Some Knowledge of Butterfly Valve
In the 1930s, the United States invented the butterfly valve. It was introduced to Japan in the 1950s. It was generally adopted in Japan in the 1960s, and it was after the 1970s coming to China. At present, the butterfly valve above DN300 mm has gradually replaced the gate valve. Compared with th...Read more -
Key Factors to Consider When Selecting A Gate Valve
The gate valve is used as a cut-off medium, and the whole flow is straight through when fully open, and the pressure loss of the medium operation is the smallest at the time. Gate valves are generally suitable for working conditions that do not require frequent opening and closing, and keep the w...Read more -
11Types of butterfly valves and their characteristics
There are many types of butterfly valves. 1.Classified by structure (1) Centerline butterfly valve (2) Single eccentric butterfly valve (3) Double eccentric butterfly valve (4) Triple eccentric butterfly valve 2.Classified by sealing surface material (1) Soft seal butte...Read more -
The bore of the gate valves: full or reduced?
If the bore of the passage in a body is different (often smaller at the seat than at the flange connection) , this is called a reduced bore. The diameter contraction can reduce the size of the parts, reduce the force required for opening and closing, and enlarge the appl...Read more -
The Types of Gate Valve
1. According to the structure of the gate can be divided into different types. 1) Parallel gate valve: the seal face parallel to and vertical line of the center, that’s to say the two seal faces parallel to each other. In the parallel gate valve, the most common structur...Read more -
Advantages and Drawbacks to Gate Valves
Gate valve is a valve in which the wedge moves vertically along the center line of the passage. The gate valve is mainly used for cutting off in the piping system. Gate valve is a widely used valve, general with diameter larger than 50mm pipeline will be used, sometimes in small diameter pipeline...Read more -

The difference between gate, butterfly and globe valves
The gate valve is the one we see with a wedge open. When the handwheel is rotated, the wedge inside will act, thus achieving the function of opening and closing. In the butterfly valve, there is a disc that can rotate. When you turn the handle, it will start rotating. Bo...Read more -
Factors to Consider When Selecting Butterfly Valves
1.Service life: Butterfly valve in the use of more than 10,000 times, still can ensure that the closure of the"Airtight.". 2.Pressure drop: If the pressure drop is too large, it will increase the energy consumption. However, it should be noted that valves are not the o...Read more -
