Steps In Maintaining A Solenoid Valve

In most cases, dismantling machinery for other service may be an opportune time to finalize solenoid valve maintenance. A hands-on management can bring about the best likely performance of the valve control and the system as a whole.


Good and practical maintenance of a solenoid valve can make its life longer and guarantee expected functioning. Maintenance of control valves despite it being a tiny component may possibly be valuable in the long run and what looking after can yield to the whole system. To find out when best to examine this type of valve controls, take into account the benefit of a valve breakdown at a favorable time; the risk of probable injury in case of a failure; the monetary expense of a badly timed valve breakdown; the financial loss considering productivity and work outcome when a valve fails to function; and service expense having to do with time and energy. In most cases, dismantling machinery for other service may be an opportune time to finalize solenoid valve maintenance. A hands-on management can bring about the best likely performance of the valve control and the system as a whole, including a long product life.


This is a 3 Way Directional Solenoid Valve. Steps in maintaining a solenoid valve consider the following:


  1. Consider safety prior to repairing a valve by disengaging the power source and reducing the pressure of the system. Safe operation of the component based on the fluid regulated within must at all times be considered.

  2. Check the coil for any crevice in its covering. Moisture can get into the coil and affect the performance of the solenoid valve. Coil connections ought to be looked into as well for breakage or deterioration. Make sure that the coil fits properly on the stem of the valve before powering it up. The consequent current flow will cause for the coil to burn out.

  3. As the coil is taken out, the pressure vessel emerges. The stem of the valve may be taken out by a wrench. Clamping it may depress or twist the tube. The interior parts of the valve operator such as the plunger with a seal, plunger return spring, O-ring, sleeve, and operator body have to be inspected for signs of deterioration or damage and replaced if necessary. Replace worn out or damaged parts of a solenoid valve as necessary.

  4. Consider inspecting the seals that may distend, have cracks, or have been damaged. Check the springs if worn, coils if broken, body orifice may be scratched, and the crest may be damaged. The plunger would need inspection for wear as well because whenever it is raised, it usually touches the sides and the topmost part of the sleeve.
