Ball Valves
Directly from Our Factory to Your Project
Your Custom Ball Valve Solutions
As a specialized ball valve manufacturer in China with 36 CNC Centers, YAYE delivers API 608 ball valve solutions that bridge the gap between high-end quality and factory-direct efficiency.
Enhanced sealing for fluid control in demanding applications.
Reliable valve with free-floating ball for secure fluid handling.
Ball Valve Solutions for the Global Industrial Flow Challenges
In the complex ecosystems of Upstream, Midstream, and Downstream operations, a valve is a safety barrier. As an integrated R&D and manufacturing hub, YAYE engineersforged steel ball valves, flanged floating ball valves, and trunnion-mounted ball valves for oil & gas, chemical, power generation, and water treatment projects worldwide:
Manufacturing You Can Trace and Trust
Direct manufacturing control is the secret to our 0.2% repair rate. While others manage supply chains, we manage the metal:
One-Step Machining Strategy
We utilize a "one-time processing" method for ball valve bodies. By eliminating multiple clampings, we ensure absolute concentricity between the seat and the ball, creating a perfect seal.
Mazak-Powered Consistency
Our 36 Mazak CNC Centers produce ball valves with a superior surface finish, reducing friction and extending seat life by up to 40% compared to conventional machining.
Total Transparency
From raw material spectrometer testing to final high-pressure seat leakage tests, every step is performed in-house for 100% traceability.
