4 Inch Flange Globe Valve Stainless Steel Wcb Manual Corrosion Resistance

Globe valve, also known as shut-off valve, is the most widely used valve. It is popular because of the low friction between the sealing surfaces during the opening and closing process, which is more durable, the opening height is not large, the manufacturing is easy, and the maintenance Convenient, not only suitable for medium and low voltage, but also for high pressure. The closing principle of the shut-off valve is to rely on the pressure of the valve rod to make the sealing surface of the valve disc and the sealing surface of the valve seat closely to prevent the medium from flowing.

The valve plays an important role in cutting off and throttling the medium in the pipeline where it is located. As a very important shut-off valve, the valve is sealed by applying torque to the valve stem. The valve disc exerts pressure to make the valve disc sealing surface and the valve seat sealing surface closely fit to prevent the medium from leaking along the gap between the sealing surfaces.

Structural characteristics of stainless steel globe valve:

The valve plays an important role in cutting off and throttling the medium in the pipeline where it is located. As a very important shut-off valve, the valve is sealed by applying torque to the valve stem.

The valve disc exerts pressure to make the valve disc sealing surface and the valve seat sealing surface closely fit to prevent the medium from leaking along the gap between the sealing surfaces.

The sealing pair of the stop valve is composed of a valve disc sealing surface and a valve seat sealing surface. The valve stem drives the valve disc to move vertically along the center line of the valve seat. During the opening and closing process of the shut-off valve, the opening height is small, the flow rate is easy to adjust, and the manufacturing and maintenance are convenient, and the pressure is applicable in a wide range.

Compared with the other commonly used shut-off valves in industrial production, one by one, the stop valve is simpler in structure than the former, which is easier to manufacture and maintain. In terms of service life, the sealing surface of the shut-off valve is not easy to wear and abrasion, and there is no relative sliding between the valve disc and the seat sealing surface during the valve opening and closing process, so the wear and abrasion on the sealing surface is less, so the seal is improved The service life of the pair of shut-off valves in the fully closed process is small, and the height of the valve is smaller than that of the valve. The disadvantage of the globe valve is that the opening and closing torque is large and it is difficult to achieve rapid opening and closing. Because the flow passage in the valve is relatively tortuous, the fluid flow resistance is large, resulting in a large loss of fluid power in the pipeline.
