The 3-pc metal seated ball valve 305M & 306M are the most popular metal to metal ball valve series in Zipson’s product range. When the working temperature less than 260°C, soft seats like PEEK (450G) or PEEK+Carbon (450CA30) still can handle it. Over this working temperature, metal seated valves are the proper choices.
305M & 306M heavy duty designed for the working temperature over 260’C, abrasive media which contain particles that will damage soft seats after certain operations. The petroleum, power generation, pulp & paper, mining industries are suitable to use Zipson’s metal seated valves.
305M & 306M are floating ball design valves, the pressure differential is an important parameter we’ll need to consider before we use these valves. Please check the “pressure differential table” before chose the valves.
In Zipson, metal seated valves can be with special alloy for all high temperature/ high velocity/ particles contain media or even corrosive media.
