Cast iron/ductile iron DIN bellows sealing globe valve OEM supplier

Bellows sealing globe valve is also called bellows globe valve, steam bellows globe valve, is one kind of forced sealing valve, widely used for various industrial pipeline systems to cut off, control the media flow. 

Bellows sealing globe valve is also one kind of globe valve, according to different body material used, bellows sealing globe valve can be divided into cast iron bellows sealing globe valve, ductile iron bellows sealing globe valve, cast steel bellows sealing globe valve. 

The ductile iron bellows sealing globe valve is manufactured by foreign advanced technology and adopting foreign metal bellows sealing technology. The bellows sealing globe valve is using the high performance elastic metal bellows to achieve the sealing effect, which has a longer service life. The design of the bellows sealing completely eliminates the weakness of the aging and easy leakage of the stem packing sealing of the ordinary valves. That bellows sealing design not only improves the energy efficiency, increase the safety of production of globe valves , reduces maintenance cost and frequent maintenance, but also provides the clean,safe working environment. 

Introduction of DIN cast iron/ductile iron bellows sealing globe valve

Cast iron/ductile iron bellows sealing globe valve features: 

1.The ductile iron bellows sealing globe valve is using the double sealing design(bellows sealing and gland packing sealing). if the bellows sealing fails, the stem packing will work to avoid the sealing leakage. 

2.The cast iron/ductile iron bellows sealing globe valve has reasonable structure, reliable sealing, excellent performance and beautiful appearance. 

3.The ductile iron bellows sealing globe valve has no fluid loss, which reduces the energy loss and improves the safety of the device. 

4.The sealing surface of the ductile iron bellows sealing globe valve is welded hard alloy, which is wear resistant, corrosion resistant, and friction resistant and has a longer service life. 

5.The ductile iron bellows sealing globe valve is using the strong and durable bellows sealing design, which ensures the zero leakage of the valve stem and provides maintenance-free conditions. 

6.The valve stem of the ductile iron bellows sealing globe valve is nitrided, which has good anti-corrosion and anti-friction advantages. 

7.The lifting position of the valve stem of the ductile iron bellows sealing globe valve can be seen obviously.
