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?: The valve (including the valve, butterfly valve, etc.) are equipped with pneumatic actuators are standard (including restrictor valve positioner of the electromagnetic valve is connected with the installation.) is the international standard NAMUR standards, in the standard of inside electromagnetic valve is G1/4, of course, this is the solenoid valve installation in the NAMUR interface of the driver on the situation, if the solenoid valve is not installed on the drive, but through the trachea installed in a few meters away, it would have to choose a larger size, how to choose? Depends on the switching speed of the valve requirements, such as drive gas consumption is 2L, need to open in 1S, the electromagnetic the valve requires the flow of 120L/min, plus the line loss and acceleration, 500L/min is enough.

Q: I am confused as to the answer of this question. Please help.Indicate the status of the mitral, tricuspid and semilunar valves (whether they are open or closd) during the various phases of the cardiac cycle. Discuss the pressure in each of the relevant chambers or blood vessels during the phases with reference to the opening or closing of the valves.: 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: Model specification for butterfly valves: 1. classification by structure(1) Central sealed butterfly valve (2) single eccentric sealed butterfly valve (3) double eccentric sealed butterfly valve (4) three eccentric sealed butterfly valve2. by secret cover material classification(1) soft sealing butterfly valve. (2) metal hard sealing butterfly valve.3. classified by seal type(1) forced sealing butterfly valve (2) pressure sealed butterfly valve. (3) automatic sealing 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.5. classification by operating temperature(1) high temperature butterfly valve. T>450 degrees C butterfly valve (2) medium temperature butterfly valve. 120 C6. classification by connection1 pairs of clip butterfly valve2, flange butterfly valve (3) lug butterfly valve. (4) welded butterfly valve.

Q: What does the butterfly valve D361H - 25C DN350 mean?: Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM

Q: Does the pneumatic butterfly valve need electricity?: Are pneumatic, and directly rely on gas control, the most important thing is that the gas, then certainly have to take control of electricity!

Q: How to use the fire butterfly valve properly?: Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements

Q: 19 years ago i had a valve repair and now im due to have heart valve replacement. I heard that the metal valve make noise has anyone who has had the metal valve have this type f problem or any other problem with the metal valve it would be a great help if anyone could answer: Do you want to have kids or have more kids? This is going to be the biggest question you have to answer. The tissue valve will require no treatment after the replacement, other than another replacement in 10-15 years or whenever the valve starts to fail. The mechanical valve will most likely last the rest of your life, but will require the use of anticoagulants that would make any future pregnancy extremely risky. As to the sound many patients complain about hearing the valve clicking in times when it is very silent (dead of night etc.) Most find that keeping a Radio or tv on at a low level solves the problem, Id say in my experience about 50% of patients complain about hearing the clicking. The other issue is that using tissue valves, it is a slightly riskier operation every time you re-open someones chest, due to scar tissue formation. So instead of say 1-3% risk it might be 5% if the person is young and healthy. This is important since the tissue valve will only last 10 maybe 15 years. The atrial thrombus complicates matters, however which valve are they replacing? It might be possible to remove the thrombus at the same time as doing the valve. If not, mo matter what you will be taking warfarin, so the vavle choice really will not matter that much.

Q: I was wondering if someone could tell me the manufacturing date on this aircraft engine valve.: Wow Hannah! That's a cool find for sure! It appears to be possibly a valve for a radial aircraft engine as it looks very similar to ones i've seen used in Pratt+Whitney R3350's etc. It looks like it could probably date to the 1940's up thru the 1950's. Look for a Part Number stamped on the valve or on the box. After WW2 there were all kinds of manufacturers making parts for airplanes. Many were gobbled up by competitors, converted to manufacturing other products or went out of business altogether. However, a few did hang on....and I think this may be what has become of Thompson Aircraft today.... Thompson Aerospace, Inc 22431 Antonio Parkway B160-102 Rcho Sta Marg, CA 92688-2804

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: can't locate freon intake valve for 03 jaguar an was wondering were it is located at: There is no Freon intake valve for an 03 Jaguar. Freon is R12 refrigerant and the vehicle uses an R134a refrigerant system. There is also no such thing as an intake valve on any vehicle refrigerant system. There is a high pressure port and a low pressure port. To answer your question: under the hood. Any other information would likely endanger your life, since this is obviously a DIY question and you lack the knowledge to safely recharge your vehicle's refrigerant system. R134a refrigerant, if inhaled, can kill you. Do not turn a DIY project into a DIE project. Leave the complicated stuff to the professionals.
