A swing check valve should be installed in a horizontal pipeline with the hinge pin positioned at the top for optimal performance.  This orientation allows gravity to assist in closing the valve when flow reverses, prevents backflow, and reduces the risk of water hammer.  It ensures the valve operates smoothly and effectively seals when needed. […]

A single block and bleed (SBB) valve uses one block valve plus one bleed valve for isolation and pressure relief in one direction. A double block and bleed (DBB) valve uses two block valves plus one bleed valve for dual isolation from both directions, providing the dual seating required by API 6D in high-hazard applications. […]
