Review on ⚡️ Efficiently Operate with Beduan Electric Solenoid Normally Closed by Robert Wood

These DC Solenoid Valves are NOT designed for continuous duty. Continuous operation leads to overheating and failure of the coils. Power dissipation through 12 VDC Solenoid DC in steady state (12 VDC continuously applied) depends on the resistance of the solenoid to DC. Example: If the DC resistance on a 12VDC solenoid is approximately 5.0 ohms and exactly 12VDC is applied, the current will be 12/5 or 2.4A. The power dissipation is the voltage drop times the current or 12* 2.4 or 28.8 W. Such a large power dissipation will lead to overheating and failure of the coil. The manufacturer forgot to point out that this product is not designed for continuous operation. The solenoid valve can work continuously if used properly. This requires additional circuitry that controls the duty cycle of the electromagnetic relay. The solenoid needs full voltage and current to open the valve and once open the valve can remain open at a lower voltage and current. To use this valve continuously you must use an economizer device/circuit. This can be a microprocessor device or special electronic economizer devices. If your application is designed for 24/7 operation, it is best not to buy this magnet and instead find a magnet made specifically for 24/7 operation.
