Proportion-Air - Model F-Series & FQB2 - Proportional Flow Control Valves
From Electronic Air Flow Control Valves
The FQB2 high flow control valve is a proportional compressed gas flow control assembly. The assembly consists of an FQB2-Series proportional control valve, a PSR volume booster and an F-Series high speed flow transducer. The FQB2 control valve consists of two normally closed solenoid valves, a control circuit board and an IP65 protective canister.
Details:
The FQB2 operates by comparing the user’s electronic command input signal to the signal that is returned to the FQB2 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 dome of the PSR (which causes the PSR to exhaust downstream gas) while opening the other solenoid valve adds compressed gas (to the dome of the PSR) from the supply. The volume of compressed gas on the dome of the PSR regulator sets the output flow rate. The FQB2 high flow control valve continuously monitors the user command and F-Series feedback signals to keep the assemblies flow rate at the desired point.
