Venturi valve is a kind of air volume regulation and control equipment based on the Venturi effect. It is a pressure independent, high regulation ratio, fast response, high precision air volume control valve, which is widely used in all kinds of risk environment.
EB Air Control Inc. Venturi Valves utilize fast-acting electric actuators that provide a fast response (<1 second) to ensures the airflow is maintained which is critical in areas requiring a specific threshold of air flow in order to protect individuals from airborne chemicals or particulates.
EB Air Control Inc.Venturi valve series products have been successfully used in chemical laboratories, biosafety laboratories, physical and chemical laboratories, animal laboratories, GMP pharmaceutical factories, hospital isolation wards and other fields.
FEATURES
- All valves include a pressure independent assembly, factory-calibrated position controller.
- The valve can be used as a standalone device or in a fully integrated system.
- Valve controllers provide room pressurization, humidity, temperature, occupancy and emergency control.
- Precise flow control – the factory calibrated flow rate controller are executed precisely throughout its operating range.
- Self-balancing pressure independent operation – the valve maintains airflow set point by automatically compensating for static pressure fluctuations in the system.
ISO
EB AIR CONTROL INC. is registered to ISO 9001.
EB Air Control Inc. was incorporated to providing highest quality solutions, designs, develops, manufactures and markets products, systems and services to control the environment and airflow in critical spaces.
Warranty
EB Air Control Inc. guarantees all Venturi valves against defects in material and workmanship for a period of 2 years.
