Lug Type butterfly valves

About Product

A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and PTFE 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 ZERO leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.

Q: So I was diagnosed with a bicuspid aortic valve a couple months ago, I am 20 now and I was told that the defect normal dosent cause problems untill late 30's-40's. I have been having chest pains and at times sever palpitations. Has anyone eles gone through this? Anyone older that has experience with this problem?
I have a bicuspid aortic valve, it was discovered when I was a few days old. I'm 22 now. If you are having chest pains and palpitations you really need to get in and see a cardiologist. They'll probably give you a heart monitor which is a 24 hour thing that you wear. If you don't catch anything try asking for an even monitor, one that you wear for a month. You really do need to go see someone though. If you want to talk further about it, because I know how scary something like that can be, we can chat further on yahoo or e-mail.
Q: Can you please explain to me what an atrial valve is and what it does??
By atrial valve, I assume it meant the atrioventricular valves. Basically, in the heart, the blood flows from right atrium, right ventricle, left atrium, left ventricle. The atrioventricular valves are the tricuspid and bicuspid valves. They make sure the blood flows from the right atrium - right ventricle and left atrium - left ventricle respectively and prevents blood from flowing the wrong way in those chambers.
Q: What is the best procedure to check/adjust valve clearances? This engine is a perkins diesel inside of a cat generator. I know that he exhaust valve is .018 and the intake valve is .008.
Estoy muy apasionada de este mundo y todos mis amigos han confiado en mí a la hora de comprar un ordenador, yo siempre les he comprado de sitios web porque tienen la mejor oferta al mejor precio, pero, el ultimo ordenador que he comprado ha sido uno de juguete para mi hija, y como siempre he acertado, tiene la dimensión perfecta para ella, buenas canciones, aprende con él y imita muy bien un ordenador portátil con su ratón con todo, a ella le ha encantado muchísimo.
Q: I just got a new set of tired 2 months ago. The last 3 weeks I've had a separate tire go flat (3 in total). The last 3 the repair company said they were caused by cracked valve stems. So after the 3rd time it happened they replaced all valve stems on each tire. Now today I just got a 4th flat. That's 1 each week for the past 4 weeks. I'm taking into the shop this afternoon for them to inspect the tire. I suspect they will say it's again the valve stem. Any help on what I can do or what to say or ask to get them to fix the problem instead of just putting another bandaid on it? I'm very concerned about my safety and it really sucks that everytime i get into my car, I have to wonder, am i going to get a flat tire today...
well first go to another tire shop since when you get new tires should have got new stem with them thats pretty much Standard which tells me they are not Standard tire shop should have been new with tires should have check them all the first time shoul dhave replace them al when they put on new tires should not go back im a tire guy 35 yrs tells me they a cheap place to be getting anything dont waste your money with them anymore they cant get it right the first time second time should have three times no way dont go back
Q: in engines otto cycle
short answer more horse power.
Q: Are these valves are a kind of heart chambers pressure sensors?What is keeping them interlocked 2x2?
It's all mechanical. The valves are passive things kind of like a screen door. When you push on them from one side they open, when you push on them from the other they close. The valves are assisted by some fibers attached to the inside of the heart similar to the way a screen door is helped by a spring attached to the door frame. It's the flowing blood that pushes the valves open or closed as the heart pumps. The path that the blood follows in the heart as it beats happens to make it so that the valves close two at a time. This is because the heart is actually four separate pumps that work two at a time. There's no direct electrical connection to the SA node. The only way they're connected is that the SA node firing is what causes the heart to pump, causing the blood to force the valves open.
Q: I was told my 1995 chevy needs an idle air control valve. I know my idle is getting rougher so I may need this. What is the function of this valve and what would happen if I don't get it? Will a new valve smooth my idle? Anyone know if this valve is hard to install or not?
The IAC (Idle Air Control Valve) controls the amount of air getting into the throttle body/intake to coincide with the correct amount of fuel to get the perfect fuel/air mixture for proper combustion. Too much or too little air will affect the performance of the engine at idle. If you have the 5.7 350 v8 the idle air control valve is really an easy fix. it sits right in the throttle body and is easy to get to. Autozone in Houston, TX has them for about $22... If you don't get it your idle will be poor and the engine could possible stall at idle.
Q: hi i want to now what a BOV (blow off valve) i no what it does but i dont no the instalation process what pipes and stuff are invalved and were does it go next to the turbo of air intake
Most are designed to install on the intake/turbo piping. They're for the release of pressure surges to keep the turbo safe. Most stock bovs are not capable of raised boost which is why many buy aftermarket ones.
Q: anyone know .. if the 5.7L Hemi 2003 has a egr valve?
egr valve is easy to locate, some are electric and some are mechanical, but anyways its somewhere on the intake with a metal tube coming from the manifold to it. hard to explain, and has like to vacuum lines hooked to it.
