Read the product brief

Flow Dynamics supplies venturi valves and airflow controls for UAE laboratory and controlled-environment projects. Selection considers the required flow range, available differential pressure, response requirements and exhaust chemistry. The valve, actuator and controls are coordinated with the room and fume-hood operating sequence.

How it works

Working principle

A mechanically pressure-independent venturi valve uses a calibrated cone and spring to compensate for duct-pressure changes within its rated operating range. The control system sets the required airflow. Valve size, response time, materials and control interfaces are selected for the laboratory duty.

Common questions

01When is a venturi valve suitable for laboratory airflow control?

Where its rated flow and pressure range, response characteristics and material construction meet the laboratory specification. Check the complete control sequence and commissioning requirements alongside the valve selection.

02Can a valve handle corrosive exhaust?

The body, lining, seals and other exposed materials must be checked against the exhaust chemistry and manufacturer’s compatibility guidance.

03What information is needed for selection?

Send the required duty, site conditions, equipment schedule and any available drawings or consultant specification. We use these to prepare an equipment selection and the supporting technical documents.
