Plug Valves

A revised look at the Plug Valve makeup. As higher-pressure demands are made, the existing conventional constructions are proving less and less suitable, with valves failing in a relatively short time, mainly due to grease washout during operation. Once the grease is lost, corrosion and leakage set in, resulting in premature failure of the valve. GARTECH have redesigned the valve to enhance the single energized conventional sealing in the flow path, with a second energized sealing arrangement, which provides further isolation between the flow and the valve cavity. The isolation is provided across the ¼ turn movement of the valve providing consistent sealing and protecting the valve cavity.
