  • Detailed parameters
  • Globe valve, also known as globe valve, is a forced seal valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface does not leak. When the stop valve is opened, the opening height of the disc is 25% ~ 30% of the nominal diameter. The flow has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the fully open position of the stop valve should be determined by the stroke of the valve flap.

    Characteristics of stop valve

    1. Double seal design (bellows packing) If the bellows fails, the valve stem packing will also be avoided;

    2, external leakage, and in line with international sealing standards;

    3, no fluid loss, reduce energy loss, improve the safety of plant equipment;

    4, long service life, reduce the number of maintenance, reduce operating costs;

    5. The durable bellows seal design ensures zero leakage of the valve stem and provides maintenance-free conditions.

    6, bellows seal globe valve with bellows seal design, completely eliminate the common valve stem packing aging and easy to leak the shortcomings, not only improve the use of energy efficiency, increase the safety of production equipment, reduce maintenance costs and frequent maintenance, but also provides a clean and safe working environment.

    The opening and closing parts of the cut-off valve is a plug-shaped disc, which is flat or conical on the seal, and the disc moves linearly along the center line of the valve seat. The movement of the valve stem is straight-through, and there are also lifting and rotating rods, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metals and radioactive media. Therefore, this type of shut-off valve is very suitable for cutting or regulating and throttling. Because of this type of valve stem opening or closing stroke is relatively short, and has a very reliable cut-off function, and because the change of the valve seat port and the stroke of the valve flap are proportional, it is very suitable for the regulation of flow.
