| Design standard as per: BS1873,ASME B16.34, GB/T 12235, JB/T3595. Generally, lift is just 1/4 of the valve seat port, ensuring a short opening and closing time. Only one sealing face is designed on the valve body and valve disc, For large size valves will be designed with main disc and vice disc type, and medium flow from up disc to down disc. Full stellite overlay seat sealing surface Good for manufacturing process and easy to maintain. The valve is designed as a back seat sealing structure.
