Question

Is Gas flow rate or Volumertric flow rate right one to use for thick wall?

Answer 1

Flow controllers provide a stable flow rate under varying pressure. VICI flow controllers are precision machined from aluminum or stainless bar stock to eliminate the contamination often found in die-cast parts. Positive flow shut-off is provided by an integral Viton®-sealed adjustment valve.

All our flow controllers are precision-machined from aluminum or stainless steel bar stock, eliminating the possibility of contamination or porosity often introduced in die-cast processes. Standard materials of construction are aluminum body, brass operators, and Viton seals and diaphragm. A stainless steel body is available for use in ultrapure or corrosive systems, and either body may be ordered with a stainless steel diaphragm.

NOTE: With all our flow controllers, the inlet pressure must exceed the outlet pressure by 10 psi.
