JIS BUTTERFLY VALVE

JIS BUTTERFLY VALVE

JIS wafer type, flanged type three eccentric hard sealing butterfly valve.


Purpose and characteristic

Main configuration characteristic of 10K and 20K series of butterfly valve is composed of wafer and flange three eccentric seal, seat gasket use two

configurations of elastic seal and soft hard compatible multiple layers seal, reliable hermetic capability, so as to ensure disc can't touch sealing seat when it operation,

solve the problem of sealing seat burden unequally, prolong service life, with advantage of high temperature resistant, wearable, antisepsis etc. It has been widely

utilized in petroleum, chemical industry and industrial environmental protection water treatment, high buildingconstruction, water supplying and draining pipe etc.
