Q1: What is the key application advantage of the 2FRE16 size?
A: The NG16 size is designed for high-flow systems. With a rated flow of 100 L/min, it is used to control the speed of large hydraulic cylinders or motors in heavy machinery (e.g., large presses, injection molding machines, steel mill equipment), where precise speed control is required regardless of load changes.
Q2: Does this valve allow free flow in the reverse direction?
A: Yes. Unlike versions with an "M" suffix, the "B" suffix in the model code indicates an integrated check valve. This allows oil to flow freely from port B to port A (reverse flow), reducing pressure drop and heat generation during the return stroke of a cylinder, for example.
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 24V DC power, processes the command signal (e.g., 0-10V), and closes the position control loop for precise spool positioning.
Q4: What does the "100L" designation mean?
A: 100 is the rated flow capacity (100 liters per minute). L denotes a linear flow characteristic, meaning the flow rate is directly proportional to the input command signal (e.g., 50% signal ≈ 50 L/min), providing predictable and repeatable control.
Q5: What is the minimum pressure drop required for stable operation?
A: A minimum pressure differential of approximately 6 to 10 bar across the valve (inlet to outlet) is typically required for the pressure compensator to function correctly and maintain stable, accurate flow control.
