FQPV2

    • Pressure Range: Full vacuum to 150 psig
    • Accuracy/Repeatability: +/- 4%  F.S /+/- .25% F.S
    • Max Flow: 1 scfm
    • 1/4” NPT Ports

The FQPV closed-loop flow control are in a compact IP65 rated housing. The FQPV compares the command signal from the customer’s controller with feedback from the F-Series flow transducer for active closed-loop control.  The unit controls the flow of air & variety of inert gases.

These assemblies are unaffected by mounting position or vibrations to 25Gs. They operate with standard industrial air filtered to 40 microns while not consuming air in a steady state, reducing operating cost.

Minimum inlet pressure 15 psi.

FQB3

  • Pressure Range: Full vacuum to 150 psig
  • Accuracy/Repeatability: +/- 4%  F.S /+/- .25% F.S
  • Max Flow: 25 scfm
  • 1/4” to 1 1/2” NPT Ports Available

FQB3 can be used for closed loop flow control. The FQB3 compares the command signal from the customer’s controller with feedback from the F-Series flow transducer for active closed loop control. This series offers a flow monitor and control valve assembly with a < 10 ms response time.

A variety of command signals available on the FQB3. The assembly operates with standard industrial air filtered to 40 micron while not consuming air in steady state, reducing operating cost. Saturated air and lubed air will not affect performance. Optional digital display is available.

FQB2/PSR

  • Pressure Range: Full vacuum to 150 psig
  • Accuracy/Repeatability: +/- 4%  F.S /+/- .25% F.S
  • Max Flow: 250 scfm
  • 1/4” to 1 1/2” NPT Ports Available

FQB2/PSR allows for high flow closed loop flow control offering active “real time” flow control. The FQB2 compares the command signal from the customer’s controller with feedback from the F-Series flow transducer for active closed loop control. Pressure compensated model controls flow regardless of input pressure fluctuation. They can be used to repeatability control the velocity of pneumatic cylinders.

Standard industrial air quality filtered to 40 micron will not harm this controller. Saturated air and lubed air will not affect performance.
