Liquids handling specialists PUMP ENGINEERING offer the extensive range of Badger Meter control valves which enable the precise control of liquids and gases in the most challenging applications and demanding environments. A good example of this is their range of valves available in a bellows seal design, such as their Type 808 bellows sealed globe valve. This is an ideal choice 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.
