The Brodie International Model BV88 Digital Control Valve is designed to provide precise flow rate control and batch delivery of fluid products when used with an electronic batch control device. The valve is controlled by the electronic preset for low flow start up, high flow rate control, low flow shutdown, and final shut-off. This also provides for maximum flowmeter accuracy by maintaining a constant flow rate with varying line pressures. The Model BV88 features an external pilot control loop that consists of a normally-open solenoid pilot, a normally-closed solenoid pilot, strainer, and opening/closing speed controls.

Principle of Operation

The valve is pilot operated on a balanced piston principle. It is spring biased to a closed position. Pressure differential overcomes the force of the spring, causing the main valve to open and establish flow. The pilot control(s) vary the pressure on the spring side of the piston for position.
