Sanitary grade quick release solenoid valves and sanitary grade clamp solenoid valves refer to valve fittings used in pharmaceutical, food, and other industries with high hygiene requirements. The valve body materials used are 304 stainless steel and 316 stainless steel. Sanitary grade stainless steel solenoid valves are mainly sealed with silicone rubber and polytetrafluoroethylene, and are commonly used in pharmaceutical or food factories for maintenance and configuration of related equipment and pipelines.

Overview of signal feedback solenoid valve:

The solenoid valve with signal feedback function is an industrial equipment controlled by electromagnetism, which is used to adjust the direction, flow, speed and other parameters of the medium in the industrial control system. The signal feedback solenoid valve is based on the valve itself integrating a signal feedback device, which is automatically controlled by the PLC system. When the solenoid valve is opened and closed, a power signal is fed back to the PLC system to monitor the operating status of the solenoid valve. Signal solenoid valves can be used in conjunction with different circuits to achieve the desired control, while ensuring the accuracy and flexibility of the control. Function of electromagnetic valve with signal function: The electromagnetic valve with signal function adopts a pilot piston structure and stable performance; Good sealing and quick switching; Autocratic coil, not easy to burn; The coil has low power consumption and long lifespan; Has the function of judging whether the valve is open or closed; The most suitable for use in explosive hazardous areas. Electromagnetic valves with signal function are the preferred products for automation control engineering, project renovation, and equipment matching; The most suitable automated pipeline system for detecting whether the medium is flowing.

Working principle of solenoid valve with signal feedback:

Normally closed: When the coil is energized, the electromagnetic core is attracted, the pressure relief hole is opened, and the main piston is pushed by the medium pressure to open the main valve port, allowing the medium to flow. When the coil is powered off, the main valve port closes and the medium is cut off. Normally open: When the coil is energized, the electromagnetic core is attracted, the pressure relief hole is closed, the main piston is pushed by the medium pressure, the main valve port is closed, and the medium is cut off. When the coil is powered off, the main valve port opens and the medium flows. Signal feedback: (With this function, the temperature of the valve contact does not exceed 100 ℃). When the valve is opened, the signal common line and the open signal line are connected. When the valve is closed, the signal common line and the closing signal line are connected. Features of electromagnetic valve with signal feedback function: 1. Free installation on site; The action responds quickly. 2. The valve body adopts hot forging process and has a beautiful appearance. 3. Pilot operated piston structure, stable performance, and fast switching. 4. Using original sealing materials, the lifespan is ten times that of similar products. 5. CNC machining ensures the accuracy and reliability of solenoid valves. 6. By using specialized plastic sealed coils, the reliability of the valve is improved and it can be waterproof and moisture-proof. 7. Liquids, gases, and oils can be mixed and used to increase the range of valve applications.
