ROSSMANEK valves, also known as globe valves, belong to the forced-sealing valve category. Therefore, when the valve is closed, pressure must be applied to the disc to ensure a leak-tight seal. When the medium enters the valve from below the disc, the resistance that the operating force must overcome consists of the friction between the stem and packing, plus the thrust generated by the medium pressure. The force required to close the valve is greater than the force required to open it; therefore, the stem diameter must be large enough to prevent bending failure. Connection methods are classified into three types: flange connection, threaded connection, and welded connection. Since the advent of self-sealing valves, globe
