Ball Valve Solutions

High-Performance Industrial Ball Valves for Severe Service

Your Partner for Zero-Leakage Fluid Control Solutions

As a national high-tech enterprise and a leading integrated manufacturer, YONCO  engineers and delivers robust ball valves designed for critical on/off and throttling applications.

From cryogenic temperatures (-196°C) to ultra-high pressures (4500Lb / 76MPa), the integrity and safety of your project are our top priorities. We ensure precise fluid isolation through 90° fast-acting rotation and guaranteed positive shut-off.

Versatile Ball Valves for Every Industrial Requirement

We offer a comprehensive range of industrial ball valves to perfectly match your specific media, temperature, and pressure requirements.

Our product portfolio includes Floating Ball Valves, Trunnion-Mounted Ball Valves, Metal-Seated Ball Valves, and Fully Welded Ball Valves, available with manual, pneumatic, or electric actuation.

  • Pressure Rating: 150Lb to 4500Lb (PN10 to PN420, up to 76MPa) — Delivering reliable performance in high-pressure pipeline applications.
  • Temperature Range: -196°C to 816°C — Suitable for cryogenic, high-temperature, and extreme temperature applications.
  • Size Range (DN): DN10 to DN4000 (1/2" to 160") — Capable of accommodating large-diameter project requirements.

Solve Your Toughest Flow Challenges with Advanced Materials

The integrity of your fluid control system hinges on the valve material. We utilize a dedicated material selection process to eliminate chemical and thermal compatibility risks in your critical lines.

Corrosion Resistance

Utilize Duplex Steel (F51, F53) and high-grade stainless steel to significantly extend valve life in acidic or chloride-rich environments, minimizing costly downtime.

Extreme Durability

For highly aggressive media, we offer Special Alloys including Inconel, Monel, and Hastelloy, ensuring the valve structure withstands high-purity or highly corrosive media.

Precision Sealing

Our Metal Seated Ball Valves are crafted through CNC precision machining and advanced lapping/polishing techniques, achieving superior shut-off even after thermal cycling or abrasive wear.

Safety & Compliance

Every Ball Valve is subject to strict testing (e.g., API 6D, API 608) and backed by CE and SIL certifications to guarantee operational safety.

Precision Manufacturing

Your Ball Valve is a critical safety component, and it is manufactured on our 41,000㎡ production floor with unmatched precision. Our integrated manufacturing process ensures total quality control from raw material to final shipment.
