What is a gas ball valve?

Gas Ball Valve – YIXIN

1. Overview

A gas ball valve is a quarter-turn shut-off device specifically engineered for gas applications. Unlike standard liquid ball valves, gas ball valves must comply with strict safety and sealing requirements to handle combustible gases such as natural gas, liquefied petroleum gas (LPG), methane, and other industrial gases.

YIXIN gas ball valves are designed and manufactured to meet or exceed international standards, ensuring reliable performance in both residential and industrial systems. Their compact structure, precision machining, and specialized sealing make them an ideal choice for critical gas control applications.

2. Structure and Design Features

Ball Element
A precision-machined solid or hollow ball with a full or reduced bore, allowing smooth, unobstructed gas flow when open, and a complete shut-off when rotated 90°.
Two-Piece or Three-Piece Body
YIXIN offers two-piece valves for cost-effective, general applications, and three-piece valves for easy maintenance without removing the valve from the pipeline.
Sealing System
Equipped with high-quality PTFE or reinforced PTFE seats, ensuring zero gas leakage under rated conditions. Special sealing designs meet gas-tightness requirements outlined in EN331, ANSI, or API standards.
Material Options
Available in brass, stainless steel, and carbon steel with anti-corrosion coatings. All wetted parts are carefully selected for gas compatibility and long service life.
Connection Types
Threaded (NPT, BSP), flanged (ANSI, DIN), or compression ends to match diverse installation needs.

3. Technical Advantages

Quick and Simple Operation – A quarter-turn handle allows instant opening or closing.
Superior Gas-Tight Seal – Designed for zero leakage to ensure safety in gas distribution systems.
Pressure & Temperature Resilience – Rated to withstand demanding operating conditions without performance degradation.
Maintenance-Friendly – Modular designs enable easy disassembly for inspection and servicing.
Safety Compliance – Meets or exceeds ISO, EN, and API standards for gas service applications.

4. Typical Applications

Residential Gas Systems
Used in gas stoves, water heaters, fireplaces, and home heating systems for fast emergency shut-off.
Commercial and Industrial Gas Supply
Installed in factory gas pipelines, commercial kitchens, and heating plants for safe gas control.
Medical and Laboratory Gas Systems
Suitable for oxygen, nitrogen, and other specialty gases in healthcare and research environments (subject to material compatibility).
HVAC & Energy Systems
Applied in boilers, furnaces, and other heating equipment where precision gas control is essential.
