Product Overview

A one-piece high-temperature ball valve is a robust flow control device engineered to manage the flow of high-temperature fluids in various industrial applications. Its monolithic body design enhances structural integrity, minimizing potential leak paths and ensuring reliable performance under extreme conditions. The valve’s compact structure and reliable sealing make it suitable for applications involving solvents, acids, natural gas, and other general working media. Additionally, it is effective in handling media with harsh working conditions, such as oxygen, hydrogen peroxide, methane, and ethylene.

Product Features

Low fluid resistance with full-bore design for efficient flow.
Compact, lightweight structure for easy installation and maintenance.
Reliable PTFE sealing for complete shutoff.
Quick 90-degree operation for seamless control.
Isolated sealing surfaces prevent erosion.
Handles suspended particles effectively.
Versatile for high vacuum to high-pressure environments.
Cost-effective and durable for extreme conditions.
