Q1: What is the key difference between the 2WFCE50 and the smaller 2WFCE40?
A: The primary difference is the size and flow capacity. The 2WFCE50 (NG50) is designed for extremely high-flow systems (1500 L/min), making it suitable for massive presses, rolling mills, or marine equipment. It shares the same 420 bar pressure rating and OBE design but requires a larger ISO 7368 cavity.
Q2: Does this valve include built-in pressure compensation?
A: No. The 2WFCE50S1500L is a proportional directional/throttling valve. It does not have a built-in pressure compensator. To achieve load-independent flow control, you must install a separate pressure compensator (e.g., an FD-type pressure compensator) upstream or downstream of this valve.
Q3: What does the "24G1" suffix indicate?
A: 24G1 specifies the electrical interface:
24: 24 V DC supply voltage.
G1: Analog command input of 4–20 mA (current signal). This interface also provides a "Ready" signal output for monitoring the valve's electronic status.
Q4: What happens if power is lost or the cable breaks?
A: The valve has a fail-safe closed function. If the supply voltage fails or drops below the threshold, or if the solenoid cable breaks, the main stage spool is pushed to its seat by spring force and system pressure, blocking flow between ports A and B.
Q5: What is the purpose of the X and Y ports?
A: Port X is the pilot supply port. It must be connected to a pressurized oil source (often from port A or B, or an external source) to operate the pilot stage. Port Y is the drain port for the pilot control oil and must be connected directly to the tank with minimal backpressure.
