SS304 bellow seal globe valve

An SS304 bellow seal globe valve is a type of valve that uses bellows to seal the valve stem and prevent leakage. The valve body and trim (internal parts that meet the fluid) are made of SS304 stainless steel, a type of steel that is resistant to corrosion and can withstand high temperatures. The globe valve is a type of valve that controls the flow of fluid through a pipe by using a movable disc that can block or restrict the flow. The bellows seal allows for a tighter seal, which can increase the valve’s ability to control the flow of fluid and reduce leakage.

The SS304 bellow seal globe valve works by using a movable disc that sits inside the valve body and can be raised or lowered to control the flow of fluid through the valve. The disc is connected to a stem, which is in turn connected to an actuator (such as a handle or a motor) that can be used to control the position of the disc. When the valve is open, the disc is raised and allows fluid to flow through the valve. When the valve is closed, the disc is lowered and blocks the flow of fluid.

The bellows seal is located between the stem and the valve body, and its purpose is to prevent leakage between these two components. The bellows is a flexible, tubular pieces of metal that can expand and contract as the stem moves up and down. This allows the stem to move freely without allowing any fluid to leak past it. The bellows also protect the stem from any corrosive or abrasive fluids that may be present in the pipeline.

Advantages of SS304 bellow seal globe valve:

  • It provides a tight, leakproof seal between the valve stem
