Bellows sealed

For example the Type 808 bellows sealed globe valve is suitable for critical, zero-fugitive emission, high-purity or high-vacuum applications where the potential for hazardous emissions has to be eliminated.

The bellows forms a flexible static seal that is leak-free, as long as the integrity of the bellows remains intact. However, should the valve fail, a set of back-up packing allows the valve to continue to operate safely until repairs can be made.

The valve is available in sizes ¼”, ½”, ¾” and 1” and standard features include interchangeable trim sets, bellows packing, PTFE CV ring back-up packing and PTFE bellows gasket.  The trim characteristics available are; linear, equal percentage, quick-open, or double taper.

A range of accessories to enable the valve to suit specific application requirements includes positioners, filter regulators, gauges, I/P limit switches and solenoid valves.

Badger Type 808 Bellows Valves can be widely used in industrial applications including research and process plants on liquids, gases or steam.
