What is a bellows sealed valve?<\/p>\n

A\u00a0Bellow Sealed Valve<\/b>\u00a0is a industrial process\u00a0valve<\/b>\u00a0designed to eliminate\u00a0valve<\/b>\u00a0leakage and are also known as ‘Zero Leak\u00a0Valve<\/b>‘ or ‘Emission Free\u00a0Valve<\/b>. … A\u00a0bellow<\/b>\u00a0is a long accordion-like tube. As the\u00a0valve<\/b>\u00a0stem strokes, the\u00a0bellow<\/b>\u00a0expands or compresses with the stroke movement..<\/span><\/p>\n

 <\/p>\n

Why bellow seal valves are used?<\/p>\n

The use of a\u00a0bellows seal valve<\/b><\/span>\u00a0significantly reduces external leakage. By covering the circumference of the\u00a0valve<\/b>\u00a0stem with\u00a0bellows<\/b>, leakage from the gland<\/span> components is reduced.<\/p>\n

 <\/p>\n

How Do Bellows Seal Valves Work<\/b>? <\/span><\/p>\n

These\u00a0valves<\/b>\u00a0feature an accordion like\u00a0bellows<\/b>\u2014i.e., the\u00a0bellows<\/b>\u00a0cartridge component, welded to the\u00a0valve<\/b>\u00a0stem and bonnet. During the\u00a0valve<\/b>\u00a0stroke the\u00a0bellows<\/b>\u00a0compress or expand along with the sliding stem’s linear motion with little to no friction.<\/span><\/p>\n\n\n\n\n\n\n\n
