Yoke Type Air Vacuum Release Valve China Factory and Suppliers
The Yoke Type Air Vacuum/Release Valve is a high-performance industrial solution engineered for the efficient management of air and vacuum within piping systems. Designed to meet rigorous international standards including AWWA C512, EN1074-4, and CJ-T 217, this valve ensures optimal system pressure regulation by automatically releasing air during filling and admitting air during draining to prevent vacuum-induced pipe collapse.
Constructed from premium-grade stainless steel (CF8M/CF8) and featuring versatile sealing options like EPDM, NBR, and PTFE, our yoke-type valves offer exceptional corrosion resistance and durability. Whether deployed in water distribution, industrial processing, or wastewater management, these valves provide a reliable, leak-proof seal and seamless integration with global flange standards such as EN1092 and ASME B16.5.

Frequently Asked Questions
These valves are primarily used in water distribution and industrial piping to release trapped air during filling and admit air during drainage, preventing pipe bursts or collapses due to pressure surges or vacuums.
For highly corrosive chemical environments, we recommend PTFE sealing seats due to their exceptional chemical inertness and temperature stability compared to EPDM or NBR.
Yes, our valves are manufactured to support both EN1092 and ASME B16.5 flange standards, ensuring seamless integration into global piping infrastructures.
CF8M is a molybdenum-bearing austenitic stainless steel that provides superior resistance to pitting and crevice corrosion, significantly extending the valve's life in saline or acidic conditions.
We provide a wide range of pressure ratings including PN10, PN16, and CLASS 125/150 to suit various industrial and municipal pressure requirements.
As specialists in metal products manufacturing and casting, we can customize materials and dimensions according to your specific engineering drawings and project needs.
