The GGG40.3 Control Valve is constructed from GGG-40.3, a ductile iron material featuring nodular graphite, ensuring high toughness and reliable performance even at low temperatures with a guaranteed notch impact energy at -20 °C. Designed to regulate fluid flow, this control valve adjusts the size of the flow passage in response to signals from a controller, providing precise control over flow rate and subsequently managing critical process quantities.
