Zero Static Down Stream Purge

Zero Static Down Stream Purge

Product Description

The ZDP process fabrication is a modification of a standard Zero Static valve. An integral
valve located on the back of the valve assembly provides access to a purge port downstream
of the ZSBB weir. This purge can be utilized for a multitude of process and utility applications
including steam, CIP solution or as a gas purge. The down stream integral purge valve typically
utilizes a .5” Pure-Flo valve bonnet assembly. The integral purge valve greatly reduces contact
surfaces, hold up volume and possible deadlegs as compared to purge valves that are welded to the exterior of a standard zero static valve. The ZDP is an essential element of piping systems required to meet demanding L/D ratios suggested by the ASME BPE standard.
