Duo-ChekValves
Installs betweenmating flangeswith 10 to 20% theweight of flanged swing
checks in popular sizes -
Savesmoney in initial valve cost andprovides
lower installation cost.
Plate heel is lifted first by design to prevent seat wear.Employs two spring-
Ioaded plateswith flat seats -
Gives superior performance andbubble-tight
shutoff with resilient seats.
Maximumdeflection of 140°, provides improved valve response and longer life-
Savesmoneywith longer valve life and improved systemperformanceby
reducingwater hammer.
Improves valve response and reduces friction forces by 66% -
Further
assurancesof non-slamperformancewith faster valve response.
Configuration simplifies valve insulation -
Savesmoney.
Provides options to suit application needs -
Eases your selectionprocessby
utilizing the industry leader as your single source.
Versatility formany services -
Satisfiesmore applicationneeds.
Providesmore rigidity than pipe, eliminating concerns of pipe bending loads of
flanged valves -
Safety against thermal or seismic catastrophes.
Some sizes suitable for horizontal or vertical up positions -
Simplifiespiping
design, eliminates constraints that swing checks create.
For critical service applications, prevents possible escape of unwantedand/or
hazardousmaterials to atmosphere -
Safety in critical services eliminates
and/or environmental concerns. Standards inLug andDoubleFlange
Designs.
In horizontal position flow allows plates to function freely and full openunder
lower flow conditions as compared to swing check -
Reducespressure loss,
improvesdynamic response and eliminatesvalve chatter.
Wide size range, pressure range and added options allow furthermarket needs
to bemet -
Relianceonworld’s largest wafer check line to supplymore
needs.
