Description
The TA294-R Breather Valve was designed to meet the need for a low cost, two-way valve for use on transit cases and similar applications up to 8 cubic feet in volume. It is similar to TA292-R Breather Valves, except it is longer and has a flow rate of 1.0 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 reseal pressure.
The valve is tamper-proof and 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, washer and gasket. A manual release push button is standard on all TA294-R valves. It is used to equalize pressure or vacuum differentials in order to open the container.
