product description
The opening and closing part of the electric angle globe valve is a plug-shaped valve disc, the sealing surface is flat or conical, and the valve disc moves linearly along the center line of the fluid. The movement form of the valve stem includes a lifting rod type (the valve stem is raised and lowered, and the hand wheel does not lift), and there is also a lifting rotating rod type (the hand wheel and the valve stem rotate and lift together, and the nut is set on the valve body). Electric angle globe valve is only suitable for fully open and fully closed, adjustment and throttling are not allowed. The electric angle globe valve is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing and the thrust generated by the pressure of the medium. The force of closing the electric angle shut-off valve is higher than that of opening the electric angle shut-off. The force of the valve is large, so the diameter of the valve stem must be large, otherwise the valve stem will be bent. The opening and closing part of the stop valve is a plug-shaped disc, the sealing surface is flat or conical, and the disc moves linearly along the centerline of the fluid. The movement form of the valve stem includes a lifting rod (the valve stem is raised and lowered, the hand wheel does not rise), and there is a lifting rotary rod type (the hand wheel and the valve stem rotate and rise together, and the nut is set on the valve body).
Installation matters
1. The angle-type globe valve handwheel and handle-operated globe valve can be installed in any position of the pipeline.
2. The hand wheel, handle and transmission mechanism of the angle globe valve are not allowed to be used for lifting.
3. The flow direction of the angle globe valve medium should be the same as the valve body
