The pressure seal forged steel globe valve's design incorporates a metal-to-metal seal that becomes tighter as the pressure increases, the initial preload deforms the taper on the soft iron gasket to mate with the taper on the bonnet, the thin knife-edge on the gasket is wedged tightly between the body and the bonnet, the shallow angle insures that the gasket is sealed tightly with only a small upward force on the bonnet. Once the initial seal is created, the body/bonnet joint will remain leak free regardless of thermal or pressure conditions in the valve, after the joint has been assembled, there is no need to adjust bonnet cap screws.Application standard 1, design & manufacturer confirm to : API 602; BS5352;ASME B16.342, socket weld end dimension according to ANSI B16.113, inspection and test confirm to API 5984, main material : A105;LF2;F5;F11;304(L);316(L);F347;F321;F51;Monel;20#alloy steel5, pressure : 1500 class, 2500 classDimension for 900-1500class ( ASME B16.34 design standard )SizeF.P1/2''3/4''1''1 1/4''1 1/2''2''Face to faceL140140140178178216Hand wheelw220220220280280300HeightH320320320440440490Flow portd121520283240Weight(kg)1010.81219.621.130 url:http://www.hugo-valves.com |
