Atomac PFA lined stainless steel ball valves
The Atostar AS3 ball valve takes all of the benefits and features of the AKH2A valve and places them into a 316 stainless steel body.
Primarily manufactured for the pharmaceutical and semiconductor industries, the ball valve is used in places such as areas of high environmental corrosion and final production areas. One of our past customers used this valve in a situation where there were many plant strip downs and verifications, and as such they had issues with paint chips contaminating the next batch. Using these valves alongside our PTFE lined stainless steel piping helped to completely resolve this problem.

The AS3 has many features that make it one of the best lined ball valves in the world. Stainless steel fasteners and body ensure long term protection from external corrosion. There is no need for any painting so no flakes or chips can contaminate any processes, especially useful when cleaning down components between campaigns.
When used in conjunction with our range of PTFE / PFA lined stainless steel piping systems gives a complete easily cleanable, externally corrosion resistant, aesthetically pleasing piping system.
The AS3 has Cavity filled seats ensure minimum product hold up. T slots machined in to the cast body ensure the PFA liner is secured making it suitable for operation in vacuum conditions. The floating ball offers low turning torques and low pressure positive bubble tight sealing. The seats, ball, stem and stem packing all easily replaceable on site allowing easy maintenance and overhaul.
