A Bellow Sealed Valve, also known as a ‘Zero-Leak Valve’ is a specially designed industrial valve that was developed in response to the need for a completely new way to provide the necessary sealing for use in industries that deal with toxic media, where even minor leaks can be disastrous.
The bellow cartridge contains a number of convolutions, which are compressed or expanded depending on the movement of the valve stem. When the valve is in the open position, the bellow is compressed, and when the valve is in the closed position, the bellow is expanded.
Advantages:-
- It has a double seal that consists of packing and bellows.
- It decreases medium fluid loss and advances environmental and safety protection.
- It has the ability to save energy because it works to cut down on leakage-related energy losses.
- The valves last a long time.
- There is a significant reduction in the cost of operation and maintenance.
- It makes sure that the valve stem is not leaking, enabling maintenance-free operation.
Applications
- High integrity pressure protection system
- Handling solids (powders, fines, dust, and catalysts)
- Coal conversion and gasification
- Coal conversion and gasification
- Compressor stations
- Systems for separating, filtering, and drying
What is globe valve?
A globe valve controls a pipeline’s flow. The movement of liquid or gas via a pipe is managed or stopped using it. The name “globe valve” refers to the spherical shape of the body, which is divided into two halves by an internal baffle. It is also known as throttle valves
A disc or plug is used to cover the globe valve’s opening in the seat, which is located in the middle and parallel to the pipe. It consists of a rotating disk-like component and a fixed ring seat inside of an usually spherical body.
