Ductile iron bellow seat globe valve

Advantage

1.Bellow seal element. The key part of bellow sealed globe valves is metal bellow. It is the connection between cover and stem with automatic roll welding. The metal bellow can keep the stem part no leakage.
2.Benefit from the con and streamline shape design, the disc has a reliable seal and longer service life.
3.Double seal design(bellows+packing). Bellow and packing can protect against leakage and provide a excellent seal.

Ductile iron bellow seat globe valve


cast iron bellow seat globe valve,Steam globe valve (also known as "bellows globe valve"), this valve imported advanced foreign technology, using double bellows design, welded to the stem to maintain stable performance, avoid vibration caused by the valve plug stem vibration.


Under high temperature conditions, the stem does not contact with the medium to ensure that the stem leakage is zero.At the same time ensure enough strength and toughness, can switch tens of thousands of times.The handwheel is ergonomically designed for longer service life and easy and convenient operation.Steam valve opening and closing is plug valve, sealing surfaces appear flat or cone, disc make linear movement along the centerline of the fluid, also known as door and valve is one of the most widely used, it is popular, is due to open and close in the process of friction surface, more durable, opening, manufacturing easy, convenient maintenance, not only suitable for low voltage, and is suitable for high pressure.Widely used in food, medicine, petroleum, chemical, natural gas, steel, environmental protection, papermaking and other transportation pipeline as medium cut off or circulation.


Performance advangate:

1.Bellow is the key part of bellow sealed valves,which is welded to both the valve bonnet and valve stem, with automatic roll welding. The metal bellow can keep the stem part 100% no leakage.

2.Double seal design (bellows+packing). Bellow from a metal seal to prevent leakage,and packing can provide seal if the bellow failed.

3.Overlay welded seat can keep reliable sealing under severe conditions.

4.Ergonomic hand wheel. It provide longer service life and easier Operation.
