RISING STEM CAST IRON FLANGED GATE VALVE
The 30h6br gate valve is designed to be installed on a pipeline as a shut-off device to block the flow of the working medium. The sealing surfaces of the housing and discs are made of brass (bronze). When closing the 30h6br gate valve, the spindle lowers the discs and the wedge, which, resting on the bottom of the housing, unclenches the discs and creates tightness on the sealing surfaces. The use of a gate valve as a regulating device is not allowed. Working medium: water, steam.
The 30h6br gate valve is available in nominal diameters: DN 40, DN50, Dn65, Dn80, Dn100, Dn125, Dn150, Dn200, DN250, Dn300, Dn350, Dn400, Dn450, Dn500.
