Avoid Danger When Working with Diagnostic Valves

When working with diagnostic valves, there are several “red flags” you should remember to avoid encountering a dangerous and potentially life-threatening situation.

Stick to the Specified Pressure Level

Remember that the closing force of standard actuators were designed to reach specific pressure levels. You can cause a lot of wear and tear to your diaphragm valve by operating at excessively low line pressure points. Most manufacturers, like the Hills McCanna Company, outline these types of requirements in their manuals and specifications. Review these resources before you start working with this type of equipment.

Be Mindful of Open Piping

Do not forget that reducing the spring sets can directly lead to reducing the closing force. Missing sets will overly complicate the valve closing process, which will expose you and your workers to open piping.

Even workers with limited experience know the dangers associated with open piping, especially since it is a life-or-death situation in extreme scenarios. Configure each actuator and diaphragm valve based on the manufacturer specifications about line pressure.

Clear all Pressure without Exception

Never forget to remove all pressure fully to allow the medium to escape in a timely and controlled fashion, per Valve Magazine. Without a complete removal of pressure, you will not be able to control the medium effectively – the aftermath of which could cause fatal injuries among your crew.

The general rule of thumb is to ensure all pressure is relieved completely from within your pipeline before moving anything at all. It may seem more tedious and time-consuming to do it this way, but at least you will know that you are not putting anyone’s life at risk by trying to take a shortcut.
Along with removing the pressure, take the necessary steps to collect the medium safely as well. Otherwise, you may successfully complete the job but may suffer on-site accidents and casualties along the way.
