Double Expanding Gate Valve, API 6D, API 6A

Med Expanding Gate Valves represent a sophisticated solution designed for applications requiring a positive, bubble-tight shut-off in both upstream and downstream directions, effectively managing low to high differential pressures. The valves feature a full bore port and a unique 2-piece obturator (gate+segment) design, ensuring exceptional sealing performance.

The high robustness and double block and bleed capability of this seat design are standard features, contributing to the overall reliability and safety of the valve. The smooth, continuous bore minimizes turbulence and produces a minimal pressure drop when in the open position, comparable to a pipe segment of the same dimensions.

The seat faces, situated outside the flow stream, are safeguarded against erosive wear, enabling the passage of pigs and scrapers through the valve without causing any damage. This versatility makes Med Expanding Gate Valves suitable for a wide range of industrial applications.

Manufactured under the ISO 9001:2008 Management System and certified by CE PED and API 6D, these valves comply with international standards such as API 6D and API 6A or their equivalents, ensuring compatibility with global piping systems. The flanged ends are precision-made to international standards like ASME B16.5, BS EN 1092, and BS 4504, facilitating seamless integration into various piping configurations.

Customers can choose between a rising stem and a non-rising handwheel, depending on their operational preferences. Optional features like locking devices, stem extensions, solid or flexible wedge options, bolted or pressure-sealed bonnets, soft or metal-seated options, and direct mounting to ISO 5211, further enhance the versatility and functionality of these valves.

Med's Expanding Gate Valve portfolio includes, but is not limited to, resilient seat and metal seat variants, catering to the diverse demands of the industrial sector. The valves are also NACE MR-01-75 compliant, making them suitable for use in sour service environments.
