These one-way Pressure and Vacuum Relief Valves are installed in pairs, with one inlet and one outlet valve being used. Together they maintain the desired pressure differentials in the container.
TA750 Series valves have a flow rate of 10.5 SCFM at a pressure of 1.5 psi above the valve setting. Standard settings range from 0.5 psid to 3.0 psid reseal pressure.
The valves are tamper-proof and require no field maintenance. Corrosion-resistant materials are used throughout. The special convolute diaphragms and valve seals are made of silicone rubber. The spherical valve seats are Teflon coated for easy "break-away" action even after prolonged storage.
Manual release push buttons or twist knobs are available on the inlet valves as an optional feature. These are used to equalize pressure or vacuum differentials in order to open the container.
