Bidirectional Knife Gate Valve

 Serie GD

 

DESCRIPTION:

Slurry Valves

Slurry valve for very loaded products with solids, used for suspended matter in mining. It does not present neither salient nor any split in the pipe. It is not needed any joint between the flanges as it is incorporated in the body.

• Bidirectional wafer‐design knife gate valve.
• Monoblock one‐piece cast iron body.
• Stainless steel gate. Two rubber sleeves.
• Provides high flow rates with low pressure drop.
• Various seat materials available.

This valve main characteristic is that it provides a full continuous flow.

The GD valve’s body is composed of one single “monoblock” piece.
