Applications: Pulp and Paper, Power generation, Water and Waste Water, Powder and Bulk Handling, Mining, Chemical, Food and Beverage.
Main Features
- Cast body of one integral piece with internal guides to support the knife and with wedges on both sides to work with fluids in both directions with the same pressure.
- Provides high flow rates with low pressure drop.
- The internal design of the body avoids any build-up of solids in the seat area.
- During the working time of the valve, the knife is in contact with the joints.
- Recommended for water with maximum solid concentration of 5%.
- Two directional arrows in the body show the correct mounting position.
- Polished gate with rounded edges prolongs the working life of the rings and packing.
