A bellows seal valve for challenging applications

08 August 2015

Pump Engineering is stocking 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 is the bellows seal design, such as Badger's Type 808 bellows sealed globe valve. This is suitable for critical, zero-fugitive emission, high-purity or high-vacuum applications.

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 ¼in, ½in, ¾in and 1in and standard features include interchangeable trim sets, bellows packing, PTFE CV ring back-up packing and PTFE bellows gasket.

A range of accessories is available, including positioners, filter regulators, gauges, I/P limit switches and solenoid valves.
