Bellows Seal Valves

Designed specifically to contain leaks for added environmental protection and reduced waste in the workplace setting, bellows seal valves feature a unique expansion and compression configuration. When compressed, bellows seal units open to allow fluids and gases to move freely through the valve; expansion of the bellows seal closes the valve and prevents spillage and leaks from occurring. Both welded-leaf and forged bellows are used; these may be constructed of carbon steel, stainless steel, and titanium alloys and other corrosion resistant materials. Globe or gate valves are the most common types of bellows seal valves and are usually designed for pressure ratings between 150 and 2500 pounds. These valve solutions are recommended for improved containment of potentially hazardous petrochemical liquids and gases.
