Description
DEMCO DM Серия Низкого давления Gate Клапаны – 2000, 3000 & 5000 PSI WP
The DEMCO DM Серия Низкого давления Gate Клапаны offer versatile, cost-effective flow control solutions for general service conditions in the oilfield industry. Available in three pressure ratings — 2000 PSI, 3000 PSI, and 5000 PSI — and two valve sizes — 2 in. (50 mm) Полнопроходной and 2-1/2 in. (65 mm) Reduced Port — these gate valves provide reliable performance for a wide range of upstream, midstream, and downstream applications.
Unlike the high-pressure 7500 PSI DM Серия, these low-pressure models feature four end connection options: Резьбовой, Grooved, Weld, and Фланцевый (RTJ), giving maximum flexibility for different piping systems. The valves are available with multiple body configurations, material options, and coating choices to suit various service environments from standard hydrocarbon to sour gas applications.
