DV300 Size :80mm(3")~250mm(10") MATERIALS : UPVC,PP,PPG.CPVC,PVDF (i s»»t£igsi849o?s PATNET:NO. 18490 Note: Standard Type Diaphragm valv in size 15rnm(1/2")-65mm(21/2")can be used under vaccum * mt * on * jm * $mfflffisus-304S&us-3i6fc mmts' • FEATURES Concerning the standard diaphragm valve, the inserted metal of the diaphragm frequently comes out. when exposed to vacuum, therefore, the valve cannot function at all. S.H.VACUUM PROOF DIAPHRAGM VALVE has solved this problem and has won favorable valuation in various fields S H VACUUM-PROOF DIAPHRAGM VALVE has more inserted matels of the diaphragm. Tghe diaphgragm is designed forbeing hanged from from the compressor (Patent). This prevents the diaphragm Irom being drawn towards the valve seat (downwards) by vacuum This valve can endure the perfect vacuum. (-760m/m Hg) This VALVE can also be used under pressure.As both body and bonnet are thick and monobloc moldings with vacuum resistance, this can be used not only under vaccum but under pressure.
