BV70 Differential Control Valve

Test Product

The BV70 Brodie Differential Control Valves are normally closed valves designed to maintain a controlled pressure differential within +/-2%.

Features include

  • The Valve is pilot operated and operates on a balanced piston principle, 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 varies the pressure on the spring side of the piston for position.
  • The pilot is balanced, single seated with large ports and will operate on a differential as low as 5 PSI (34.5 kPa).
  • The Brodie Model BV70 is recommended for applications requiring valve closure on decreasing pressure differential, such as, pump differential control, LPG or Anhydrous Ammonia vapor control.
  • The “AP” option valve cylinder incorporates a combination of seals and o-ring materials to provide optimum performance in aggressive product applications. Specify “AP” Option at time of order when valve is to be used on products which may affect standard seals.
