Application：

1. Boiler feed water

2. Conventional power plants

3. Petrochemical industry

4. Pipelines and oil storage tanks

5. Refinery equipment

6. Process technology

Advantages：

1. Special anti-twist pins between the valve disc and the handle prevent the seat area from      being changed due to accidental rotation of the valve disc.

2. Due to the unique bolted connection between the valve disc and the handle, the gap can be adjusted to ensure long-term sealing of the seat.

3. The protrusion/groove connection between the housing and the upper part prevents the multi-chamber flat gasket from having unacceptably high pressures on both sides. This results in a longer service life of the flat gasket and better sealing performance.

4. The armored housing sealing surface and the robust valve sealing surface made of wear-resistant and corrosion-resistant materials are suitable for a variety of corrosive and aggressive media, with reliable sealing effect and a long service life.

5. Reduced leakage risk due to the inner shaft

6. Extended wear resistance due to the armored overlay on the valve disc and the seat ring enables longer maintenance-free operation.
