What Is a Zero-Power Pulse Solenoid Valve?

Many engineers come across a term during product selection — the “Zero-Power Solenoid Valve,” formally known as the Zero-Power Integrated Reset-Type Latching Solenoid Valve. What exactly is it, and how does it differ from common solenoid valves?

Starting with Traditional Solenoid Valves

• Traditional monostable solenoid valves: These rely on continuous power to hold the valve open or closed. Long-term energization means ongoing power consumption, heat buildup, and reduced service life. However, they are very simple to apply.

• Conventional bistable (latching) solenoid valves: These switch states via a short pulse and consume no power while holding a state, making them highly energy-efficient. However, they require a dedicated pulse controller, which itself must remain powered at all times. Wiring and commissioning are also relatively complex, and there is a risk of mis-operation. Deployment requires specialized supporting equipment and expertise.

The Approach Behind Zero-Power Integrated Reset-Type Latching Solenoid Valves

This type of product combines the advantages of both:

• Standard universal wiring: Can be wired and used directly as a conventional monostable valve, with no need for an additional pulse controller.

• Zero power while latched: Once energized to latch, the valve enters a holding phase with extremely low power draw (DC < 0.05W, AC < 0.06W), generating no heat throughout, and delivering overall energy savings of more than 90%.

• Automatic reset on power loss: When the device is fully de-energized, the valve automatically resets, solving the long-standing industry problem of conventional latching valves being unable to reset without power.

• Built-in integrated drive: Features a BMC one-piece housing and a standard DIN43650 interface, making it plug-and-play with no need for additional drive accessories.

Suitable Applications

Because it is compatible with conventional monostable wiring and application logic, while also offering the ultra-low power advantage of bistable valves, this type of solenoid valve is especially well suited to:

• Industrial control applications requiring continuous power, where energy-saving retrofits are a priority;

• Battery-powered, low-voltage IoT devices where battery life is critical;

• Gas systems, building automation, fire protection, agricultural irrigation, and other scenarios with high requirements for stability and safety.

In short, the Zero-Power Integrated Reset-Type Latching Solenoid Valve is a solution that lets engineers keep their existing wiring and avoid adding a pulse controller, while still gaining both “ultra-low power consumption” and “automatic reset on power loss” in one device.
