Nowadays, many people buy valves directly online, which is really convenient; However, there are also some people who do not know about valves, and inquire everywhere through the Internet, and then choose a valve that is cheaper or even far lower than the average market price. When the seller delivered the goods, he found that the valve he bought was not needed on site at all; Many cheap valves not only have poor appearance, but also light weight, substandard materials, shoddy and so on.

Therefore, it is recommended that users should choose products from professional valve manufacturers whether they buy valves in the first or offline physical stores. Today, let's explain why we should choose valves manufactured by regular valve manufacturers through the requirements of valve factory testing.

1. The valve test includes the shell pressure test, seal test, and performance test adjustment test of safety valve, pressure reducing valve, and steam trap.

2. The valve should be tested according to the number of inspections determined by the relevant specifications and standards for shell pressure test and sealing test, and the valve with upper sealing structure should also be tested for upper sealing.

3. For the valve shell pressure test, upper seal test and high-pressure seal test, the test medium can choose air, inert gas, kerosene, water or non-corrosive liquid with viscosity not higher than water, and the low-pressure sealing test medium can choose air or inert gas.

4. When using water as the valve pressure test medium, it is allowed to add rust inhibitors to the water, and the chloride content in the water shall not exceed 25ppm when the pressure test is done for the austenitic stainless steel valve.

5. There are no special regulations, and the temperature of the medium used in the pressure test is 5-50.

6. Before the valve pressure test, the oil stains and dirt on the sealing surface should be removed, and it is strictly forbidden to apply anti-leakage grease on the sealing surface.

7. The pressure gauge used in the test should be verified by the relevant units and used in the cycle, the accuracy of the pressure gauge should not be lower than the grade, and the full scale value of the pressure gauge should be times of the maximum pressure to be measured. There are no less than 2 pressure gauges of the test system, which are installed at the inlet of the storage tank, equipment and the valve to be tested.

When choosing pneumatic valves, we must look at the internal structure, and different structures will be different in terms of ball valve butterfly valve matching, use process dosage, service life, etc.!

Pneumatic valves of different manufacturers are different in performance. You need to determine the requirements for the performance indicators of the valve first, and then find the right manufacturer.

In terms of valve testing methods, a series of advanced flaw detection equipment such as X-ray, ultrasonic, magnetic particle, and coloring are used for inspection in strict accordance with product quality requirements.
