Features and benefits

Robust and durable construction to ensure safety in the corresponding pressure temperature range.
Two connection methods are available: flange and butt welding.
The bonnet does not need to remove the valve from the line to enter the maintenance hinge and disc.
The valve disc closes by its own weight to prevent the fluid from flowing backwards to form a sufficiently large flow rate to avoid destructive impacts.
Minimize head loss (or aberration loss) by balancing the disc and its "airfoil" structure.
Shorter stroke, combined with the advantages of balancing the valve disc, the valve closes more quickly and minimizes the impact phenomenon.
Due to the small void on the pivot pin, a funnel-shaped tight seat seal can be achieved over the entire pressure range, ensuring the integrity of the valve seat seal between the valve disc ring and the valve body ring.
