Coil outlets diameters (female tapped connector)
2-way vave outlet diameters (female tapped connector)
2-way and 4 way valves outlets diameters (male tapped connector)
Be careful :
in case of the 2-way valve, connectors ar not always identical.Y
ou must use different boards.
Ex :
NCH329 - 2-pipe equipment with 2-way valve :
V20A :Female tapped coil wire 3/8" fitting and 3/8" female tapped valve
V2000
®
:
Female tapped coil wire 3/8" fitting and 1/2" male threaded valve
