| High Light | ZF Series air valve for petrochemical plants ，combination air valve with warranty ，fire dampers for industrial plants | ||
The Combination Air Valve (ZF Series) is an electric modular air volume control device specifically designed for large-space HVAC systems. It consists of a bottom frame, multiple independent valve bodies, an actuator, and a transmission mechanism. Manufactured from galvanized steel sheet, the blades can be constructed as double-layer riveted or single-layer reinforced structures. Controlled via a connecting rod mechanism for multi-blade linkage, it is ideal for subway tunnels, large warehouses, petrochemical plants, large coal mines, and other applications requiring large cross-section duct air volume regulation.
The Combination Air Valve is widely used in large-space, large-duct ventilation and air conditioning systems. Typical applications include:
| Facility Type | Specific Application |
|---|---|
| Subway Tunnels | Tunnel ventilation systems, smoke exhaust duct isolation and regulation |
| Large Warehouses | Logistics center ventilation system zone control |
| Petrochemical Plants | Chemical plant and tank area ventilation system air volume regulation |
| Large Coal Mines | Mine ventilation system duct control |
| Commercial Complexes | Large shopping malls, underground garage ventilation zone management |
| Public Buildings | Stadiums, exhibition centers, theater HVAC systems |
| Industrial Plants | Large-span workshop ventilation system air distribution |
| Power Facilities | Power plant and substation ventilation system duct control |
Core Value: Designed specifically for large cross-section ducts, the Combination Air Valve integrates multiple small air valves into one unit for unified control — saving installation space while ensuring precise and reliable air volume regulation.
