QL3 Electronic High Resolution, High Flow Pressure Regulator
Price range: $1,120.00 through $1,701.00
Power cable sold separately.
The QL3 high resolution, high flow electro-pneumatic pressure regulator allows high volumes of air to move quickly and precisely.
- Unique analog PID circuit integrates error-out quickly, resulting in superior resolution
- Variable orifice solenoid avoids the pressure “steps” prevalent in most feed and bleed I/Ps
The QL3 improves and builds on the proven technology of the Proportion-Air QB3 series by using a current driven variable orifice solenoid valve and a unique analog PID circuit. This variable orifice solenoid avoids the pressure “steps” prevalent in most feed and bleed I/Ps. The combination of a step-less solenoid valve with a high-speed analog PID on a high flow volume booster allows a lot of air to be moved in a hurry, but precisely.
The output is proportional to the electrical input or command signal and an analog monitor output signal is standard.
