Floating Ball Valve

Floating Ball Valve

Floating Ball Valve Details

Elite Flow Control’s Floating Ball Valves are precision-engineered, quarter-turn shutoff valves designed to deliver reliable, bubble-tight isolation across a wide range of industrial process applications. Manufactured to ASTM standards, these valves combine robust construction, broad material compatibility, and versatile configuration options – making them one of the most widely specified ball valve types in oil & gas, petrochemical, power generation, and general process industries.

Available in three principal body configurations – 1-Piece (1PC), 2-Piece (2PC), and 3-Piece (3PC) – the range is engineered to accommodate everything from standard general service applications through to high-pressure, high-temperature, and corrosive process environments. The 1PC body offers a compact, cost-effective solution for moderate-duty service. The 2PC split body design simplifies seat and ball maintenance without full pipeline removal. The 3PC design provides the greatest installation and maintenance flexibility, allowing complete in-line inspection and repair without disturbing the pipeline.

Offered in both Full Bore and Reduced Bore configurations, and available across pressure classes from ASME 150 through ASME 2500, these floating ball valves provide outstanding flexibility for virtually any service condition. With a size range spanning 1/2″ to 6″ (DN15 to DN150), and end connections in Raised Face (RF) and Ring Type Joint (RTJ) per ASME B16.5, the EFC-1/2BV1R1 series is equally suited to small-bore high-pressure service and general process isolation duties.

All valves are constructed from ASTM-standard materials across four material grades – Carbon Steel, Alloy Steel, Stainless Steel, and Duplex Steel – ensuring full compliance, traceability, and suitability for the most demanding service conditions, including sour gas, cryogenic, and high-temperature applications.

Key Features:

  • 1PC, 2PC & 3PC body configurations available
