FAQ:

1. How to wire a 4WREE valve with a 4-20 mA control signal?
Connect the signal source’s positive terminal to the valve’s "IN" pin, the negative terminal to "GND", and ensure the power supply (24 V DC) is connected to "V+" and "GND".

2. What is the current consumption of 4WREE solenoid coils?
Typical current consumption is 0.8-1.2 A for 24 V DC coils and 1.6-2.4 A for 12 V DC coils (check the valve’s datasheet for exact values).

3. Are the electrical connections protected against short circuits?
Yes, integrated electronics (IPE) models include short-circuit protection, which shuts down the coil if a short is detected, preventing damage.

4. Can I use shielded cables for 4WREE valve wiring?
Shielded cables are recommended to reduce electromagnetic interference (EMI), especially in industrial environments with high electrical noise. Ground the shield at one end only.

Fluid Requirements

5. What is the recommended fluid temperature range for 4WREE valves?
Fluid temperature should be between -20°C and +60°C (-4°F to +140°F); temperatures above 60°C may accelerate seal wear and reduce fluid viscosity.
