Cast iron DIN globe valve,also known as cast iron DIN stop valve, cast iron DIN cutting off valve, is a forced sealing valve. So when the cast iron DIN globe valve is closed, the valve disc of the cast iron globe valve must be pressed by an external force to press the disc close to the sealing surface to realize the sealing effect.
When the media enters the cast iron globe valve from the bottom of the disc, the resistance that the operating force needs to overcome is the friction between the valve shaft and the packing, and the thrust generated by the pressure of the media. The force to close the cast iron globe valve is greater than the force to open the cast iron globe valve, so the diameter of the valve shaft of the cast iron globe valve must be large. Belo Valve is one professional supplier for cast iron globe valve,DIN cast iron globe valve. The shaft material of our cast iron globe valve is 2Cr13 stainless steel, which is strong to meet your working requirements. If the shaft of the cast iron globe valve is not strong enough, it will be bent, then the cast iron globe valve cannot work well any more.
According to different body material used, globe valve can be divided into: cast iron globe valve(GG25 globe valve), ductile iron globe valve(GGG40 globe valve), cast steel globe valve(carbon steel globe valve,WCB globe valve), stainless steel globe valve.
With different end connect, globe valve can be divided into flange end globe valve, threaded globe valve, welded globe valve.

Advantages of cast iron globe valve
1.Compared with gate valve, the structure of cast iron globe valve is simpler, and the cast iron globe valve is more convenient to manufacture and maintain.
2.The sealing surface of cast iron globe valve is not easy to wear and scratch, the sealing performance of cast iron globe valve is good. There is no relative sliding between the valve disc and the sealing surface of the cast iron globe valve body when opening and closing the globe valve. So the wear and scratch are not serious. The sealing performance of cast iron globe valve is great and the service life is long.
3.When opening and closing, the stroke of the valve disc of the cast iron globe valve is small, so the height of the cast iron globe valve is smaller than that of the gate valve, but the face to face structural length of the cast iron globe valve is longer than that of the gate valve.
Disadvantages of cast iron globe valve
1.The opening and closing torque of cast iron globe valve is large, its opening and closing is laborious, and the opening and closing time is long.
2.Cast iron globe valves are not suitable for media with particles, high viscosity, and media easy to coke.
3.The adjustment performance of cast iron globe valve is poor.
