Double Expanding Gate Valves

OG Valves Through Conduit Double Expanding Gate Valves have a two-piece gate that, during operation, moves outward into the flow media, resulting in a double barrier in the closed position. Through Conduit Double Expanding Gate Valve design creates tight seals on both upstream and downstream seats. Friction-free design helps avoid seat and gate wear. Through Conduit Double Expanding Gate valves offer zero leakage and bi-directional tight shutoff. Double block and bleed design is standard for OG Double Expanding Gate Valves. These valves are used primarily in the Oil and Gas pipelines industry and are fully compliant with API 6D.
