    Product Features:

    1. Dual-eccentric structure minimises friction at sealing surfaces, achieving instant disengagement upon opening.

   2. Metal-to-metal hard sealing with carbide-clad sealing surfaces ensures superior sealing performance, wear resistance, and extended service life.

  3. Bidirectional sealing capability allows sealing in both forward and reverse directions, facilitating straightforward installation and flexible operational conditions.

   4. Incorporates a floating seat design with self-centring and wear compensation functionality.

   5. Valve disc employs a trunnion structure for high strength, excellent rigidity, and minimal deformation under pressure.

   6. Sealing surfaces resist scaling and possess self-cleaning properties.

 

    Nominal Diameter: DN100–DN1600   

    Operating Temperature: -29–200°C
