Chevron renovated the naphthenic acid plant, part of the Pascagoula, Mississippi Refinery of Chevron U.S.A. Inc., in mid-1979. They installed plastic-lined valves in the caustic and acid water piping systems. The valves combine the excellent sealing characteristics of a plug valve with the minimal rotary contact surface and low pressure drop of a butterfly valve. The valve has a molded-in-place PTFE liner resistant to abrasives and corrosives at temperatures of 450/sup 0/F, and is rated for pressures from full vacuum to 150 psi.
