Description The TA291 Breather Valve, a weather shielded version of AGM's time tested TA292-R Breather Valve, was designed to meet the need for a weather shielded, low cost, two-way valve for use on transit cases and similar applications up to 4 cubic feet in volume. The valve has separate and distinct settings for both pressure and vacuum relief. It has a flow rate of 0.5 SCFM at a pressure of 1.5 psi to 2.0 psi above the valve setting. Standard settings range from 0.5 psid to 3.0 psid r eseal pressure. The TA291 Breather Valve requires no field maintenance. Corrosion-resistant materials are used throughout. The valve seal is made of silicone rubber. Each valve comes complete with a nut and o-ring, and is intended for small cases that require a low profile valve. The conversion coated housing allows for use of a conductive o-ring for minimal RFI shielding. For higher energy RFI shielding, AGM's standard style RFI nuts are available.
