The IMI PBM FD Series flush tank steam valve delivers bubble-tight shutoff for industrial and sanitary applications. Featuring Adjust-O-Seal® technology, it allows in-line seat adjustments to extend service life. The pad radius design facilitates efficient drainage while reducing pocket areas above the ball. With upstream and downstream sealing, it supports purging, draining, and cleaning. Built from 316L stainless steel, Hastelloy®, and AL6XN™, it is vacuum-rated and available in buttweld, flange, NPT, and socket weld connections. The FD Series is ideal for biotech, pharmaceutical, and high-purity industrial applications requiring reliable, sanitary flow control.
