High Pressure Solenoid Valve may not close sometimes

  •   The High-Pressure Solenoid Valve may not be opened due to power outages, uneven pressure, incorrect voltage, dirt under the diaphragm, corrosion, missing components, or burned coils. However, due to too many reasons, you must try to narrow the scope of the problem to solve the problem. The most important components you must evaluate during this process are the power supply, the valve diaphragm, the diaphragm spring, the flow control adjustment, the valve inlet or outlet, and the valve discharge port.

      Sometimes the High-Pressure Solenoid Valve cannot be closed. This may be due to manual operation, pressure difference, remaining coil power, damaged armature tube, inverted or damaged valve seat, and some missing components. Be sure to thoroughly check the wiring, lead connections, components, and diaphragms to understand the specific problem. You can also try to lift the coil slightly to check if there is an electromagnetic field. If you have an upside-down diaphragm, it is wise to reinstall the item correctly before replacing it with a new diaphragm.
