ROTARY VALVES, RV SERIES

 

THERE ARE 3 Types OF GC ROTARY VALVES (RV), THE G, OLP and S SERIES

 

The "G" series provides an improved rotor surface treatment which results in lower friction and less wear, resulting in longer life. Fully interchangeable with existing standard GC rotary valves, the "G" series will enable a longer life span for your instrument.

 

The "OLP" series further enhances the "G" series with the addition of a built-in protection against inbound and outbound contamination. This series is ideal when working with high sensitivity detectors, gases with low molecular weight such as helium and other challenging applications.

 

The "S" series is a sample stream selection rotary valve, with a rotor built with protection against inbound and outbound contamination. Extra grooves can isolate various selections, allowing for longer working period despite variable temperature conditions.

 

 

  • Available in 4, 6 and 10 ports

  • Internal sampling loop in 0.05µl, 0.2µl, 0.5µl 1.0µl and 2.0µl volumes

  • Purge channel surrounding each inlet port eliminating cross port leaks

 

 

 

 

 

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
