High-pressure forged steel ball valves are specially designed for high-pressure pipeline systems, primarily used in long-distance pipeline transportation of oil, natural gas, and urban gas pipeline systems. Their design takes into account factors such as pipeline stress resistance, safety, weather resistance, and reliability for long-term use.

Working Principle

The working principle of the high-pressure forged steel ball valve is to control the opening and closing of the valve by rotating the valve stem. It is typically a full-bore ball valve with a 90-degree angle switch, featuring a simple structure, compact size, and the capability to be made in large diameters. It offers reliable sealing and is easy to operate with lightness and flexibility.

Primary Material

The main materials of the high-pressure forged steel ball valve include:

Carbon Steel: Such as A105, WCB, with excellent mechanical properties and corrosion resistance.

Stainless Steel: Grades 304, 316, 316L, suitable for corrosive media.

Alloy steel: such as A182 F11, A182 F22, suitable for high-temperature and high-pressure environments.

High-Temperature Alloys: Such as A182 F91, A182 F92, suitable for high-temperature conditions.

‌Tantalum Alloys: such as Ta10, Ta2.5, suitable for special corrosive media.

Nickel-based alloys: such as Inconel 625, Hastelloy C276, suitable for high temperatures and corrosive media.

Features

High-pressure resistant: Made from forged steel, offering exceptional strength and pressure-bearing capacity.

Corrosion-resistant: Special materials are used for components like spheres and valve seats, offering strong corrosion resistance.

High-Temperature Resistant: Engineered with special materials for use in high-temperature environments.

Good sealing: The tight fit between the sphere and valve seat prevents medium leakage.

‌Operation is light and easy: Simple structure, easy to install and maintain._

Application Fields

High-pressure forged steel ball valves are widely used in long-distance pipeline transportation of oil, natural gas, and urban gas pipeline systems. They are also suitable for other industrial pipeline systems, such as controlling fluids like air, water, and steam in thermal power plants.
