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:What is the working principle of the electric butterfly valve, and what's the difference between the butterfly valve and the butterfly valve?
Signal butterfly valve is generally can achieve full clearance of a valve opening electrical signal output, the general requirements of the electrical signal isPassive electric shock signals are mostly used in fire fighting systems, such as the need for valve position feedback;The electric butterfly valve is not necessarily the signal butterfly valve, because the electric butterfly valve does not have the requirement of the source contact.
Q:Who can give me a download UG butterfly valve, needle valve, diaphragm valve standard model address, Japanese standard, American Standard.
Give you the address bar, this is a three-dimensional CAD model library of an online version of the real registered mail, free of charge, there are hundreds of Chinese and foreign manufacturers of the product model is available for download, such as ABB, SMC, FESTO, AIRTAC, CAMOZZI, MISUMI etc..
Q:QUestion about Valves during cardiac cycle?
A heartbeat is a two-part pumping action that takes about a second. As blood collects in the upper chambers (the right and left atria), the heart's natural pacemaker (the SA node) sends out an electrical signal that causes the atria to contract. This contraction pushes blood through the tricuspid and mitral valves into the resting lower chambers (the right and left ventricles). This part of the two-part pumping phase (the longer of the two) is called diastole. The second part of the pumping phase begins when the ventricles are full of blood. The electrical signals from the SA node travel along a pathway of cells to the ventricles, causing them to contract. This is called systole. As the tricuspid and mitral valves shut tight to prevent a back flow of blood, the pulmonary and aortic valves are pushed open. While blood is pushed from the right ventricle into the lungs to pick up oxygen, oxygen-rich blood flows from the left ventricle to the heart and other parts of the body. After blood moves into the pulmonary artery and the aorta, the ventricles relax, and the pulmonary and aortic valves close. The lower pressure in the ventricles causes the tricuspid and mitral valves to open, and the cycle begins again. This series of contractions is repeated over and over again, increasing during times of exertion and decreasing while you are at rest. The heart normally beats about 60 to 80 times a minute when you are at rest, but this can vary. As you get older, your resting heart rate rises. Also, it is usually lower in people who are physically fit.
Q:What type of butterfly valves do you have in DN125?
125D42X: manual double eccentric flange butterfly valve 125D3 (6, 9) 42X: worm (gas, electricity) double eccentric flange butterfly valve125D41X: manual single eccentric flange butterfly valve 125D3 (6, 9) 41X: worm (gas, electricity) moving single eccentric flange butterfly valve125D43H: manual three eccentric flange butterfly valve (hard seal)125D3 (6, 9) 43H: worm (gas, electricity) move three eccentric flange butterfly valve (hard seal)125D71X manual alignment type butterfly valve125D3 (6, 9) 71X worm (gas, electricity) midline type clip butterfly valve125D3 (6, 9) 73H, worm (gas, electricity) three eccentric pair clip butterfly valve (hard seal)125BD71 (F4) X corrosion resisting fluorine (wrapped) pair clip butterfly valve
Q:What's the material of the butterfly valve seat?
Tianjin saide valve limited company can provide all kinds of valve seat material for the majority of users: white food gum X1 - X2 - X3 - Hypa EPDM rubber X4 rubber X5 - resistant rubber X6 - fluorine rubber X7 - heat resistant ethylene propylene rubber X9 silicone rubber and PTFE F4.
Q:What is the national standard for clip butterfly valves?
GB/T 12238-2008 "flange and clip connection elastic seal butterfly valve"GB/T 26144-2010 flanged and clip on steel lined fluoroplastic butterfly valvesJB/T 8527-1997 "metal sealed butterfly valve"
Q:Big block, solid lifter, valve clearances?
On solid lifters tappy is happy I don't have a manual here, but if you need to get it going now that phrase will help you.
Q:What's the difference between a clip on handle butterfly valve and a turbo butterfly valve? Where are they used?
Depending on the size of the valve and the opening and closing torque, the transmission mode is different (handle or turbine).
Q:What is the difference between turbine butterfly valve and flanged butterfly valve?
Their models are different, the structure is different, they are the main driving part, different worm gear and straight rod distinguish, all belong to the flange valve.
Q:Does the wet alarm valve group need to install the signal butterfly valve?
The wet alarm valve group shall be equipped with signal butterfly valve.The signal butterfly valve is generally installed in two parts: floor level, dry pipe, flow indicator front end, trunk pipe, wet alarm valve, front end.Floor level pipe installation is a function of the signal valve, when the floor spraying system needs repair, close the valve, open the end of the floor drain, emptying the water in the spray system, maintenance;
