How to select G-Series Valves 
  1. Determine the minimum Cv needed to meet system requirements.  See Engineering Data.
  2. Select orifice size.
  3. Determine valve type, body type and end connections.
  4. Select the compatible seal material.
  5. For air operated valves specify "NC" (Normally Closed) or "NO" (Normally Open).  Indicate system and pilot (actuation) pressure.
