About:

A Hastelloy valve is a type of valve made from Hastelloy, a nickel-based alloy known for its exceptional resistance to corrosion, particularly in harsh and aggressive environments. These valves are used in applications where traditional materials like stainless steel would degrade quickly due to exposure to corrosive chemicals, high temperatures, or extreme pressures. The alloy's unique properties make it ideal for maintaining integrity and performance in challenging conditions.
 

Hastelloy is an alloy primarily composed of nickel, molybdenum, and chromium, with additions of other elements such as iron, tungsten, and cobalt. This composition gives the valve its outstanding resistance to various forms of corrosion, including pitting, crevice corrosion, and stress corrosion cracking. Different grades of Hastelloy, such as C-276, C-22, and B-3, are used depending on the specific requirements of the application. The main pressure-containing parts made from Hastelloy to resist corrosion and wear. Critical moving parts designed to operate smoothly under extreme conditions. Often made from Hastelloy or other compatible materials to maintain a tight seal and prevent leakage.

5. Hastelloy Butterfly Valve
 

Working Mechanism:
The working mechanism of the valves depends on the specific type of valve, but generally follows the principles of their respective designs. For example:
1.Ball Valve: The ball within the valve body rotates to align or block the flow passage. When the handle or actuator turns the ball to the open position, fluid flows through the hole in the ball. When turned to the closed position, the ball blocks the flow.
2.Gate Valve: The gate moves up and down to allow or block the flow. Lifting the gate opens the valve, while lowering it closes the valve, providing a tight seal.
3.Globe Valve: The disc moves perpendicular to the flow, allowing precise control over fluid flow. Adjusting the position of the disc regulates the flow rate.
4.Check Valve: The disc or ball inside the valve body allows fluid to flow in one direction. If the flow reverses, the disc or ball moves to block the passage, preventing backflow.
5.Butterfly Valve: A rotating disc within the valve body regulates flow. When the disc is parallel to the flow, the valve is open. When perpendicular, it is closed.
