Bellow Seal Globe Valve advantage:
1. The GS-C25 Flanged DIN Standard Bellow Seal Globe Valve has a simple structure and is easy to manufacture and maintain.
2. The working stroke of the globe valve is small and the opening and closing time is short.
3. The globe valve has good sealing performance, low friction between sealing surfaces, and a long service life.
The types of Bellow Seal Globe Valves are divided into external thread globe valves and internal thread globe valves according to the position of the valve stem thread. According to the flow direction of the medium, there are straight through globe valves, DC globe valves, and angle globe valves. Globe valves are divided into packing sealed globe valves and bellows sealed globe valves according to their sealing forms.
