Anti Legionella Valve

Anti-Legionella Valve

The Anti-Legionella Valve converts a standard single-connection expansion vessel into a flow through vessel. By diverting part of the system flow through the vessel, it helps maintain water movement and reduce the risk of stagnation.

The ¾” version features a rotatable tee-piece, providing greater flexibility when positioning the valve during installation. A ball valve is also included to simplify isolation and maintenance.
