Q1: What is the key difference between this 2FRE10-4X/60LBK4M and the previously discussed 2FRE10-4X/50LBK4M?
A: The primary difference is the rated flow capacity. This model (60 L/min) is designed for higher flow applications compared to the 50 L/min version. It shares the same NG10 size, pressure rating (315 bar), and core features (pressure compensation, linear characteristic), but allows for controlling larger actuators or faster speeds.
Q2: What does the "B" suffix indicate in the model code?
A: The "B" indicates that this valve includes an integrated check valve. This allows for free reverse flow from port B to port A. When the proportional control is not active (or during return stroke), oil can bypass the metering orifice freely, reducing pressure drops and heat generation in the system.
Q3: What external equipment is needed to operate this valve?
A: This valve requires an external proportional amplifier (e.g., Rexroth VT-VRPA1-151-1X or VT-MRPA1 series). The valve itself contains the solenoid and position sensor. The amplifier provides the 24V DC power, processes the command signal (e.g., 0-10V), and closes the position control loop for precise spool positioning.
Q4: Does this valve maintain a constant flow if the load pressure changes?
A: Yes. The key feature of the 2FRE series is the built-in pressure compensator. It automatically adjusts to maintain a constant pressure drop across the metering orifice, ensuring the flow rate (and thus actuator speed) remains constant even if the load pressure fluctuates.
Q5: What is the "K4" electrical connection?
A: K4 refers to a specific type of individual 3-pin connector (two pins for the solenoid coil + a protective earth/PE contact). The mating connector is typically not included and must be sourced separately to wire the valve to the amplifier.
