J41H-16C stainless steel boiler steam high temperature flange Industrial Globe Valve DN25 50 65 80 100 150

The opening and closing parts of the stainless steel flanged globe valve are plug-shaped discs, the sealing surface is flat or conical, and the discs move linearly along the center line of the valve seat. The movement form of the valve stem, (common name: dark rod), also has a lifting and rotating rod type, (common name: rising rod) a stop valve refers to a valve whose closing part (disc) moves along the center line of the valve seat. According to this movement form of the valve disc, the change of the valve seat port is proportional to the valve disc stroke. Because the opening or closing stroke of the valve stem of this type of valve is relatively short, and it has a very reliable shut-off function, and because the change of the valve seat port is in direct proportion to the stroke of the valve disc, it is very suitable for flow adjustment. Therefore, this type of shut-off valve is very suitable for shutting off or regulating and throttling.

The stainless steel flanged globe valve is suitable for various corrosive media pipelines, with good corrosion resistance and sufficient strength. The alloy steel globe valve is suitable for high temperature resistant steam and oil pipelines, and has the characteristics of high temperature resistance. Stainless steel flanged globe valves are mainly used in petrochemical, chemical, electric power, metallurgy, medicine, food and other industries.

Structural features

1. Advanced structure, reliable sealing, excellent performance and beautiful appearance. Improve the stiffness of the valve stem, significantly reduce noise and vibration, and improve the service life and performance of the valve.

2. The stop valve can be installed at any position of the pipeline, and the medium flows from bottom to top.

3. Advanced multi-seals, double supports above DN250, guided movement (which can greatly improve resistance to water hammer impact), and the medium enters from above, which better solves the problem of large opening and closing moments of large-diameter globe valves, and the sealing cannot be tightly closed. The filling chamber is running out, which effectively improves the performance and use range of the valve. (“Close” torque is 10% of ordinary valve and “open” torque is 3% of ordinary valve).

4. The stainless steel globe valve is suitable for pipelines with various corrosive media, with good corrosion resistance and sufficient strength.

5. The alloy steel globe valve is suitable for high temperature resistant steam and oil pipelines, and has the characteristics of high temperature resistance.
