A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and wafer type butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc  that is droved by actuators.
 

1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with no leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.

Q:How to control the single acting pneumatic butterfly valve?
Single acting pneumatic butterfly valve, Luoyang crown butterfly pneumatic butterfly valve, mainly divided into two types of normally open and normally closed. What kind of effect do you want to achieve?
Q:Read your answer, about pneumatic butterfly valve solenoid valve selection
DN200 pick 1/4DN350, DN400 corresponding solenoid valve, you can choose 3/8 hose 12mmOther accessories are related to valve path and pressure. If the same series, the valve has no change at all.
Q:anti siphon valve?
If the antisyphon valve is not leaking maybe you should focus attention on the main valve ( assuming it is a solenoid valve) to see if it closes completely. Another thing, if the irrigation zone is on an incline then the water in the system will drain to the lowest point. Sometimes it drains slowly causing the impression of a leaky feed valve.
Q:Butterfly valve D41W-1, 41, W, 1, respectively, what does that mean?
D--- stands for butterfly valves; 4--- refers to the form of flange connections; 1--- refers to the valve stem and disc in the center of the valve line, without eccentricity; w--- refers to the valve seat material and body material is the same, usually carbon steel. The final 1--- refers to the nominal pressure of 1 kg / cm2.
Q:How does the pneumatic butterfly valve control the angle of opening?
The angle of the rotating shaft is controlled so that the angle of the butterfly valve is controlled. You just have a good electrical locator
Q:What does butterfly valve do?
[1] butterfly valve is also known as turn over plate valve, is a simple structure of the control valve, but also can be used for low pressure pipe medium switch control.[2] butterfly valve: butterfly valve refers to the closure of parts (valve or butterfly plate) for the disk, around the valve shaft to achieve rotation and closing of a valve, the main cut off on the pipe and throttling role. Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation. Butterfly valve used in furnace, coal gas, natural gas, liquefied petroleum gas, city gas, hot and cold air, chemical smelting and power generation environmental protection engineering system, conveying a variety of corrosive and non corrosive media pipeline, used to adjust and cut off the media flow. Butterfly valve categories are: handle butterfly valve, turbine butterfly valve, pneumatic butterfly valve, electric butterfly valve and so on.
Q:2003 Caravan valve gasket?
the valve pan gasket won,t cause it but the fuel filter will if it,s starting to clog up and also the cat.converter !
Q:The difference between gate valve and butterfly valve, as well as cut-off valve, what are their applicable conditions? Advantages and disadvantages?
Without strict conditions and advantages and disadvantages, of course, the equipment requires a relatively high degree of automatic control. I can check it out on Baidu.
Q:How can you tell the difference between a functional valve murmur and a non-functioning valve murmur?
mechanical okorder.com/
Q:Is a valve gasket the same as a valve cover gasket?
here okorder.com/... usually you can tell when a car needs the gasket to be replaced because it will leak oil where the gasket is at the bottom of the cover i think hes ripping you off because cars usually dont need to have the valve cover replaced, just the gaskets so take it to another mechanic and get another estimate
