Gall Thomson Petal Valve - Sunflex

SpecificationSizes: 3” to 24” nominal bore.Cantilever spring mechanismThe cantilever spring mechanism is a bias andbackup system. It is not depended upon toclose the petal assembly. The springs will effectclosure should there be no product flow whenan activation occurs.Material compositionExtensive testing of materials includeschemical, mechanical and electrolytic reactionduring extreme and adverse conditions. Thematerial composition and manufacturingprocess delivers the most robust breakawaycoupling on the market.CalibrationThe unit can be pre-set to precise linearoverload and flow pressure requirements:to suit individual product and transfersystem parameters.Controlled closureVariable closure speeds provide anti-line shockshutdown to protect up-stream assets such aspumps and hoses.Where required for bi-directional transfersystems, a unit with controlled closure in bothdirections is supplied.Instantaneous closureInstantaneous closure delivers immediate shut-off.This is suitable for operations with lower loadingrates or short piping systems where damage toasset due to instantaneous closure is unlikely.MBC Petal Valve optionsActivation type Controlled closure Instantaneous closureDOUBLE SHUT-OFFLinear overload and flow pressure surge Standard StandardLinear overload Stabilised StabilisedSINGLE SHUT-OFFLinear overload and flow pressure surge Standard StandardLinear overload Stabilised StabilisedP6
