Product name：Globe valve with bellows and straight top
Product introduction：
Globe valves to DIN/EN with flanges, welding ends or welding sleeves, with bellows, straight top, check cone or throttle cone, sealing surfaces made of wear- and corrosion-resistant chrome steel or chrome-nickel steel.
Application：
1. Process technology
2. Chemical industry
3. Petrochemical industry
4. Sugar industry
5. Heat recovery device
6. Boiler circulation system
7. Boiler feed water
Advantages：
1. Reliable sealing. The labyrinth cover seal on both sides prevents the sealing gasket from sagging.
2. The system is more energy-efficient. The upper part is short and insulated, so heat loss is minimized.
3. The standard back seal and the downstream safety seal gland made of pure graphite provide additional spindle sealing and blow-out protection during emergency operation.
4. The armored valve seat made of wear- and corrosion-resistant material ensures a long service life and high functional reliability.
5. Easy maintenance due to corrosion-resistant bolts and nuts.
