Response speed < 1 second; air volume control accuracy ≤ ±5%; no straight pipe sections are required before and after the valve;

Valve body material: aluminum alloy spinning, one-time molding, the inner and outer walls are sprayed with epoxy resin (Teflon can also be sprayed on demand); valve stem material: 304 stainless steel + Teflon spraying, bracket 304 stainless steel, corrosion-resistant, good consistency;

Pressure independence: Self-adjusting mechanical structure, the air volume within the pressure range of 150pa ~ 750pa has nothing to do with the static pressure in the pipeline; suitable for exhaust or fresh air supplementary air, fume hood exhaust, room exhaust, etc. that require high air volume accuracy

The electric valve is equipped with a 3s1OON linear actuator, 2~10v analog feedback;

The variable air volume valve is equipped with a 3s1OON integrated control actuator, 2~10v control and feedback, and supports 485 Modbus RTU communication

Basic principle:

Pressure-independent control : All valves perform self-operated dynamic adjustment to static pressure changes to maintain a fixed air flow rate. Each valve has a cone assembly with a spring designed to compensate for changes in duct pressure.

Why choose aluminum alloy venturi valve

Automatic constant air volume control

Using the Venturi principle and mechanical self-balancing structure, it automatically compensates for system pressure fluctuations and maintains stable air volume.

No external power required

The standard model does not require power drive, which can achieve long-term stable operation and reduce maintenance costs.

High-strength aluminum alloy structure
