QC.3.3.. - 3 Way Compensated


  • Operating pressure up to 320 bar
  • Regulate flow rate from 1 to 24 lpm
  • 1 or 4 turn versions
  • Version available with lock
  • External check valve available for reverse flow applications

These compensated flow rate regulators are designed to control and maintain a constant irrespective of the pressure variations upstream and downstream of the regulation section. Their new cast construction has made it possible to obtain a wider flow rate range, taking the upper limit to 35lpm (4 turns version) while maintaining unchanged the pressure differential required to obtain good pressure compensation.
All models are available with and without reverse flow check valve, complete with an “anti-jump” device on request. This accessory has been designed to eliminate the problem which manifests itself as an “anti-jump” in the controlled actuator due to the instantaneous flow rate variation that takes place under the form of a transient every time the flow is made to pass through the regulator.
QC.3.3..3 way compensated regulator can be used whenever it is necessary to obtain a constant fluid flow irrespective of the pressure variations present upstream or downstream. It is fitted with a third T line for discharging any excessive flow rate.
When the reverse flow check valve is needed, the check valve holder type AM.3.ABU.3 can be fitted underneath the valve.
