COMMENTS

Due to the risk that the media will enter behind the seats and block the operation of the valve, the seats have to be locked.

Valves which are in constant contact with the heavy black liquor must be equipped with electric heating cable to make sure that the liquid inside the valve body is kept warm during shut down of the plant.

This is an insurance for that the valves are operable at start-up.
