Tube Port Design
Modentic high purity ball valves use the same bore sizes for the connecting tube as well as the internal components, The dimension (I.D. and O.D.) of the end matches the tubing system diameter and wall thickness, Tube End length accommodates orbital welding tool and prevents body seal damage caused by the heat of welding. Certainly connections in clamp style in accordance with US 3A standard are available.
Although mechanical polishing is able to reduce the roughness from smeared stainless surface rapidly, there are still great possibilities of adhering particles remained, and the passivated layer will be destroyed after MP,let alone the surface could be rough easily. The performance of Electro-Polishing is able to smooth away all the defects of MP, the stainless surface is dissolved by EP to reduce roughness Ra to 0.05um. Besides, during EP process, Fe ion separates out first of all and let a passived layer be created on the stainless surface for higher resistance of corrosion.
Test & Pack in Clean Room - Class 100
Each single ball valve is carefully inspect and tested by highly trained and experienced staff. All ball valves are 100% leak tested, cleaned, and assembled in a class 100 clean room.
