Product Information
Humi-Valve® TA340-R SKU: TA340-R Humi-Valve® TA340-R Categories Breather Valves , Humidity Indicating Valves , Pressure Control Description The TA340-R HUMI-VALVE ® incorporates a Humidity Indicator (not separately replaceable) and a two-way Breather Valve in the same aluminum housing, thereby saving space and the cost of an additional hole in the case. The valve has separate and distinct settings for both pressure and vacuum relief. It has a flow rate of 0.5 to 3.0 SCFM at 1.5 psid above the valve setting. Standard settings are from 0.5 psid to 3.0 psid reseal pressure. The lower the setting, the higher the flow rate, making this valve suitable for transit cases and similar applications up to 25 cubic feet in volume. Designed to accept a replaceable desiccant cartridge , this valve will mate with our Mounting Flanges for ease of desiccant replacement. Desiccant cartridges are available in lengths of up to six inches and hold approximately 6.5 grams (0.23 ounces) per inch of cartridge. There is a separate air path to the Humidity Indicator, bypassing the desiccant cartridge. IMPORTANT: The installation of the desiccant cartridge will reduce the available flow rate for a given pressure setting. The TA340-R Breather Valve is lightweight, rugged, tamper-proof and requires no field maintenance. Corrosion-resistant materials are used throughout. The valve seal is made of silicone rubber. A manual release push button is standard on all TA340-R Breather Valves. It is used to equalize residual pressure or vacuum differentials in order to make opening the container easier. Gasket, washer and hex nut are provided with each valve. The standard TA340-R valve shows humidity levels of 20%RH, 40%RH, and 60%RH. This valve is also available with humidity levels of 10%RH, 20%RH, and 30%RH. Specify these lower humidity levels by substituting TA341 for TA340 in the part number. RFI/EMI shielding is available. TA340-R Valves may also be equipped with a rear-mounted High Flow Filter , which can also incorporate RFI/EMI shielding.
