Flow Selection Valve Selection Guide
1.
Select the number of valves / inlet ports. All Flow Selection Valves have the specified number of inlet ports PLUS a common port. For
example, a 3-port valve has a total of four ports (three inlet and one common).
2.
Select the orifice size. Orifice sizes range from Ø0.032” (0.81mm) to Ø0.125” (3.2mm).
3.
Confirm that the appropriate materials of construction are available in the specified valve series (for material combinations not shown
please contact your regional sales office).
4.
Turn to the pages indicated to see full details and ordering information for each valve.
