Application range of electromagnetic reversing valve

The electromagnetic reversing valve is the core element that realizes fluid direction control in hydraulic and pneumatic systems. It drives the valve core movement through electromagnetic force to change the on-off or flow direction of the fluid channel. Its application range is wide, covering many fields such as industrial automation, engineering machinery, agricultural machinery, transportation, etc. The following are the specific application scenarios and features:

Advantages: Adapt to extreme temperatures (-40℃ to +120℃) and humidity environments.

Sewage treatment and garbage disposal applications: switch hydraulic or pneumatic systems, control valve opening and closing, equipment driving, etc.

Advantages: Corrosion-resistant design, adapted to harsh media environments.

6. Precautions for selection and application

Parameter matching flow rate and pressure: Select the diameter (such as 10mm to 32mm) and pressure level according to system requirements.

Electrical parameters: Confirm whether the voltage (such as DC24V/AC220V) matches the power.

Environmental adaptability temperature and medium: Select sealing materials (such as NBR, FKM) according to the operating temperature (-40℃ to +120℃) and medium type (mineral oil, water-based hydraulic oil).

Installation and maintenance installation direction: Pay attention to the installation direction of the oil port and the electrical interface to avoid misoperation.

Maintenance cycle: Regularly replace seals and lubricating oil to extend service life.

7. Typical cases

Case 1: Injection mold clamping control requirements: high voltage (28MPa), large flow (1100L/min), fast response (≤50ms).

Solution: 4WEH series solenoid reversing valve is adopted to achieve efficient switching between mold clamping and mold opening.

Case 2: Excavator walking control requirements: adapt to the wild environment (IP65 protection), vibration resistance (5-2000Hz vibration test), long life (≥1 million commutation times).

Solution: Use an electromagnetic reversing valve with damper to reduce reversing impact and extend the valve body life.

8. Summary

With its advantages of fast response, accurate control, and adapting to harsh working conditions, the electromagnetic reversing valve has become the core component of the fluid control system. Its application scope covers multiple fields such as industry, agriculture, transportation, and energy, providing guarantees for the efficient operation of various mechanical equipment.
