Model BV88-Digital Control Valve
Brand: Brodie InternationalThe 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.
Features- Precision flow rate and batch control
- Modular construction - all internal parts can be removed with the cylinder assembly without disturbing line connections
- No diaphragms or stuffing boxes
- 45° body design assures high capacity
- Positive shut-off
- Linear control characteristics with uniform response speed
- Automatic check valve - no reverse flow
- Fail-safe closes on loss of electrical power
- Characterized ports for better low flow response
