KATA Cast steel floating ball valves are offered in 2pc split body side entry or uni-body,This kind of ball valve has a floating ball supported by two valve seats. Under the medium pressure effect, a certain displacement can be generated by the ball itself so as to be pressed onto the seat seal ring at the outlet, guaranteeing tightness at the outlet.
Design standard: ISO 17292&BS 5351&JIS 2071&GB/T 12237&API 608
Full bore/Reduce bore
Anti-blow out stem : Blow -out proof design ,the lower loading stem prevents being blown-out by the medium at the abnormal risen pressure into the cavity ,PTFE thrust washers ensure the smooth operation between the stem and body.
Anti-static design:to ensure that the valve works in the flammable and explosive working conditions.
Body Cavity Pressure relief design to ensure the reliable sealing and extend the service life .
