Description
DIN cast steel welded globe valves, a kind of DIN globe valves, are mainly utilized for regulating flow in such pipelines as tap water, sewage, construction, petroleum, metallurgy, energy system, etc. They are widely used in such applications requiring throttling and frequent operation.
Advantages of Cast Steel Globe Valve
1. DIN cast steel welded globe valves characterize in good sealing performance, small friction between sealing faces and long service life.
2. DIN globe valves need low torque to open.
3. Valve body is precisely cast.
4. Valve disc is processed by CNC technology.
5. Featuring simple structure, they are convenient to install and maintain.
Features
1. Medium passway of DIN cast steel globe valves is quite zigzag, so the hydraulic resistance is large, leading to big power consumption.
2. When in use, the medium flow direction in DIN globe valves is unidirectional and its flow direction can not be changed.
