The VAG KSSplus Howell-Bunger® Discharge Valve is a precision-engineered, end-of-line control valve designed for high-performance water discharge applications. It provides a free-flowing, cavitation-free hollow jet that dissipates energy safely and efficiently — ideal for installations such as dams, reservoirs, and hydropower systems.
