Solenoid Valves: Three Common Issues

Posted on: 21 August 2018

If you are working on a construction project, you may be planning to install solenoid valves. This type of valve offers one significant benefit — they do not need to be manually operated by the user. Instead, this type of valve can be programmed to open and close following a preset program. However, if you are planning to install this type of valve, it is important that you understand the problems which may occur. Below is a guide to three common issues that can affect solenoid valves and lead to the need for valve repair.

Leaky valve

If you notice that fluid is leaking from the valve, you should contact a contractor and ask them to take a look at the component. The contractor will check the joints and flanges to ensure they are sealed. They will also tighten and adjust the screws in order to prevent any further leakage. If these actions to do not stop the valve from leaking, the contractor will inspect and replace the O-ring and the diaphragm.

Sticky valve

If the valve is operating but appears to get stuck in the on or off position or to open and close slowly, you will need to call in a contractor who can disassemble the valve so it can be inspected and cleaned. The leading cause of sticky valves is a buildup of material and debris within the mechanism of the component. The contractor will remove any debris and will ensure that the valve's moving parts are completely free within the required range of movement. The contractor will also check that the diaphragm within the valve is not torn or damaged as this can also cause a valve to stick.

Valve failure

If the valve stops working altogether, this first thing you need to check is that the component is still receiving electricity. The easiest way to do this is to connect a voltmeter to the wire which supplies power to the valve unit. If you do not get a reading, this suggests that the problem is elsewhere within the electrical supply system in your home and that the valve is in good condition. However, if you do get a reading, this suggests that the problem is with the with the valve itself and it will need to be removed and inspected by a contractor who specialises in solenoid valves.
