Product Information
TA796 Ultra High Flow Relief Valve SKU: TA796 TA796 Ultra High Flow Relief Valve Categories Breather Valves , Pressure Control , Ultra High Flow Relief Valves Description The TA796 high-flow pressure relief valve is designed to offer the maximum air flow possible for a 4-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. This valve is commonly used for rapid decompression or explosive decompression events, where it is necessary to vent a container or enclosure quickly to prevent dangerous pressure buildups. These events are typically due to a sudden loss of pressure inside an airplane fuselage, but the TA796 can be used in any application where rapid air venting is required. The TA796 valve is hardier than most other products that are meant to provide protection during decompression events. For example, a blow-out membrane can be damaged by impact from material handling equipment such as a forklift, by accidental contact with protuberances on other containers, or by incidental pressure events. Additionally, blow-out membranes are not reusable. By contrast, the sturdy aluminum construction of the TA796 stands up to rough handling, and the valve will reseal automatically after relieving excess pressure spikes providing virtually unlimited reuse. Download Magnet Valve White Paper The chart below shows the typical flow performance for the TA796 valve. The dashed lines show varying cracking (opening) points. The dotted line shows the performance of a spring-actuated valve of the same size, for comparison purposes. As shown in the chart above, various cracking pressures are available for the TA796 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.
