cut-off of the pipeline at the downstream end, consideration of the effect of metal particles in the medium on the zero-stage sealing, as well as emergency sealing measures to be taken in the event of seal failure.

Pipeline ball valve design need to consider the fire safety, once the fire, the valve’s external and internal leakage can not exceed the API607 leakage standards.

Long-distance pipeline valves should be selected to meet the requirements of strength, sealing, service life, high temperature, high pressure, abrasion resistance, corrosion resistance, fire prevention, anti-static and other aspects.
