| 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. |
