Bump and Hold Circuits

Imagine… a Solenoid Valve Requiring Just .13 Watts to Work!

Solenoid Solutions’ engineering team will help you a design “Bump-and-Hold” circuit that while holding valves open… can reduce power consumption by 75 to 80%. These types of energy saving circuits are designed for applications using battery power supplies where it is imperative to conserve as much energy as possible. 

The bump and hold circuit is an effective solution to improve the energy efficiency and longevity of solenoid valves while maintaining their precise control capabilities.

In these valves, the solenoid coil generates a magnetic field when an electrical current flows through it. This magnetic field is used to actuate the valve, moving its internal components to control the flow of fluid or gas. However, continuously applying a high current to the solenoid coil to keep the valve in the desired position can lead to unnecessary energy consumption and excessive heat generation, especially in applications where the valve remains in a static position for extended periods.

During the bump stage, a higher current is applied to the solenoid coil to actuate the valve quickly and ensure that it reaches the desired position. Once the valve is in the correct position, the current is reduced significantly or turned off entirely.

The hold stage requires a lower current or no current to the solenoid coil to maintain the valve in its position. The reduced current is sufficient to counteract any forces that might try to shift the valve position but is significantly lower than the initial bump current.

By using the bump and hold circuit, the solenoid valve can operate more efficiently, consuming less energy during the hold stage and generating less heat. This energy-saving feature is particularly beneficial in applications where the solenoid valve is required to remain in a static position for extended periods, such as in various industrial processes, HVAC systems, or any other application that demands energy-efficient operation.

Let’s use our already energy efficient Super Wattmizer, 2-way, normally closed valve as an example. In a Bump-and-Hold circuit, the valve requires the full .65 Watts to open. However, once the valve is open it can be powered down by 75 to 80% to an amazing .13 watts to remain open. And in the event of battery failure or lost power, the valve will automatically close.

Our experienced engineers can help you to create a power-saving “Bump-and-Hold” circuit with any of our broad range of Solenoid Valves, helping your systems become more energy efficient.
