bellow sealed valves - Federal International (2000) Ltd

BELLOW SEALED VALVES
The range consists of very low emission glanded valves and zero
emission bellow sealed valve. The products include gate and globe
valves all conforming to ANSI B16.34, and AP1602, BS 5352.
ZERO FUGITIVE EMISSION
Every single bellow bonnet assembly is tested for zero leakage using
helium gas and a mass spectrometer, to MSS-SP-117 Standard
requirement.
Individual sensitive leak testing ensures problems are found in the
factory - not the end users plant.
BELLOWS VALVE LIFETIME DEPENDS ON
• Leak Tested Bellow Sub-assembly
• Well pioneered bellow design and production procedures.
• Compatibility with fluid, ie. careful selection of bellows material
• Hardfaced valve sealing faces and welded in seats
APPLICATION OF BELLOWS VALVE
• Vacuum • Condensate Lines and Drains • Instrument Lines
• Hydrogen • Anhydrous Chlorine • Potassium
• Hydrogen Sulfide • Ammonia • Phosphate
• Sulfuric Acid • CO and C02 • Liquid Sodium
• Hot oil Transfer • Toxic Gases • Nitric Acid
• Radioactivity of Fluids
SAFETY OF PLANT, PERSONNEL AND ENVIRONMENT
• Any leak to atmosphere is a hazard and causes a reduction of plant efficiency. Where toxic, inflammable,
explosive or corrosive fluids are handled. Bellows Sealed Valves have an essential role to play in removing
the risk to personnel and the environment.
• Satisfaction of clean air control, whether it is the standard of EPA's proposed 100 ppm limit to air pollutants
of Gemany's standard T.A.LUFT, the bellows seal totally contains in the service media.
• Savings in energy and operational cost in steam service industries. Steam is very difficult to contain and the
cost of steam energy is very high, Bellows Sealed Valves provide the ultimate containment and isolation of
fluids saving the costs associated with lost steam and the repair of conventional valves.
