IPEX’s vented ball valves are designed to protect the ball and body from a failure due to potential off-gassing. When a ball valve is cycled to the closed position, liquid may be trapped in the ball cavity. Chemicals such as sodium hypochlorite (NaOCl), hydrogen peroxide (H2O2), and aqua ammonia (NH3) may off-gas and cause a potentially dangerous pressure build up. Without proper pressure relief, this may cause the valve to prematurely fail.
