What is the significance of choosing a low-power solenoid valve for control valves?
Thread Content
I’m a newcomer; in my work I’ve noticed that most buyers of control valves prefer to choose solenoid valves with low power consumption, even if it means paying more for them! Do low-power solenoid valves really have such great advantages? {:2_31:}
The low-power solenoid valve is an improved version: it has a higher flow rate, greater operating pressure, very low coil temperature rise, allowing for long-term operation over extended periods, and operates at a low power level. Many solenoid valve failures are caused by the coil overheating and burning out; lower power levels can prevent this
As specified by the buyer: attachment – two-way three-port solenoid valve (ASCO), 24V DC, with wiring box and manual control knob; electrical connection: 1/2 NPT； Is the reason the leader wants a low-power model just because of 24V DC? Isn’t this just the input voltage of the solenoid valve? -In summary, can it be determined whether it is a low-power device by the input voltage of the solenoid valve?
Power consumption = voltage * current. In fact, there are several types of power consumption: normal power consumption, intermediate power consumption, reduced power consumption (around 3–5 W), and low power consumption (around 2 W). Both the low-power and high-power versions operate at 24V; the distinction is made based on power consumption rather than voltage. Features of low-power operation include less heat generation; it’s okay if the voltage is slightly lower over long distances, lower power consumption, and the possibility of operating in intrinsically safe mode. The downside is its high cost and the strict requirements it has regarding the cleanliness of the air supply.
