Bellow Seal Globe Valves
Bellow seal globe valves add a welded metal bellows around the stem so the primary stem seal is a metallic barrier rather than packed gland alone — the usual answer where fugitive emissions or hazardous media rule out leakage paths. The range covers a carbon-steel execution at DN15 to DN400, PN16 to PN40, flanged or buttweld ending, with WCB body, bonnet and gland flange, an A105-plus-13Cr disc and seat ring on an F6a stem, stainless-graphite gasket and graphite backup packing, operated by handwheel or electric/pneumatic actuator. Design follows DIN 3356 with DIN 3202 face-to-face, DIN 2543 flanges and DIN 3230 testing. Selection turns on bellows cycle life against operating frequency, PN class, and actuation choice.
