Product Description:


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:Riding with a Schrader/Presta valve adapter?

Q:could i have a Bad EGR Valve?
you should be getting way more than that on gas mileage at least on the road anyway,a bad egr valve will cost you around 3-5 miles per gallon if its leaking and doesn't seal of when it should, i went through this with out stratus ands its 2.4.it got real bad mileage,cleaning the valve didn't help it none at all, i went to a salvage yard and got a used one off a blown engine to try it to see if that would help it and the mileage came back up on it so i replaced it with a new one,you should average about 15-17 in town with that one and around 21 or better on the highway if its running right,id try that if everything else is right and you have double checked for codes and don't get any but the egr valve you don't have anything too loose,if you have had it scanned and dont come up with any other codes it would about have to be that or really low compression on the engine causing that too happen,a weak fuel pump believe it or not will cause one to get really bad mileage and run and idle bad also,and this is often over looked as a possibility,check those things if its not them we,ll figure out whats causing it,good luck.
Q:Is a leaky heart valve considered heart disease?
Hello, Yes, it is. Obviously the leak is still within the arteries, - no blood is leaking out of the heart, - any leak is only in the backwards direction of blood-flow. One function of the valves is to stop blood which has just been pumped, from falling backwards again to where it came from. As soon as the pumping action stops, the valve has to close to lock the pumped-blood in its new forward position. If any blood leaks back through the closed valve, that is called regurgitation of blood, - and the closed valve which is leaking is described as incompetent or insufficient, in medical language. Sometimes newborn babies are born with a heart valve (or valves) that leak backwards, having not been properly formed in the womb, - or sometimes the valve (or valves) are damaged in adult life by some disease, - for example, infections like Rheumatic Fever or Syphilis, (both rare nowadays). I hope this is of some help. Best wishes, Belliger retired uk gp
Q:where are angle valves used ?

Q:Heart Valve replacement????
I'm pretty sure you've got to take a blood thinner with ANY heart valve replacement. The difference is the dosage, really. At any rate, supposedly mechanical don't wear out as easily, and doesn't get rejected as much as with the bovine or porcine valves. I would recommend he calm down a little bit, though. His worrying is only putting more stress on his heart, and if the hospital doesn't consider it enough of an emergency to schedule him immediately, I wouldn't worry so much. There have been amazing advances in cardiac surgeries, and the risks are getting smaller and smaller. Either your boyfriend or his dad's significant other should make absolute sure that he meets his surgeon, and is confident in the surgeon's abilities. If he's not confident, find another one. Good luck with it, and take care.
Q:Why would a ball float toilet valve allow air to bubble up thru the water when the tank is full?

Q:PCV valve = oil burning?
Maybe. What wt oil do you use?5w30 or 10w40? 10w40 in a 160,000 engine might also be what ya need. If ya live in an area that stays fairly hot ya might even try 20w 50 or straight 30 wt
Q:Valves Knocking?
hi, a common misconseption on this noise is the valves are banging or knocking, the noise ur hearing is actually caused by preigntion detonation, in other words, the fire is starting in the hole b4 it is supposed to, the plug has to be the one to start the fire, if there is excessive carbon build up on the piston and or valves it can devolop a hot spot and actually start the power stroke prematurally, what i would recommend is getting some type of induction service and injector clean, and i am not talking about running a can of stuff thru the gas tank, that stuff works but not good enough, try to find a shop in your area that sells BG products and get a induction service, if u cant find BG find something similiar, there product is very good. that truck and computer was designed to run on 87 octane, another thing that might be causing the knockin is the mass air flow sensor, i would take it to someone and have them look at it.
Q:Check Valve for Air Pump?
Check valve designated that it lets air go in one direction and stops water from going in reverse direction. For example if your airline gets disconnected from airpump by accident and drops on floor water won't gets syphoned out frmo tank to floor. You'd be surprised how much water can end up on floor in this scenario ;-) In order to install check valve you have to cut airline somewhat in halfs and put your checkvalve between pump and airstone. Arrow shows direction in which it passes air.
Q:86 flhtc flowed heads bigger cylinders 86 cubic 10-1 pistons keep bending valves what can i do to stop bending?
sounds like the high compression pistons dont have enuf valve relief( 2 little depressions on the top of the piston to keep the piston from smacking the valve). youll have to change brand of pistons, with more valve relief, or lower the compression ratio. next time before you completely put the heads back on, do so with out the head gasket and turn engine over by hand to see if the valves and pistons collide. (no head nuts either) if they collide, you will see the head rise up on contact. this could also be the lift and duration of the cam you are using. specifically the duration. if the valve stays open too long the piston will smack the valve that way too also at high revs, if the valve springs are weak, will cause the valve to float causing the piston to smack the valve
