Amidst the backdrop of climate change and the imperative to adopt renewable and environmentally friendly energy sources, there's a burgeoning demand for power generation. This necessitates a closer examination of industrial valve manufacturing within the power plant sector, aiming to enhance efficiency and optimize performance.

Though valves may seem like minor components within the expansive infrastructure of a power station, their significance is paramount. Within a single power plant, numerous valves play diverse roles, collectively contributing to its operations.

While the fundamental design principles of valves remain consistent, advancements in materials and manufacturing techniques have led to significant improvements. Consequently, modern valves operate with greater sophistication and efficiency. This article aims to shed light on the importance of valves within power plants, as well as their various classifications.

Bolted Bonnet and Pressure Seal Globe Valves

The globe valve, akin to the gate valve but featuring a spherical disk instead of a wedge-shaped one, serves the functions of shut-off, regulation, or throttling of media flow. Predominantly utilized for throttling, globe valves exhibit limitations in handling high-flow-rate media.

In power generation applications, globe valves excel in flow control, boasting a straightforward design that facilitates maintenance. The inherent low friction of their design contributes to prolonged service life.

Key considerations in selecting globe valves include the nature and velocity of the medium, as well as the desired level of control. Furthermore, factors such as the seat, disk, and operational mechanisms should not be overlooked.

a. Pressure Seal Globe Valve

For high-pressure applications, components like the disk, seat rings, and backseat require hard-facing to ensure durability.

b. Bolted Bonnet Globe Valve

Commonly employed for throttling services, bolted bonnet globe valves necessitate thicker cast sections in high-stress areas. Welded seat rings are essential to minimize leakage risks.
