Mass flow control valve max. 10 bar, max. 850 slpm | FQB3 series
Proportion-Air
This is a compressed gas flow control assembly. The assembly consists of an FQB3 series proportional control valve and an F series high speed flow monitor. The FQB3 control valve consists of two normally closed solenoid valves, a control circuit board, a pilot operated volume boosting regulator, and a protective canister. The FQB3 operates by comparing the users electronic command input signal to the signal being returned to the FQB3 from the F Series flow monitor. The on board control circuit examines any differences between these signals and actuates the solenoid valves in response. Opening one solenoid valve removes compressed gas from the pilot operated regulators dome while opening the other solenoid valve adds compressed gas from the supply. The volume of compressed gas on the dome of the integral regulator sets the output flow rate. The FQB3 continuously monitors the user command and F Series feedback signals to keep the assemblies flow rate at the desired point.
