TRIPLE FUNCTION AIR VALVE VAIU-VB
ANGODOS VAIU-VB
ANGODOS VAIU-VB is an innovative full bore and triple function + vacuum breaker air valve.
ANGODOS VAIU-VB is an innovative full bore and triple function + vacuum breaker air valve. Made with a single chamber body, it discharges air during pipeline filling, evacuate air pockets during working condition, and the vacuum breaker system allows the adduction of large volumes of air during draining or pipeline bursts at preset differential pressure values. The design allows a smooth passage for air flow, maximizing the air flow rate, due to aerodynamic inner lines and full bore. The innovative venting system allows an automatic air release during working condition, maximizing the piping system capacity. Optionally anti-slam system or inflow system can be fitted to the valve.
PRODUCT FEATURES.
