How to Test Check Valves in Dubai?

Check Valves are often the most forgotten valves in the industry. However, these valves are one of the most integral parts of any system. They ensure smooth and safe operation and are found in almost all industrial plants and even homes. Testing these valves is essential to make sure they are functioning smoothly.

What are Check Valves?

These valves are also called one-way valves and are used to prevent the reverse flow of fluids and gas within the system. They come with two ports. One port is used for entry and the other for the exit. The valves are not controlled by any human or a system — and most of these valves don’t even come with any valve handle or stem.

Purpose of Check Valves

The primary purpose of a check valve is to prevent any reverse flow of liquids in the process. They work by lightening the load of the concerned water pump, preventing any overspilling, and guarding the water against getting contaminated. This makes them one of the most vital parts of any plumbing system. These valves perform a range of functions and are an essential part. Testing them becomes all the more essential. Regular tests of the valves can keep the entire plumbing system safe and allow them to function properly.

Steps to Test the Check Valves

Testing a check valve is not that tough or complicated. Just follow these three steps to perform a test.

Step 1 – To test these valves, you will have to shut off the water supply. Once the water supply is shut off, follow the supply line (you can find an arrow of the valves), keep following the line, find the valve, and switch it off. Once you are done, you must wait for at least 15 minutes for pressure to ease.

Step 2 – Search the valve for any contaminants like debris. You can do this by tapping it on the side with some tools like a screwdriver, small hammer, or a wrench. When you are tapping listen to the sound it is making — a rattling sound means the valve is fine, but if you hear a squealing sound, that can be an indication of stitch debris or a leaking valve. If you want to know the reason for the sound, then you can remove the top part of the valve and look into it to check directly. Upon looking inside, you should find a ball-in inside the valve. If you find something else, you must remove it and then out the top part of the valve back.

Step 3 – Once you are done with the above steps, you should ask someone else to help you restart the fluid supply. Start the supply for only five seconds and then switch it off. When your helper starts the water supply, put your ear and hand on the valve to check for any leakage. If the fluid is making a running sound, that indicates a leakage. When you close the water supply, you will hear a gentle click. This means the valve has closed, and water will stop running through the valve when the water supply is off.

In simple words, a pressure gauge is an equipment used to measure the pressure from a gas or a liquid. Used in several refineries, electrical, and industrial plants, these tools offer the most direct and easiest way to measure liquid and gas pressure. For 150 years, analog pressure gauges were used, but that changed around the 1970s with the introduction of the digital age. Since then, new technologies and solutions have been introduced to streamline the pressure measuring process. The new digital method offers far more advantages than its analog counterpart, and this is the reason why industries need to use digital ones for measurements.

Why is A Digital Pressure Gauge Better Than Analog One?

Pressure transducers are used by the digital pressure gauges to display the pressure readings on the digital indicator. The digital solution offers clear readability and fast results, which is based on the settings the user inputs before taking the measurements. The digital pressure gauges are primarily powered by solar power or batteries. This solution offers consistent reading and is more reliable than analog pressure gauges. Several characteristics make digital gauges better, and some of them include:
  • Durability One of the best features of digital ones is they can perform seamlessly in extreme temperatures, in areas with heavy vibrations, and even hazardous conditions without failure. A digital pressure gauge is designed to withstand cracking and even abuse. Typically built from strong materials like stainless steel or aluminum makes them more durable than analog ones. These pressure gauges also have a face made from crack-resistant plastic, which further protects them from flying debris, shock, and hazardous chemicals.
  • Customization Options You can customize your digital pressure gauges according to your specific requirements by either adding or removing some features in the engineering unit. Certain digital gauges can even create customized units, which will allow the pressure to be displayed in force or torque units. Doing the same thing with an analog pressure gauge is nearly impossible. Several digital ones also record the high and low reading automatically; this makes referencing them in critical situations much simpler. Also, data collection is one of the most notable advantages of digital pressure gauges. The hydraulic ones can send the collected data to a computer, data logger, or any other specified instrument for better analysis.
  • Calibration Keeping an analog pressure gauge calibrated is a massive task. However, once you have calibrated the digital pressure gauge, it will remain calibrated much more reliably. Also, in digital ones, the calibration is done using software, hence it will be much more accurate and precise.
  • Readability The digital pressure gauge always features a large and easy-to-read display. These displays are often supported by a bright backlight, and taking a reading from these digital gauges is easy. However, reading from analog ones requires interpreting the location of the needle. Misreading due to parallax error is frequent with analog gauges, depending on the angle of the person who is converting the data, the dial can appear to be in several different directions. This can increase the chances of mistakes, and the accuracy of data can be compromised as well. Since the digital pressure gauges display a numerical value of pressure, there will be no parallax error.
