Q:Add a valve on the trachea, when the valve behind the use of gas units,
Online search "air switch", many suppliers.You may choose your pipe according to your pipe diameter.The flow meter can also be used to control the flow of operation
Q:Where is the Shanghai valve? What brand is good?
A lot of Shanghai brand brand of Shanghai KaiWeiXi, Department of finance the Kemei high Lidun Shanghai Karon these are good
Q:How does the valve open?
Usually along the pipe is open position, you this is to turn 90 degrees, that is, open position.
Q:How many kinds of valves are there in the water pipes?
butterfly valveThe butterfly valve has the advantages of simple structure, small volume, light weight, only by a few parts. But only can rotate 90 degrees rapid hoist, simple operation, while the fluid control valves have good properties. The butterfly valve in the fully open position, the disc thickness is only when the medium flows through the power, by the valve the pressure will be very small, so it has better flow characteristics. Our company is mainly metal plastic butterfly valve, eccentric butterfly valve, butterfly valve, inlet butterfly valve, wafer butterfly valve and so on.Globe valveBall valve and plug valve is the same type of valve, only its closure is a sphere, the sphere rotates around the body center line to achieve the opening and closing the valve.

Q:What does 1/2 mean in valve specification?
1/2 inches mean, converted to metric unit is 15mm, belong to small caliber, if the valve specifications, that is, the pipe diameter is 15
Q:What does the valve QF mean?
Valve type, one of the contents, Q refers to the ball valve, F refers to the F-4 seals.
Q:Comparison of foreign valves, such as Jiang Sen, SIEMENS, Honeywell, Watts, Tyco valves?
Watts is the origin of industrial water valve, after so many years of development, the current air-conditioning, water supply and drainage, fire, general valve Liwoci is most commonly used, compared with the best foreign brands.
