Installation • General remarks :Forsafetyreasons,theinstallationmusttakeplaceunder the supervision of authorisedpeople takingaccountoflocalsafetyinstructionsandadvice.Thehandlingofbutterflyvalvesandtheircontrolsmust be done by staff trained in all technicalaspectsoftheiroperation.Before installation the pipes must be depressu-risedandpurged (emptyof its fluid) inorder toavoidanydangertotheoperator.Thepipeworkmustbecorrectlyalignedso thatnoextrastressisexertedonthevalvecasing.
Check the compatibility of the connection flangesagainsttheoperatingpressure:thePNnumberoftheflangesmustbegreaterorequaltotheope-ratingpressure.Thevalveisamachinedpieceofequipmentandmustnotbeusedtopriseaparttheflanges.
A mounting instruction specifying the installationcharacteristics and the commission of the Sylax25-100 mm is available on our web site www.socla.com oronrequestbyoursalesdepartment.
• Installation conditions :It is recommended that thedistancesmentionedbelow be respected in order to prolong the lifetimeofthevalve.
Mounting the valve close to pipework junctionsplaces it in turbulent zones which increase itswear.
