STREAM SELECTION TIGHT SHUT-OFF DIAPHRAGM VALVES, DVS SERIES

 

The DVS series was specifically designed for sample stream selection systems. The DVS has no dead volume effects, provides continuous flow path and has a purge system. Any configuration whether it's On/Off, Sample By-Pass or Double Block & Bleed systems, can be pneumatically or electronically actuated.

 

 

  • Tight positive port shut-off 

  • Continuously sweeping flow path

  • Patented purge feature to prevent inboard/outboard contamination

  • Usable with liquid or gas media

 

All AFP valves have a unique, patented purge design that isolates the rotor seal from the atmosphere. The purge groove prevents contamination in the sample or carrier gas, enabling better detection sensitivity, repeatability and avoiding unnecessary maintenance or costly shutdowns. 

 

  • Purge grooves surround process and sample flow paths

  • Eliminates potential contaminants

  • Increased sample integrity and instrument sensitivity 

  • Avoid downtime
