Model BV89 Two-Stage Valve

Brand: Brodie International
The Model BV89 Brodie Two-Stage Valve is normally closed and designed for precise, accurate control and shut-off of petroleum products. 

The valve controls a predetermined amount of product to guarantee smooth, positive shut-off. 

Operational functions may include low flow start-up when used with a time delay circuit or other system controls. 

The Model BV89 - Two-Stage shut-off plus pressure control achieved by sensing and controlling valve outlet pressure.
Features
  • Precision flow rate and batch control
  • Modular construction - all internal parts including seat ring 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
