TT7113/TT8113 Breather Valve – Pressure Vacuum Relief Valve (Spring Loaded)

The YeeValve TT7113/TT8113 series represents a line of Pressure Vacuum Relief Valves (Spring Loaded), designed as full-lift type release valves. These are tailored for applications requiring low fugitive emissions and operate around the maximum allowable working pressure of storage tanks. The full-lift design ensures a complete and stable activation at just 10% overpressure. As with all YeeValve Pressure/Vacuum Relief Valves, the full-lift relief valve functions as a precision-regulated valve with a venting rate close to zero, allowing it to reset at the preset pressure. This precision is achieved through the seamless integration of the nozzle, seat, and pallet, enabling the valve to initiate a full and stable response when the pressure or vacuum exceeds the set threshold by only 10%. This engineering finesse makes the TT7113/TT8113 series a reliable choice for maintaining optimal operational safety and efficiency.
