Brief description of key points to consider during the installation and maintenance of the three-way ball valve

The three-way ball valve is a relatively new type of ball valve. It possesses some unique advantages inherent to its structure, such as no friction during opening and closing, less wear on the seal, and smaller opening and closing torque. This enables the reduction of the specifications of the accompanying actuator. When paired with a multi-turn electric actuator

If these 6 points are properly implemented during the design process, the lifespan of the black water regulating valve will be significantly extended!

If these 6 points are properly implemented during the design process, the lifespan of the black water regulating valve will be significantly extended!

In the coal-water slurry gasification process, the black water regulating valves in the gasifier and scrubber are indispensable components of the entire process. Due to extremely harsh working conditions, the service life of the black water regulating valves is very short, ranging from 1 month to 3 months. Therefore, it is crucial to design to extend their service life as much as possible.

What are the causes of leakage in pneumatic butterfly valves?

Pneumatic butterfly valves are used for controlling solid materials. They are often used as discharge valves at the bottom of tanks, such as the bottoms of cement tanks and stone powder tanks, for discharging materials and quickly cutting off the flow. Since most dusty materials contain particles of various sizes, the wear on the valve sealing surface is inevitable. Incorrect selection can significantly reduce

When choosing the material for the valve sealing surface, the following six factors should be taken into consideration!

When choosing the material for the valve sealing surface, the following six factors should be taken into consideration!

The sealing surface is the most critical working surface of the valve. The quality of the sealing surface directly affects the service life of the valve. The material of the sealing surface is also an important factor in ensuring the quality of the sealing surface. Therefore, when choosing the material for the valve sealing surface, the following factors should be considered:

The differences and comparisons between wave pipe stop valves and ordinary stop valves

The corrugated pipe stop valve, also known as the corrugated pipe sealing stop valve, is designed through automatic roll welding to create a metal barrier between the fluid medium and the atmosphere, ensuring zero leakage of the valve stem.

Leakage test: Incorrect operation of gate valves and globe valves

Leakage test: Incorrect operation of gate valves and globe valves

When testing the newly constructed pipeline system, the pipes and valves need to undergo preliminary tests: two leak tests, one 150% static hydraulic test, and one N2He (nitrogen, helium) leak test. The objects of these tests include not only the flanges connecting the valves and pipes, but also the valve covers and valve body interfaces, as well as all the stop valves/valve cores in the valve body.
