Skateboarding Valve
In view of the high temperature wear-resistant gate valve required by the market, according to the Lianda of many years of high temperature wear-resistant brake valve manufacturing experience, combined with the field use condition, the design of the high temperature wear-resistant skateboard valve, its special structure can ensure that the small medium does not enter the valve cavity, gate plate and valve seat sealing surface using special coating, the coating is not easily change under high temperature, combined with high strength, has good corrosion resistance, high temperature oxidation and high temperature wear-resistant performance. Can be applicable to alumina, magnesium oxide, silica, pulverized coal, high temperature oil slurry and other media.

Structural Characteristics
Instructions
Wide sealing surface
there is a wide sealing surface between the skateboard and the valve seat, even if part of the sealing surface is damaged, the surrounding surface can continue to play a sealing role,So the valve has a long service life.
Design of dust cover
dust cover is set in the valve core. During the process of fully opening the valve and switching, the small medium will not enter the valve chamber.
Valve seat scraper design
valve seat scraper design, the movement between the skateboard and the valve seat is shear movement, can scrape off the dirt stuck on the skateboard.
Unique spray welding process
the valve body flow channel and the valve interior use supersonic spraying (HOVF) carbide technology to improve the wear resistance of the valve.
Protected sealing surface
the valve is not washed by the medium when closed or open.
Packing loading and sealing
the packing place adopts the disc spring loading design, and the long-term sealing is more reliable.
Parallel double gate structure design
using parallel double gate structure, the spring between the two gates will not appear the valve lock phenomenon under high temperature condition.
Full diameter design
using the diversion hole diameter structure design, can realize the ball clearance pipe.
