The solenoid ball valve M-3SEW6U37/420MG24N9K4/V is a high-performance product widely used in the field of industrial automation control, especially in demanding fluid control systems. However, like all mechanical equipment, long-term operation or improper maintenance may cause the valve to become stuck or incompletely closed. This article will detail how to diagnose such problems and propose corresponding solutions.

First, confirm whether the electromagnet is working properly, including whether the power supply voltage meets the requirements (24VDC), whether the coil is burned, and whether the electromagnet attraction is sufficient. You can use a multimeter to measure the coil resistance and power supply voltage, and verify whether the electromagnet moves smoothly by manual operation (power off). If the electromagnet is damaged or the attraction is insufficient, replace the new electromagnet or coil and ensure that it is installed correctly.

Disassemble the valve and check whether the valve core is worn, deformed or stuck, and check whether the sealing ring is aged, damaged or blocked by foreign matter. These problems will affect the normal opening and closing of the valve. The valve body cavity and valve core need to be cleaned to remove foreign matter and sediment. If the valve core or sealing ring is damaged, it should be replaced with original accessories to ensure the sealing and smoothness of the valve body.

In addition, monitor whether the medium flowing through the valve contains impurities, such as solid particles, corrosive substances, etc., which may cause internal wear or blockage of the valve. Check the cleanliness of the fluid, install filters if necessary, and clean them regularly to reduce the damage of impurities to the valve.

Excessive switching frequency during use will also accelerate the wear of the electromagnet and mechanical parts. Evaluate whether the operating frequency exceeds the design limit of the valve. Consider adjusting the control logic to reduce unnecessary switching times, or replace it with a valve model with a more durable design.

For harsh environments, consider adding protective measures, such as using electromagnets with higher dust and water resistance levels, or improving the working environment around the valve. If necessary, professional technicians can also be invited to perform maintenance and performance verification regularly. Preventive maintenance is the most effective way to avoid failures.
