The main materials of J41Y high pressure stainless steel stop valve are: CF8, CF3, CF8M, CF3M, 2520, duplex stainless steel, G1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti and so on. Products are mainly used in petrochemical, chemical, electric power, metallurgy, medicine, food and other industries.

J41Y high pressure stainless steel globe valve is a forced seal valve, so when the valve is closed, pressure must be applied to the valve disc to force the sealing surface not to leak. When the medium enters the valve from below the valve disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and the packing force and the thrust generated by the pressure of the medium. The force of closing the valve is larger than the force of opening the valve, so the diameter of the valve stem should be large, otherwise the failure of the top bend of the valve stem will occur. In recent years, after the appearance of the self-sealing valve, the medium flow of the stop valve is changed from the top of the valve disc into the valve chamber, then under the action of the medium pressure, the force of closing the valve is small, and the force of opening the valve is large, and the diameter of the valve stem can be reduced accordingly. At the same time, under the action of the medium, this form of valve is also more tight. China's valve "three to" has stipulated that the flow of the globe valve, all top-down.

J41Y high pressure stainless steel globe valve structure features:

1, advanced structure, reliable sealing, excellent performance, beautiful shape. It improves the steel of the valve stem, significantly reduces noise and vibration, and improves the service life and performance of the valve.

2, the globe valve can be installed in any position of the pipeline, the medium from the bottom to the upstream.

3, DN250 more than the use of advanced multi-seal, double support, the use of guided movement (can greatly improve the resistance to water hammer impact), the medium from above to enter, better solve the large diameter globe valve opening and closing torque, seal can not be closed strictly, the packing room running, effectively improve the valve performance and scope of use. (The "closed" torque is 10% of the ordinary valve, and the "open" torque is 3% of the ordinary valve).

4, stainless steel stop valve is suitable for all kinds of corrosive media on the pipeline, has good corrosion resistance and enough strength.

5, alloy steel stop valve is suitable for high temperature steam, oil pipelines, with high temperature resistance.

Products are mainly used in petrochemical, chemical, electric power, metallurgy, medicine, food and other industries.
