Product Description
The Venturi airflow control valve combines a mechanical, pressure-independent regulating valve with a high-speed position/airflow controller to meet the unique needs of airflow control. Through aerodynamic design, the valve has a quiet working performance. Quick response automatic pressure balance device. Provide reliable fume hood dust collection and indoor pressure control, and the air volume control is not affected by the fluctuation of the ventilation system.
 
Valves are classified into applications such as Constant Air Volume(CAV) control, bistable control or Variable Air Volume(VAV) control. In the design, the airflow should be maximized and the related noise should be reduced.
 
* Pressure-independent operation: self-adjusting mechanical components, the air volume has nothing to do with the pressure change in the pipeline
* Fast response speed: the response time is less than 1 second
* High control accuracy: air volume control accuracy ≤±5% (within the range)
* High adjustment ratio: up to 20:1
* Automatic window function, convenient to open the window when holding items in both hands
* Air flow control range: 60~17,000m3/h
* Air volume calibration: The air volume is accurately calibrated at 51 points in the factory
* No straight pipe section is required for the air ducts before and after the valve
* Working pressure: 150Pa~750Pa
* A variety of mode control methods, suitable for various integrated control systems
 
 
 The new generation of stainless steel Venturi valve has changed the traditional air volume control mode, adding flow, pressure, measurement and control to the original imported Venturi valve. For high-precision and low-pressure applications, the original imported and domestic Venturi valves using spring adjustment cannot meet the requirements of use. Because the spool is at low pressure, the spring cannot sense pressure changes. The new generation of flow control type Venturi internal Imported ultra-high-precision controlled, the valve pressure loss is smaller, and the system accuracy and stability are increased Performance, bringing the system to a higher level, saving energy and reducing emissions. In terms of material, SS304 stainless steel with better performance is used for main structural parts such as valve body, valve core, bracket, etc.; therefore, it has better indicators of corrosion resistance, material stability, mechanical strength, etc., especially suitable for clean environment Air supply/exhaust system and P3/P4 laboratory; more stringent requirements for corrosion resistance, material stability, mechanical strength, and gas leakage.

Controller
The fume hood controller is installed on the fume hood. It is mainly used for the measurement and control of the wind speed of the fume hood, lighting monitoring and alarming, and parameter setting. It cooperates with the Venturi valve to realize the air volume control and monitoring and alarming of the fume hood.
Door height sensor
The door height sensor is used to detect the position of the fume hood adjustment door. The sensor can be configured to operate with the modulating door found on most VAV fume hoods. When the door moves, the reel and potentiometer will turn and change the potentiometer output resistance value. The monitor obtains the varying regulated gate position voltage.
Area presence sensor(Optional)
Area presence sensors use microwaves to detect if someone is operating in front of the fume hood. When there are people, the system is in the standard state and maintains the surface wind speed of the fume hood at 0.5m/s. When there is no one, it quickly switches to the standby state, and the surface wind speed is reduced to 0.3m/s.
