// How It Works
Engineered for reliable performance.
The function of the RULA Flow Control Valve is to provide a controlled material discharge for silo and bin discharge spouts. The material flow is controlled by a V or Bell shape cut out on the rotating drum. The RULA Flow Control Valve is normally used in conjunction with the RULA Knife Gate Valve upstream for the isolation of the discharge system.
