You may also increase the dimensions of your pipe to reduce the speed of your liquid components. Installation of a T-piece pipe before the air can help dampen the noise and reduce the impact. Water hammering upon valve opening can be due to high liquid pressure traveling through a small pipe bore.
These errant valve sounds can be due to the difference in the inlet or outlet pressure inside the system. Erratic Valve SoundsĮvery time a valve closes or opens up, you may hear a disturbing hammering sound, or in other cases, there can be a buzzing sound heard upon the operation of solenoid valves. If ever you have an inverted diaphragm, it would be wise to refit the item correctly before replacing it with a new one. You can also try to lift the coil slightly to check if an electromagnetic field is present.
Be sure you thoroughly check your wiring, lead connections, components, and diaphragm to see what the specific issue is.
#HFS ELECTRIC SOLENOID VALVE REPAIR MANUAL#
This can be due to a manual override, pressure difference, residual coil power, damaged armature tube, inverted or damaged valve seats, and some missing components. The most important parts that you must assess in this process are the power source, valve diaphragm, diaphragm spring, flow control adjustment, valve inlet port or outlet port, and the valve bleed port. However, since there are so many causes, you must try to narrow down the problem in order to fix it. Solenoid valves may not open because of power failure, uneven pressure, wrong voltage, dirt under the diaphragm, corrosion, missing components, or a burnt coil. Here are some common problems that can occur in these parts.
