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:Can the inlet and outlet of butterfly valve be reversed? Why? What will happen if the reverse gear is installed?
Hard seal butterfly valve in any case, the reverse loading will cause tight seal.
Q:How do i use a valve spring compressor. It looks like a c-clamp, so don't tell me how to use a smaller one, but the bigger one.Thanks
The forked end goes over the valve retainer, the flat end with the screw goes against the valve face. Simply close the handle to compress the spring. You may need to adjust the width of the jaws to fit the retainer and adjust the length of the screw to compress the spring the right amount. Sometimes it helps to gently tap the edge of the retainer with a hammer to loosen the keepers before compressing the spring.
Q:I went online to check where was the pcv valve for a 2001 ford focus, but I didn't find it. Does anyone have a picture? Thanks
Its on the front of a line that looks like a big black t and it is very hard to notice.
Q:oil coming from valve into turbo charger
sounds like you need a new turbo since these vehicles dont use a pcv valve
Q:What does "D341X-16Q" mean?What do D341-16Q letters and numbers mean for butterfly valves?
D - valve type code: Butterfly valve;3 - valve drive mode code: worm gear;4 - valve connection form code: flange;1 - valve structure type code: vertical plate type;X - seat sealing surface or lining material code: rubber;16 - nominal pressure value: PN1.6MPa;Q - body material code: QT400 - 15.
Q:The difference between vertical and horizontal butterfly valves in municipal water supply
Vertical and horizontal only installation directions and installation methods are different. Functionally, there is no difference.The main difference between the two methods of installation is that:1. horizontal can effectively avoid the high temperature radiation above the pipe. The disadvantage is that it takes up a lot of space.The advantage of the 2. vertical is that the occupation space is smaller, and it is easy to install. If the pipeline is higher, it is not convenient for maintenance.
Q:For example, the arrow above is from left to right, and the direction of my current is from right to left. Is that ok? I have a diameter of 700 of the hard seal butterfly valve is so installed, but it will leak water, it will not leak, very serious
From the above example, it can be concluded that the arrow direction of the butterfly valve body refers to the direction of the pressure of the medium. Before the installation, the user must know the direction of the pressure of the valve after the valve is closed. The direction of the arrow of the free valve body is in accordance with the direction of the pressure of the medium, so that the correct use can be achieved, and the tightness of the valve body is kept in good condition.
Q:Classification of telescopic butterfly valve
2) additional torque seal butterfly valve. The seal is produced by a torque that is applied to the valve shaft(2) pressure sealed butterfly valve. The pressure is greater than the pressure on the seat or plate(3) automatic sealing butterfly valve. The pressure of the seal is automatically generated by the pressure of the medium. (1) vacuum butterfly valve. Butterfly valve with lower working pressure than standard atmosphere.(2) low pressure butterfly valve. Butterfly valve with nominal pressure PN<1.6MPa.(3) medium pressure butterfly valve. Butterfly valve with nominal pressure PN 2.5--6.4MPa.(4) high pressure butterfly valve. Nominal pressure PN is 10. 0--80.0MPa butterfly valve.(5) ultra high pressure butterfly valve. Butterfly valve with nominal pressure PN>100MPa. (1) high temperature butterfly valve. T>450 C butterfly valve
Q:16 inches below the choice of electromagnetic valve can be the same, it turned out to be DN200 election 1/4, and now there are DN350 can also use this? With it, limiter, pressure relief valve, locator model will change?
This is our company's products in Pucheng clean energy Co., Ltd. successful use case, if you need case details, you can give me a QQ number, I sent you. In addition, I suggest you add a pneumatic control valve, so that the safest, no map, I can give you. Saved is to look at the project site, if the north, the electromagnetic valve is recommended to use the 1/2 aperture, and a gas control valve or 1/4, it can guarantee the opening speed of the valve, special attention is on the use of the electromagnetic valve chain, this is very important, I will be the general experience specific issues to deal with specific, can not copy blindly, in most cases, this is no problem. And 1/4 also to see traffic, is also 1/4 solenoid valves, flow valve with big caliber is not the same, is not the same, the 1/4 path from the 2mm-12mm range, the CV value is small, about 0.1, with a large amount of 1.2, has big gap, valve opening time is also a great gap, to distinguish between the.
Q:Not the cold and hot water shut off valves. The one with a tiny handle and it looks like a T. what does it do? should I mess with it?
Hi There I installed a valve with a t-type handle for my refrigerator's ice maker. This is a saddle type valve which is place on a water line and taps into the water inlet . It has a piece of rubber around the needle valve so it will not leak. If there is no plastic or copper line protruding from the line then it should lead to an ice maker. Now I have seen the same type of valve which was placed on the water line and then hooked up to the dishwater. Either way don't mess with it unless it leaks... Why the pipe it is attached too will have to be replaced. Been there done that check out the two links below
