Globe Valve Pressure Seal Bonnet

Globe Valve Pressure Seal Bonnet refers to a type of globe valve that uses a pressure seal bonnet design to close and seal the top of the valve and specifically designed for high-pressure applications.

Component

1. Globe Valve

- A valve used to regulate flow (both shut-off and throttling).

- Flow path is typically “S”-shaped, with a disc that moves vertically to control fluid flow.

2. Pressure Seal Bonnet

- A bonnet sealing design that relies on internal system pressure to enhance the seal between the bonnet and the valve body.

- The higher the pressure, the tighter the seal. it's a self-sealing mechanism.

- Unlike a bolted bonnet, which uses bolts to hold the seal, a pressure seal bonnet is ideal for high-pressure and high-temperature systems, such as in power plants or chemical processing.
