EFRD-G03-125-2 Dual Proportional Valve
Features
This overflow speed control valve is an energy-saving valve that can provide the necessary minimum pressure and flow for the operation of the actuator. Due to its ability to control the pump pressure based on the load pressure and keep the pressure difference to a minimum, this valve is a low energy consumption, energy-saving, and inlet throttling speed regulating valve.

Precautions for use
- Oil discharge back pressure at port Y: ≤ 2bar
- Minimum stable flow rate: 9L/min
- The pressure of the safety valve is set at the maximum flow rate, and the pressure setting of the safety valve is 20 bar higher than the upper limit of the pressure adjustment range.
- Applicable power amplifier For stable performance, it is recommended to use Northman's power amplifier, model AMP-A-2-30
