ITT Body Valves 2-Way

Pure-Flo Solutions Group has developed a line of 2-way valve bodies that help address the needs of the Bioprocessing and Pharmaceutical industries for high quality, welded process systems.  Providing diaphragm valve bodies with controlled sulfur 316L stainless steel material and weld tangents long enough to accept the most common orbital weld head in the industry.  This has allowed them to eliminate two of the most common concerns in valve-to-tube welding known today.
The Pure-Flo line of sanitary diaphragm valve bodies fully complies with the controlled sulfur requirements for chemical composition of 316L set forth by the ASME Bioprocessing Equipment Standard 2002.  Increasing the valve weld end tangent lengths of the valves required for ASME BPE fittings ITT made the diaphragm valve body compatible with virtually any orbital weld head utilized in the industry.

ITT 2-Way Diaphragm Valve Body Benefits
-No welded tube extensions required for most welding equipment
-Less over-all valve body length compared to welded tube extensions
-Fewer welds in the process system
-Less validation paperwork due to fewer material certifications
-Higher quality field welds
-No narrow or off-set weld heads required

Drain marks are provided as standard on cast and forged bodies to facilitate installation and optimize drainability.  One mark must be located in the vertical plane, cutting the center-line of the pipe.  The slope of process piping must be designed to provide proper pitch in order to optimize drainablility.  Drainability in a process system is ultimately the responsibility of the system designer end user.

Pure-Flo Solutions Group customers have a choice of valve body types based on the needs and requirements of the process application.  All valve bodies are full material heat traceable to EN 10204 3. 1B. Certified Mill Test Reports are provided as standard.

Pure-Flo diaphragm valve bodies are available in a complete range of mechanically polished and electropolished internal surface finishes to satisfy system design requirements.  They are also available in a complete range of ASME BPE compliant internal surface finishes.  A complete range is provided of both internal and external electropolish surface finishing creates a superior surface finish for biopharmaceutical applications.  This improves corrosion resistance, removes inclusions and contaminants, and improves the over-all surface for cleaning and sterilization.
