Valstar valves are triple eccentric, metal-seat butterfly valves for bi-directional on/off regulation. The valves are available in sizes from DN 30 up to DN 2000, and can operate over the temperature range of –200 to 1,000°C. They are sealed according to ANSI standards, with expandable and metallic gaskets (Class IV) or with lamellar gaskets (Class V and VI). Valves can be specially designed according to technical specifications. Stand 4V — Verdelet A.T.N., Neuville-les-Dieppe, France
