Cast iron gate valve 111UG DN40 to DN300

Gate valves with soft sealed wedges are designed to close and open the flow of clean liquids, including clean drinking water, non-aggressive sewage, free of solid contamination, at the maximum temperature of medium up to 70°C and the nominal pressure up to 10 bar for valves PN10 and 16 bar for valves PN16. On request gate valves may be adapted to water at the temperature of 120°C, pressure 10 bar. Closing of the gate-valve proceeds by means of a hand wheel and turning the hand wheel in the clockwise direction (when facing the top of the valve). On the Purchaser’s request, the anticlockwise closing is also available. Gate valves described in this catalogue card can be installed in horizontal and vertical pipelines. Gate valves DN250-300 are recommended to be installed only in horizontal pipelines in a vertical position.
