Product Information
TA798 Ultra High Flow Relief Valve SKU: TA798 TA798 Ultra High Flow Relief Valve Categories Breather Valves , Pressure Control , Ultra High Flow Relief Valves Description The TA798 high-flow vacuum relief valve is designed to offer the maximum air flow possible for a 4.5-inch diameter valve. It achieves this flow with its unique design that utilizes powerful rare earth magnets instead of the compression springs found on a conventional breather valve. The magnets allow the valve to open quickly and completely once the initial opening resistance is overcome. The TA798 can be used in any application where rapid, high volume, air intake is required. Each valve is shipped preconfigured, requires no field maintenance, and is supplied complete with a nut, washer, and gasket. Additionally, the TA798 may be configured with a manual release button, which is used to equalize vacuum differentials in order to make opening the container easier. The chart below shows the typical flow performance for the TA798 high-flow vacuum relief valve. The dashed lines show varying cracking (opening) points. As shown in the chart above, various cracking pressures are available for the TA798 valve. The reseal pressure of the valve, however, is not selectable due to the valve's high volume of air flow. In many cases, the valve will completely equalize the pressure inside an enclosure with its surrounding atmosphere before the valve closes.
