For more than 25 years, the Dresser Masoneilan LincolnLog® has been the premier solution for high pressure liquid letdown applications designed for pressure drops up to 450 bar (6500 psi). The LincolnLog product line provides multi-stage pressure letdown control with excellent trash tolerance providing a reliable long-term solution for critical service applications.
The LincolnLog is an axial flow valve with large flow passages ideal for high pressure liquid letdown applications where cavitation and dirty fluids are major concerns. Some typical applications include pump recirculation, feedpump start, spray water control, water reinjection and separator letdown.
The LincolnLog is available in standard designs to meet a wide range of high pressure anti-cavitation applications in both globe and angle body options. One of the major features is the large flow areas which allow for safe passage of entrained solids through the valve without damage.
The LincolnLog is also available in various optional configurations, including soft seat design for bubble tight shut-off as well as cryogenic construction.
Benefits
The LincolnLog design combines a traditional top entry valve with a simple yet effective trim design using a minimum number of parts. Unlike other severe service valve designs, the LincolnLog valve offers single piece plug and liner components for added reliability and easy field service.
The robust construction provides reliable, trouble-free operation helping to maximize process uptime. Plus, versatile options allows end users to minimize inventory and training while the heavy guiding provides smooth operation.
The result is improved process control and higher process yields.
