Zipson’s flanged metal seated ball valve was designed according to B16.34. 207M is 2-pc flanged metal seated ball valve with ASME150/ ASME300/ PN16/ PN40 rating; 107M is 1-pc flanged metal seated ball valve with ASME150 rating; 305M is 3-pc flanged metal seated valve with ASME600/ ASME900 rating to satisfy world wide customer’s demand. With spring loaded stem, inconel spring behind the seat, our metal seated ball valve has a longer life time and better sealing ability. Metal to metal seated ball valves are suitable for high temperature steam, hot oil, hot gas or abrasive media, slurry which contain particles in petroleum, power generation, pulp & paper, mining industries.
With its own foundry and valve plant set in Taiwan, Zipson could not only provide customized products but also control the quality strictly and thoroughly.
To make sure the performance of each process in production, both foundry and valve plant have ISO/ CE PED certificates and are audited every year.
In addition, for precise quality control, Zipson is also equipped with 2 CMMs, which are laboratory-level inspection equipment.
To comply with different working condition, except various end connections (Flange/ thread/ SW/ BW), we also provide special alloy material (Dupex, Super Duplex), several hard surfaces treatment (Hard Chrome, Tungsten Carbide, Chrome Carbide by HVOF coating), different degree V-ball (15°/ 30°/ 60°/ 90°), heating jacket for steam/ hot oil/ slurry/ abrasive media. Customized service is available if above options can’t meet customer’s requirements.
207M & 305M 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.
