Valve manufacturer Premier Valves has acquired a new range of metal seated butterfly valves to complement its existing range of valves. This step comes after interest in metal seat butterfly valves rose in various water industries, and because Premier Valves has entered other markets such as the mining and petrochemicals industries, where butterfly valves have been popular for many years.
The Titan triple-eccentric metal seated butterfly valve has all the approvals necessary to be used in the mining and petroleum industries.
The company has had some involvement with triple-eccentric metal seated butterfly valves and manufactured a range under license for a few years, but because of the popularity of its range of Boving and other butterfly valves, the need did not exist to pursue this range of valves.
Available in sizes up to 2 000 mm and pressure ratings up to 150 bar and temperatures up to 7 000 ºC, the Titan can be used to replace many traditional valves such as gate valves, globe valves and ball valves, performing the functions with longer life expectancy.
Because of the special machining required to achieve the right angles and tolerances on the seats of a triple-eccentric butterfly valve, general importers of the valve have to send the valve back to the factory for repair. Because of its extensive in-house capability and cooperation agreements with other facilities in South Africa, Premier offers a comprehensive repair and back-up service with a fast turn-around time for repair of these valves during plant shutdowns. Even though the life expectancy of the Titan butterfly valve is longer than traditional valves, full back-up is available when required.
The triple eccentric metal seated butterfly valve has been used extensively in high pressure mine applications such as being used as a pump control valve on 100-bar dewatering pumps. Whereas traditional valves last for a few years in this application, these valves have a life span of over 10 years service before reconditioning is required. With the benefits of compactness, ease of operation and bubble tight shut-off, the Titan Butterfly valve is set to become a competitive product in the South African valve industry.
