AF-35M 3-pc high performance metal  seated  ball valve with ISO  direct mounting  pad is  designed for use in high  temperature, abrasive, and  high pressure media in power  generation,  petrochemical,  mining,  and pulp  &  paper  industries.

To stand out from other economic  valves in  the market,  valve structure & wall thickness is fully comply to ASME B16.34 standard  on Class 900 construction. The  structure ensures  safety in  the  high performance  application.

Standard material for metal  seat &  ball is Co element (known as Stellite). The Co based material   is  good at hardness, corrosion resistance and stable under high temperature.

The patented  unique split seat design is perfect to seal the leakage from & over the seat  area to meet at  least Class V leakage  class.

AF-35M  metal seated ball valve is uni-directional shutoff as standard.
