Recently，a dyeing and printing equipment factory in Jiangsu reported to Runxin that the lifetime test results of Runxin Stainless Steel Pneumatic Ball Valves. There was no leakage after 196,000 times of opening and closing!

Test Conditions:

Medium: Tap water

Pressure: 0.5kgf/cm2

Test Frequency: Turn off for 3 seconds, turn on for 3 seconds, a cycle every 6 seconds, 14,400 times a day.

Model of Runxin Ball Valve: DN32 Ceramic Stainless Steel Pneumatic Ball Valve.

Test Start Time: February 7^th, 2021 09:30am.

Runxin's testing conditions for plastic valve bodies: Under 1.0Mpa Pressure, valve body are intact after 100,000 times of opening and closing.

Starting at 18:50 on February 17^th, It was changed to connect with the ball valve inlet with water pump, the pressure was increased to 1.6kgf/cm2, and the test was continued. As of press time, the results of the Runxin ball valve is 196,000 times without leakage! Currently, the test still on line!

Engineer Mr. Zhang, the person in charge of testing at the factory, said that the lifetime of Runxin ball valves far exceeds his expectations. Domestic stainless steel ball valve suppliers generally promise 12,000 times of closing and opening, and it is difficult to exceed 30,000 times.

At the same time, the factory also carried out the corrosion resistance tests of Runxin ceramic hard sealing ball valves, immersing alumina ball cores and silicon carbide ball core in 97% concentration of acetic acid and 94% formic acid solution.

Alumina ball core and silicon carbide ball core

Test Conditions:

Medium: 97% concentration of acetic acid and 94% formic acid solution.

Material: Alumina ball core and silicon carbide ball core

The immersion test is still in progress, and there is no change in the Runxin alumina ball core and silicon carbide ball core from the outside. Engineer Mr. Zhang, the head of testing, indicates that the test time generally takes 3 months, and Runxin will follow up the test situation and results.

Runxin ceramic hard sealing ball valve, its core components, valve core and valve seat are made of corundum ceramic or silicon carbide material, sintered at 1680℃ or 2100℃ ultra-high temperature, Rockwell hardness HRA is as high as 85°, and it is featured with light torque, good corrosion resistance and wear resistance, durability, etc., Suitable for various acids, alkalis and special media such as hydrochloric acid, sulfuric acid, sodium hydroxide, seawater, industrial wastewater, etc., it has been exported to 23 countries and regions around the world, and are widely used in seawater desalination and papermaking, printing and dyeing, electroplating, smelting, energy, chemical and medical, fluid intelligent control, cassette water meter and sewage treatment industries and so on.

Because Runxin ceramic hard sealing ball valve has the characteristic of light torque, it is easy to open and close, and the required torque of the actuator is light. Compared with other ball valve products on the market, Runxin ceramic hard sealing ball valve has a long service life and excellent performance a hundred times that of ordinary ball valves. The cost-effective advantage is undoubtedly highlighted!
