The Award-Winning AccuValve

Delivering State‐of‐the-art Critical Air Flow Control for Laboratories, Life Science and Healthcare

The AccuValve is an electronically operated airflow control valve for critical environments such as laboratories and clean rooms. The AccuValve AV3000 is designed for 21st Century sustainability building control. The AccuValve incorporates high accuracy airflow sensing with a revolutionary design based upon proven technologies. The valve was created for sustainable "green" design, low pressure drop for energy reduction and safety through true airflow measurement.

Round AccuValve

The award winning AccuValve is designed for sustainable critical environments with very low pressure drop for energy savings and safety through true airflow measurement. The AccuValve was introduced as the first critical environments airflow control valve designed for use with electronic actuation.

Low Pressure Drop

The AccuValve incorporates a streamlined compression section and a carefully designed static regain section. These features provide lower pressure drop, lower noise level and better flow measurement conditions than all other available technologies.

True Airflow Measurement

The integral high accuracy vortex airflow sensing provides high turndown while maintaining accuracies of 5% of reading over the flow range, ensuring precise airflow control.

No Straight Run Requirements

There are no straight duct runs required before or after the valve, making application of the valve very simple. The air compression in the valve provides laminar airflow throughout the airflow range providing repeatable airflow measurement regardless of inlet or outlet conditions.

Simple Layout and Installation

All parts of the AccuValve are accessible from the front of the valve simplifying installation requirements. In addition, the actuator can be completely inverted should field conditions require such.

ASHRAE Standard 90.1 Compliant Without Additional Hardware

ASHRAE Standard 90.1 calls for the reset of the static pressure setpoint in VAV systems equipped with DDC controls. The AccuValve design allows the building automation system to provide this benefit to the owner without the requirement of any additional hardware cost. This is unique to the AccuValve for critical environments.
