Rail ball valve is a new type of practical product, which is a high-tech ball valve with a 90 degree swing to cut off the rotating ball core. Rail ball valve products are very suitable for safe and reliable operation under flammable, explosive, volatile, highly toxic and other environmental conditions. Widely used in chemical, petroleum, light industry, medicine, textile, papermaking, environmental protection, military facilities, airports and other transportation pipelines to cut off or circulate media.
The structural characteristics of track ball valves: track ball valves have small volume, compact structure, convenient use and installation, and long service life. Featuring a frictionless sealing structure design, when the valve is opened, the ball first leaves the sealing surface before rotating and then rotates. The contact between the sealing surfaces has no scraping effect, extending the service life of the valve.
The friction free opening and closing of track ball valves solves the problem of sealing surface friction affecting sealing performance; Top mounted structure. Valves installed on pipelines can be directly inspected and repaired online. Can effectively reduce device shutdown; The single valve seat design eliminates the safety issue of abnormal pressure increase during valve use; Low torque design allows for easy opening and closing; The wedge-shaped sealing structure has reliable sealing performance under various working conditions; Self cleaning structure of sealing surface.
