Product Description:

PTFE 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:I cant find the EGR Valve on my 2003 dodge ram 1500 5.7L Hemi DOES IT HAVE ONE?
it might be on the passenger side on the valve cover
Q:wheres the egr valve?
okay your gonna look at your intake manifold. Then locate where your air intake connects to the throttle body. Look around the throttle body and you should see the egr valve it will be hidden by your air intake but if you look hard enough you'll find it and also if you see in vacuum lines running around there, they will point you in the right direction because your egr valve has two vacuum lines that run to it. hopefully that helps.
Q:Reed valves?
Reed valves were popular when you could get a street two-stroke bike. They allowed air to flow only one-way. I think Yamaha even had a nifty rotary valve thing that squeezed the air that the piston sucked so it would flow a bit faster into the combustion chamber. With a four-stroke, I don't think there's any advantage to complicating the air flow with a reed. That's what cams and valves do. You need to burn more fuel to get more power. There are several ways to do this. You can do this with more RPMs, more fuel/air mixture, or a larger displacement. But that's about power, not necessarily a reed valve.
Q:Valve adjustment on my 1994 Honda civic ex?
a valve adjustment is where the valves are put back into spec, they have a certain amount of space from the rocker to the valve stem, to accommodate for heat expansion every so often that clearance needs to be readjusted, otherwise the rockers can get too close and start to tap typically my friend charges $60 at his shop.
Q:Question about bicuspid valve...?
Yes, some studies have found Bicuspid aortic valve to be hereditary. Some studies show that the incidence of bicuspid aortic valve can be as high as 5% in families affected with the valve issues. In the UK there is no routine screening for people with relatives who have BAV. If you develop any symptoms or problems then of course see your GP again.
Q:Does having a Torque Valve on a 2 stroke dirtbike give much more power?
It's probably referred to as a Torque Valve in the spare parts manual. But yes, the power valve is what gives the WR250 it's buzz. Hook it up!
Q:a valve-job question?
MOST modern engines have hydraulic lifters, which pretty much eliminates the need to have any periodic valve adjustments. You can take stock heads to a shop and put two grand into them and make better flow and bigger valves and more power, or actually buy a set of performance heads for less and make more power. the only time your valves would need to be set is when putting together a new engine, or taking apart the one you have and replacing say a head gasket or something. (in which case you would have a shop go through the heads and make sure they are up to factory specs. If your engine is running fine, and you have kept the oil clean and the motor in good tune, follow the recommended maintenance intervals in your owners manual. a valve adjustment is not going to give you horsepower.
Q:Heart valve surgery!!!!!!?
It depends a lot on which valve and why it's being replaced, but unless the COPD is very bad, the average chance that a 58yo man who does not have any other major medical problems will survive single-valve replacement surgery is better than 98% if the surgery is done by an experienced surgeon at a good hospital. The COPD will very likely mean that his post-operative recovery will be prolonged and difficult, but he should do fine.
Q:what is a car valve?????
valve A way to turn on or a off of anything Liquid or gas or air works same as a switch does for power it controls flow of
Q:99 Eclipse Valve Cover?
You can have it dipped in chrome and detailed for the lettering. It pricey but its the best way or you could try finding chrome spray paint that is good up to 500 degrees and do it yourself but it may not look as good.
