Swing Check Valves
Heavy-duty surface swing check valves for reliable one-way flow protection in industrial oil & gas and pipeline applications.
ATV SPA Surface Swing Check Valves are engineered one-way flow valves designed for robust performance in upstream and midstream applications such as platforms, FPSO systems, pipelines, LNG facilities, power and renewable installations, and pumping systems. They prevent reverse flow by automatically closing when flow direction reverses, protecting equipment and maintaining system integrity. Built with forged or cast bodies and metal-seated components, these valves support in-line maintenance, fire-safe design, and extensive customization to meet project requirements and international standards such as API 6D and API 6A.
