Modular: The Model 5200 pipe-away conservation vent is part of the Valve Concepts, Inc. modular vent product line.

The Model 5200 can easily be converted to a vacuum only vent or end-of-line pressure / vacuum vent and can either

be direct activating or pilot operated. Maintains Accurate Settings. The Pilot Operated Model 5200 provides bubble tight (no leakage) up to 95% of set pressure or 0.5″ WC, whichever is greater and less than 1 SCFH at 90% of setting on the vacuum side of the vent. A certified test certificate is included with each vent verifying the accuracy of both the pressure and vacuum

setting and leakage. Condensate Drainage. Self-draining housing body and drip rings keep condensate away from seating surfaces, preventing freezing, binding and clogging. Air-Cushioned Seating. Air-cushion seating provides tight sealing to reduce evaporation losses. The pallets have outer guiding and center stabilizing stem to provide self alignment and tight seating.


The Model 5200 has a pilot operated pressure side which permits tank operating pressures closer to the maximum allowable operating pressure. This provides a more

positive control over vapor generation inherent in fluids with higher vapor pressures. The vacuum side of the vent is weight loaded and allows intake of air when necessaryto remain within the vacuum design rating of the tank.
