Flomatic introduces next generation compact combination air valve
Glens Falls, NY (Flomatic Valves release) — Flomatic Valves recently announced the official release of the new Sewair‑Combo NXC, a Next Generation Compact (NXC) combination air valve engineered to provide reliable air release, vacuum protection and continuous air management in municipal and industrial wastewater systems.
Designed in accordance with AWWA C512, the Sewair‑Combo NXC helps improve hydraulic efficiency while protecting critical pipeline infrastructure from damaging air-related conditions.
Effective air management is essential to the performance and longevity of wastewater collection systems and force mains. Entrapped air can restrict flow, increase pumping costs, contribute to surge conditions and accelerate wear on system components, while vacuum conditions can place pipelines at risk of collapse and column separation. Ideally suited for wastewater force mains with changing slopes and critical high points where air pockets commonly accumulate, the Sewair‑Combo NXC provides a reliable solution for maintaining system efficiency, improving operational reliability and safeguarding valuable infrastructure assets.
The Sewair‑Combo NXC combines three essential functions into a single compact, full-bore solution:
- Automatically releasing large volumes of air during pipeline filling
- Admits air during pipeline draining or sudden flow interruptions to prevent vacuum conditions
- Continuously releases entrapped air while the system remains under pressure
Engineered specifically for demanding wastewater service, the Sewair‑Combo NXC features a powder fusion-bonded epoxy coated ductile iron body, 316 stainless steel float and stainless-steel internal components that provide superior corrosion resistance in aggressive sewage environments. Its innovative sloped, funnel-shaped lower body helps minimize the accumulation of grease and debris, supporting dependable operation and reducing maintenance requirements. Designed with serviceability in mind, the valve incorporates two cleanout and drain ports that simplify inspection, draining, testing, and backflushing procedures. Available in a 2-inch NPT configuration and rated for operating pressures from 3 PSI to 230 PSI, the Sewair‑Combo NXC delivers dependable, low-maintenance air management and infrastructure protection across a wide range of municipal and industrial wastewater applications.
