How much temperature stainless steel ball valves can withstand? The Q41F stainless steel ball valve can withstand 100 to 150 degrees. The Q41H stainless steel ball valve can withstand about 500 degrees of temperature. The Q41F is a soft seal ball valve and the Q41H is a hard seal ball valve. The stainless...

1. The definition of the gate valve  It is a kind of valve widely used in the pipeline, which mainly plays the role of connecting and truncating the medium. It is not suitable for regulating the flow of the medium, but it can judge the flow size according to the height of the stem lifting (such...

Here are the common faults and solutions in the use of the ball valve.  When we install or use the ball valve, internal water leakage of the ball valve is possible. Due to frequent use of the switch, or not satisfying the requirements of the installation and other reasons, it will result in the...

The floating ball is floating. Under the action of medium pressure, the ball can produce a certain displacement. The pressure on the outlet end of the seal ring to ensure that the outlet end. The seal is a single-side forced seal. The fixed ball valve ball is fixed. After the compression does not move,...

Which has a longer service life between ball valves and globe valves? The difference between the globe valve and the ball valve is the hard seal. It can adjust the flow. The durable ball valve has a plastic seal. It can be fully opened and fully closed, but it can not be adjusted. Most iron balls are...

Here are the fire protection design of double eccentric soft seal butterfly valves. The structure of the butterfly valve is very simple. It has a small size, light weight, simple design, and simple operation. The structure principle is suitable for the production of large-diameter valves. It can better...

Here are the basic knowledge of the cast steel flanged ball valve. The ball valve is a type of valve with a ball as the opening and closing parts. With the rapid development of domestic processing technology, testing technology and intelligent control technology, as well as the continuous emergence...

Here are the usage, standard specs and construction characteristics of fixed ball valves. The fixed ball valve is suitable for all kinds of pipelines of Class150 to Class1500, PN16 to PN100, and JIS 10K to JIS 20K. It is used to cut off or connect the medium in the pipeline. When we choose different...

The butterfly valve is a valve that uses a circular butterfly plate as an opening and closing part and rotates with the stem to open, close and adjust the fluid channel. The butterfly plate of the butterfly valve is installed in the diameter direction of the pipe. In the cylindrical channel of the butterfly...

Abstract: Because of the defects of the thermal insulation ball valve in the current technical field, the sealing material and sealing structure are improved, so that the sealing performance under high-temperature conditions can be ensured, and greatly improve its service life can be improved. With...
