AccuFlo Valve-Tronic™ Series

AccuFlo Valve-Tronic™ Series - Flow Controllers



The AccuFlo Valve-Tronic™ series is designed for use in highly demanding industrial applications that require accurate flow control and measurement. It can function as a stand-alone controller for basic applications or become an integral part of a process control system for automatic flow control. Temperature / Pressure compensation for real-time flow correction is standard with the AccuFlo Valve-Tronic™. This ensures the most accurate flow measurement possible.

Model AccuFlo VTO is a proven orifice design.
Model AccuFlo VTL is a high accuracy Laminar flow element with high turndown ratio up to 1:50.
