Cast Steel Globe Valve is a flange connected valve applicable to nominal pressure PN1.6~PN4.0Mpa, roommate working temperature -29~425 DEG C, chemical, pharmaceutical, chemical fertilizer, the power industry and condition of the pipeline, cut off or connected to medium, suitable for water, oil, steam, acid medium, and the operation mode: manual, gear, electric, pneumatic, etc.
Flange globe valves are forcibly sealed valve. So when closing the valve, exert pressure must be put on disc to make sure sealing face does not leak. When the media goes into the valve from below the valve, the operating force required to overcome the resistance, which is the force created by stem and packing friction and the pressure of the media. When closing the valve, the force is greater than that to open the valve, so the valve rod diameter should be large, otherwise the stem benders occur.
