Model BV28 Power Cylinder Operated Valve

Brand: Brodie International
Request Information
The Model BV28 Power Cylinder Operated Valve is designed to be used where minimum pressure drop is required or applications where it is not practical to use the flowing stream as the power medium to operate a valve. 

Because the main piston is controlled externally, and by reason of the 45° body design, pressure drop through these valves is extremely low. 

Standard power cylinders are designed to operate on 30 psi (207 kPa) minimum for full stroke and are limited to a maximum pressure of 100 psi (689 kPa). 

The power cylinder may be operated with electric pneumatic pilot valves to control application or removal of pressure from the cylinder.
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
  • Extremely low pressure drop
  • Atmospheric vent prevents mixing of line fluid and power cylinder operating fluid
