Model 840
Booster Pump Control Valve

Pump Control Valves protect pumps, pipelines, and other system components by isolating the pipeline from
the sudden velocity changes associated with pump starting and stopping. The “Active Check Valve” logic of
operation is a pumping-system control method that prevents the system from experiencing surges rather than
eliminating them.

The Model 840 piston actuated Booster Pump Control Valve enables
operation at high pressure pumping systems. It extends the pressure rating
range upper limit to 600 psi (40 bar).


Isolation of pump start-and-stop effects from system, for:

  • Solitary single speed pumps
  • Battery of single speed pumps (add and switch)
  • Battery of variable speed pumps (add)
