4.3 7500-MAN-MV-01 Manual Manifold
The 7500-MAN-MV-01 combines in one device a ball valve for purging and a needle valve for pressurizing
an enclosure. The ball valve has a handle for easy actuation. To provide security and prevent tampering, the
needle valve requires a slot-head screwdriver to set the enclosure pressure.
Note!
The 7500-MAN-MV-01 manifold can be used with 7500 series or 5500 series purge and pressurization
systems.
