3-WAY TIGHT SHUT-OFF DIAPHRAGM VALVES, DV3/6 SERIES

 

From a simple 3-way to complex configuration with timing sequences, the DV3 or DV6 valves can be used in multiple places in your gas chromatographic systems, auto-samplers, sampling and general instrumentation. These valves have no dead volume effects, ensures continuous flow path and includes an effective purge system to prevent leak or sample contamination. The DV3 is a simple 3-way diaphragm valve while the DV6 is two 3-way diaphragm valves embedded in a compact substrate. Both of which can be pneumatically or electrically actuated.

 

 

  • Tight positive port shut-off

  • Continuously sweeping flow path

  • Patented purge feature to prevent inbound/outbound 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
