Control valve booster system

Jon Lawson

ControlAir has announced the introduction of the new Type 6100 High Flow Capacity Volume Booster. 

It is a 1:1 signal to output relay that when used with a positioner/actuator, is designed to increase the stroking speed of control valves. An integral bypass valve provides system stability while allowing normal positioner airflow and normal valve actuation with small input changes. The soft valve seat design provides tight shutoff and eliminates leakage in steady state operation to reduce costly air consumption.  

Type 6100 applications include actuation of control valves used in chemical, petrochemical, oil and gas, pharmaceutical and food processing markets. Other OEM applications include printing presses, textile machinery, tyre machinery, air operated pumps, paper machinery and paint spray systems.

The High Flow Booster handles up to 250 psig (17.0 bar) supply air pressure and provides output air pressure of up to 150 psig (10.0 bar). Temperature limits are -40º to 200ºF (-40º to 93ºC). Exhaust capacity is up to 80 scfm (2,264 Nl/min) with downstream 5 psig (0.4 bar) above 20 psig (1.38 bar) setpoint. Supply pressure effect is 0.1 psig (.007 bar) for a 25 psig (1.7 bar) change. It weighs 2.5 lbs (1.13 kg). A choice of three output ports, 1/4", 1/2” or 3/4” NPT provides plumbing flexibility for easy hookup.
