Ventilation Valve, TA-2 / TA-5 / TA-5F Series

Ventilation Valve, TA-2 / TA-5 / TA-5F Series

· Includes a rapid air discharge mechanism so during initial water flow, air inside the pipe is rapidly discharged, simplifying water passage.
· Operates at a wide range of pressures compared to conventional air purge valves, from low to high pressures.
· In the event of damage to the float valve body or valve seat surface after prolonged use, parts can be replaced from outside, simplifying maintenance and inspections.
· TA-5 5F includes a main body made of bronze so production of rusty water is not a concern.
· Negative pressure in the piping or tank automatically produces rapid suction of air, protecting against damage to piping due to vacuum.
