Knife Gate Valve - T200 - BIDIRECTIONAL | Zubi

The Knife Gate Valve - T200 - BIDIRECTIONAL by Zubi is a robust and versatile valve designed for efficient flow control in various industrial applications. This valve is engineered to handle both directions of flow, making it ideal for systems where flow direction may change. Its knife gate design ensures a tight seal and reliable operation, even in challenging conditions with viscous or abrasive media. The T200 model is constructed with high-quality materials to ensure durability and longevity, providing a cost-effective solution for industries such as mining, wastewater, and pulp and paper.

Datasheet and documents

Description

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.
