Sealed valve flange globe valve belong to mandatory, so the valve is closed, must be pressure on the disc, to force a sealing surface does not leak. When medium by disc below into the valve 6, the operating force needed to overcome the resistance, is stem and packing of the friction force and the thrust produced by medium pressure, close the valve strength is stronger than open the valve, so it's bigger, the diameter of the stem or stem top bending failure happens.
In recent years, from the valve seal, flange globe valve is replaced by the disc above the medium flow direction into the valve cavity, in the medium pressure at this moment, close the valve of the force is small, and the strength of the valve, the valve stem diameter can be reduced accordingly. At the same time, in the role of media, this kind of valve is tight. Valve in China "three for" regulation, the flow of cut-off valve, shall be applied. The cut-off valve opens, the opening of the disc height, is 25% ~ 30% of nominal diameter, flow has reached maximum, said valve to full open position. So stop valve fully open position, should be determined by disc's schedule. This valve shall generally be installed in the pipeline.
