What is Bellow Sealed gate valve?

Bellows seal valves are valves employed in piping systems to safeguard against leakage. When selected and installed properly, they minimize the risk of potentially harmful chemicals causing injury or illness to workers and damage to the surrounding environment.

How does Bellow Sealed gate valve work?

These valves feature with the bellows cartridge component, welded to the valve stem and bonnet. During the valve the bellows compress or expand along with the sliding stem’s linear motion with little to no friction.

To avoid the leakage of the valve stem, the valve adopts the structure with bellows instead of stuffing boxes generally used for the ordinary valve or the structure with both bellows and stuffing boxes.

A Bellow Sealed gate valve is operated as an obstruction between fluids and the air. At the same time, the valve can prevent fluids leaking to the air and guarantee zero leakage of pipelines.

Where Bellow Sealed gate valves are used?

These valves can be used in Aerospace, Biotechnology, Chemical processing, Fossil power, Nuclear power, Petroleum, Pharmaceutical, Semiconductor manufacturing, Vacuum and ultra-high vacuum.
