BELLOWS GATE VALVE

The Bellows Gate Valve incorporates a metal bellows welded to both the bonnet and the stem, providing a hermetic seal around the stem without relying solely on conventional packing. As the stem moves linearly, the bellows convolutions compress or expand accordingly. Two sealing configurations are available: internal sealing, where the fluid is contained inside the bellow, and external sealing, where the fluid occupies the annular region between the bonnet and the bellow.

Available from 2" to 48" in Class 150–900 with RF, RTJ, and BW end connections, the valve offers double sealing design with enhanced corrosion and friction resistance. A sleeve-nut mechanism at the yoke converts handwheel rotary motion to proper linear stem movement. Certified to CE/PED, ISO, ATEX, SIL, and NACE MR0175.
