Product Overview of Signal Feedback Solenoid Valves

Signal feedback solenoid valves are a new type of solenoid valve developed for remote automatic control, enabling real-time monitoring of the valve's normal operating status. Equipped with an integrated signal feedback device, they are automatically controlled by the PLC system. Each on-off operation of the solenoid valve sends a power signal feedback to the PLC system, which monitors the valve's operating status: when the valve is open, the signal common wire is connected to the open signal wire; when the valve is closed, the signal common wire is connected to the close signal wire. This valve features the function of judging whether it is open or closed, and can be used long-term in remote-controlled automation fields.

Key Features of Signal Feedback Solenoid Valves

Capable of judging the valve's on/off status.

Adopts embedded sealing materials, with a service life ten times that of similar products.

Processed by CNC machine tools, ensuring the accuracy and reliability of the solenoid valve.

Equipped with a special plastic-sealed coil, improving the valve's reliability and providing waterproof and moisture-proof performance.

Compatible with liquids, gases, and oils, expanding the valve's application range.

Flexible on-site installation; fast response speed; valve body manufactured via hot forging process, featuring an aesthetic appearance.
