FAQ:
Q1: What is the main purpose of this 2FRE valve?
A: This is a high-performance, electrically controlled flow control valve. Its primary function is to provide precise speed control for hydraulic actuators (cylinders or motors). The key feature is that its flow setting remains constant even if the system pressure changes, ensuring consistent actuator speed regardless of the load.
Q2: How is this 2FRE valve different from a standard throttle or Z2FS valve?
A: The critical difference is pressure compensation. A standard throttle valve's flow changes with pressure fluctuations. The 2FRE valve has an internal pressure compensator that automatically adjusts to maintain a constant flow rate for a given electrical signal, providing much more accurate and repeatable speed control. It also allows for electronic, on-the-fly adjustment via a control signal.
Q3: What do the codes "B" and "16Q" in the model number mean?
A:
B: Specifies the type of pressure compensator. Version "B" is a standard compensator without an external pilot control function for closing.
16Q: 16 is the rated flow in liters per minute (16 L/min). Q indicates a progressive flow characteristic, meaning the flow increases progressively with the control signal, allowing for finer resolution at lower flow rates.
Q4: The designation includes "MV". What does the "M" signify?
A: The suffix "M" indicates that the valve does NOT have an integrated check valve. Therefore, it regulates flow in only one direction (from port A to B, as per the flow direction arrow on the valve). Flow in the reverse direction is blocked. A version with a "V" instead of "M" would include a free-flow check valve for the reverse direction.
Q5: What components are needed to operate this valve?
A: Unlike valves with onboard electronics (OBE), this valve requires an external proportional amplifier. You need:
A compatible amplifier card (e.g., Rexroth VT-VRPD-1-1X).
A command signal (e.g., 0-10V, 4-20mA) from a PLC or controller.
A 24V DC power supply for the amplifier.
The valve's integrated inductive position transducer provides closed-loop feedback to the amplifier for precise spool positioning.
