Frequently Asked Questions
What is the main difference between this model and the A1 version?
The key difference is the control signal type. This model (F1 version) uses a 4-20 mA current signal for pressure control, while the A1 version uses a 0-10 V voltage signal. Both provide proportional pressure control, but the 4-20 mA signal is often preferred in industrial applications for its better noise immunity and longer transmission distance capability. The electrical interface, power supply, and other mechanical specifications remain identical between the two versions.
What does the "F1" code in the model number indicate?
The "F1" code specifies the electrical interface type. In this model, "F1" indicates that the valve accepts a 4-20 mA analog current signal for pressure control. This is a standard industrial signal type that provides proportional control of the pressure setting. The valve converts this current signal into the corresponding pressure value within its operating range (up to 80 bar in this model).
What are the wiring requirements for the 4-20 mA signal?
The 4-20 mA signal requires a 2-wire connection through the M12 connector (K31 type). The standard pin assignment typically includes: signal input (4-20 mA current loop), power supply (24V DC), and ground/return. The internal resistance for the current loop is typically around 250 Ω. It's important to ensure proper shielding and grounding of the signal cables to minimize electrical noise interference, especially in industrial environments.
Can this valve be used in systems that previously used 0-10V control?
Yes, but it requires signal conversion. If your control system outputs a 0-10V signal, you would need an external signal converter to change the 0-10V voltage signal to a 4-20 mA current signal. Many industrial controllers and PLCs can be configured to output either signal type, so check if your control system can be switched to 4-20 mA output mode before considering external conversion.
What are the advantages of using 4-20 mA over 0-10V?
The 4-20 mA signal offers several benefits: better noise immunity (current signals are less susceptible to electrical noise and voltage drops over long distances), longer transmission distance (can transmit signals over hundreds of meters without significant signal degradation), live zero detection (the 4 mA "live zero" allows detection of broken wires or signal loss), and industry standard (widely used in process control and industrial automation).
