Product Introduction
Bellow seal globe valves are normally installed in a working condition that has strict emission requirement and once emission happens, it will incur harmful influence to person and environment. This type of valve is achieved by mounting a metal bellow between the bonnet and the stem. Bellow will be driven to scale up and down when stem moves, which will eliminate possible leakage arising from stem movement.

FAQ
Q: What is the advantage of Global Valves with bellow seal?
A: For some working conditions that has strict emission requirement and once emission happens it will incur harmful influence to person and environment. This type of valve is achieved by mounting a metal bellow between the bonnet and the stem. Bellow will be driven to scale up and down when stem moves, which will eliminate possible leakage arising from stem movement.

Q: Can this bellow seal globe valve be used for toxic or inflammable fluids?
A: Yes, if with high corrosion resistant valve bodies made of austenitic stainless steel and leak-free stem design, valves are almighty to handle toxic or inflammable fluids, steam and heat transfer media, as well as vacuum service.
