Product name:Flange stop valve with bellows
Product introduction:
Globe valves to DIN/EN with flange, bellows, straight tip, shut-off cone or throttle cone, standard position indicator with colour coding for version differentiation, replaceable cone, bellows protection when valve is fully open, sealing surfaces made of wear- and corrosion-resistant chrome and chrome-nickel steels.
Application:
1. Hot water heating equipment
2. Air conditioning equipment
3. Boiler feed water
4. Boiler circulation system
5. Chemical industry
6. Process technology
7. Heat recovery equipment
8. Sugar industry
Advantages:
1. Position indicator with stroke limitation and fixing outside the thermal insulation provides high operating convenience at no extra cost. The valve position can be read at any time.
2. The standard throttling cone up to DN 100 enables optimal start-up and throttling, and the top cone as seat guide is available as an option for the most difficult throttling situations in all nominal diameters.
3. Increased safety against pressure surges when the valve is fully open by means of a bellows with chamber.
4. The cost-effective short and smooth upper part can be thermally insulated, so that heat losses are low during operation.
5. Increased reliability against vibration damage. The bellows is welded to the spindle, so that no vibrations are transmitted from the cone to the bellows.
6. Additional safety by means of a downstream safety seal gland in the event of a bellows rupture.
7. The color coding system of the position indicator prevents confusion when changing. The cone design and the cone seal are visible from the outside of the thermal insulation.
8. The non-rising handwheel saves space.
9. The interchangeable cone reduces maintenance costs. When replacing the cone, it is not necessary to replace the entire upper part.
