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.
