Product Introduction

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.

Applicable Locations

The Combination Air Valve is widely used in large space, large duct ventilation and air conditioning systems. Typical applications include:

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.

Product Advantages

1. Designed for Large Cross-Section Ducts

• 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

2. Electric / Manual Dual Drive Mode

• 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

3. Double-Layer Blade Construction — High Strength, Excellent Sealing

• 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%

4. Low Leakage Rate — Significant Energy Savings

• Standard type leakage rate ≤ 1%

• Tight shut-off type leakage rate ≤ 0.5%

• Resistance coefficient < 0.5 when fully open — smooth airflow

5. High-Quality Transmission Components — Reliable Operation

• 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

6. Strong Weather Resistance — Suitable for Harsh Environments

• Operating temperature: -20℃ to 45℃

• Galvanized anti-corrosion treatment — suitable for humid, dusty environments

• Stainless steel option available for higher corrosion resistance requirements
