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联动, 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.
Specifically for large-size ducts — single valve width can reach several meters
Composed of multiple independent valve bodies for flexible configuration
Solves the problem of no suitable ready-made valves for large ducts
Standard electric actuator (AC220V / DC24V optional)
Manual operation device included — manual control available during power outages
Meets both fire alarm integration and daily maintenance requirements
Blade options: 1.0mm+1.0mm double-layer riveted or 1.5-2.0mm single-layer reinforced
Zinc coating thickness 275g/m² (both sides) for excellent corrosion resistance
Stainless steel seals — leakage rate as low as 0.5%
Standard type leakage rate ≤ 1%
Tight shut-off type leakage rate ≤ 0.5%
Resistance coefficient < 0.5 when fully open — smooth airflow
Oil-impregnated self-lubricating brass bearings — no daily maintenance required
12×12mm galvanized square steel blade shaft — high strength, wear-resistant
16×4mm galvanized flat steel connecting rod — smooth transmission
Operating temperature: -20℃ to 45℃
Galvanized anti-corrosion treatment — suitable for humid, dusty environments
Stainless steel option available for higher corrosion resistance requirements
