Stainless Steel Combination Air Valve for Sewage Water China Factory Suppliers
Our Combination Air Valve for Sewage Water is a high-performance, triple-function solution engineered specifically for the demanding environments of wastewater management. Integrating air release, air intake, and micro-exhaust functions under pressure, this valve ensures optimal pipeline efficiency by preventing vacuum formation and eliminating trapped air pockets that can obstruct flow.
Crafted with a full stainless steel construction for superior corrosion resistance, the valve features a specialized 2.0mm small orifice to guarantee rapid air release. Whether utilized in municipal sewage systems or industrial waste treatment, our valves provide a robust, leak-proof seal and long-term operational reliability in the most aggressive chemical environments.

Frequently Asked Questions
It performs three critical roles: releasing air during pipeline filling, admitting air during draining to prevent vacuum collapse, and exhausting small amounts of air that accumulate during normal operation.
Sewage water contains aggressive chemicals and sulfides. Stainless steel (SS304/SS316) provides the necessary corrosion resistance to prevent premature valve failure and leaks.
Our valves are designed and tested according to AWWA C512, EN1074-4, and CJ-T 217, ensuring global compatibility and quality.
Yes, besides stainless steel, we offer Duplex and Titanium options upon request for highly specialized industrial casting and processing needs.
The small orifice is engineered to allow for rapid air release under pressure, which is essential for maintaining smooth fluid flow and avoiding pressure surges in the pipe.
We support a wide range of Incoterms, including EXW, FOB, CRF/CIF, DAP, and DDU, to provide flexible logistics for our global clients.
