Q:What is a hot melt valve?
The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.
Q:What does the torque of the valve mean?
The torque of the valve is the opening moment of the valve (valve torque): Newton meter.The opening moment, also known as the operating torque, is the most important parameter for selecting the valve actuating device. Opening torque is also a measure of the quality of the valve product is another important indicator, people in the evaluation of valve quality, commonly used valve opening light, flexible to describe it. In some advanced industrial countries in the pipeline valve standards, as one of the assessment indicators, and provides manual valve opening torque is not more than 360N • M. More than this moment, it is necessary to consider the use of suitable driving devices (such as electric, pneumatic, hydraulic devices). Some manufacturers will open the torque printed in the product samples, user-friendly.
Q:Proportional valve why than other small pipeline valves
3.8 valveGraphical representation of numbers, names, symbols3.8.1 angle valve at room temperature3.8.2 cold angle valve for low temperature use3.8.3 stop valve at room temperature3.8.4 ball valve often 9 temperature3.8.5 valve at room temperature3.8.6 butterfly valve at room temperature3.8.7 check valve flow from blank triangle to non empty triangle3.8.8 pressure reducing valve, small triangle for high voltage end3.8.9 throttling valve is needle valve3.8.10 three-way valve for normal temperature use3.8.11 four way valve used at normal temperature3.8.12 safety valve spring type safety valve3.8.13 trap actual drawing, you do not have to draw arrows3.8.14 inflator, cold box, little gas huff and puff, safe useValve for normal temperature of regeneration valve of 3.8.15 reverse stop valve3.8.16 reverse loading cold angle valve
Q:Chinese valve and a valve which is better?
Look what valve you use, ah, these two can be ah!
Q:What are the major brands of valves abroad?
Fisher (Emerson's brand, pneumatic head and regulating valve is good) mountain Wu (Japan's control valve is doing well)
Q:What is the purpose of the valve?
6. Indicate and adjust the level of the liquid. Such as liquid level indicator, liquid level regulator, etc..7, other special uses. Such as temperature control valve, over-current protection, emergency shut-off valve and so on. In the above valves, the valve used to connect and cut off the medium flow in the pipeline, the use of the total number of about 80% of the total number of valves.
Q:Valve category can fill the trunk door, branch valve Mody?
Valve category can fill the trunk door, branch valve? "no, too general."
Q:How to open the gas valve with drawings
It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This one is the same as the second one, half or all
Q:What is the difference between the adjustable range of valve 50:1 and 100:1?
One is 50 times, and the other is 100 times.
Q:Valve connections - two how do different connections work?
The connection of two different connection forms is achieved by a transition conversion connector
