APPLICATION:
The rubber wedge gate valve is designed to be mounted in hot (max 70°C) and cold water pipe lines and other non-aggressive fluids. The maximum working pressure amount to 16 bar.
The air release valve double float can be installed in water lines in order to let the air exit from the line when loading water, back-to-front let the air flow in the line when emptying the line. Furthermore, when the line works in pressure let the air mixed with the water exit the pipes.
EXECUTIVE CHARACTERISTICS:
The flanges are drilled according to EN 1092-2. The air release valve has a high ratio between the air flowing hole and the nominal diameter DN. The release hole is a journal box in brass to prevent from decay. Ther is also an emptying screw in brass. The balls are covered with an atoxic elastomer.
Average gauge of the epoxy painting: 250 µ.
