Design Features of full welded forged steel ball valve

The body of ball valve is full welded,selects high quality forged material,and adopts the advanced forged forming technology to form two semi-spheres which are welded into a whole in the middle of the body.This welding technology differentiates the ball valve form others,and makes the valve more spherically,so the valve structure is more compacter,lighter and stronger.Besides,the middle direct welding realize highly accurate valve body manufacturing,makes fully and completely sealing between the seat and ball.The full welding instead of bolts completely avoids the outside leakage,so ball valve is the ideal product for under-ground,offshore working platform and under-sea equipments.

Adopting fixed plates or trunnion to support the ball

The top and bottom of the ball is supported by upper and lower fixed plates or stem and trunnion,and the ball is accurately placed in the center of the ball valve to achieve complete seals and precise movements.When plate adopted,the force exerted by the medium to the ball is distributed via the plate to the left and right bodies,so that the stem does not bear the blending moment from the medium,but only the torque from the ball rotation during the opening/closing of the valve.The low-friction PTFE Teflon composite bearings installed between the ball axis and fixed plate and between the stem and the trunnion can absorb ball moving action caused by the pressure of the medium.This structure brings stable actions and easy operations for the ball valves,and the required operation torque can be reduced,so smaller actuators can be used,and the cost is cut down.

ball valve seat is floating structure,means the seat can move along the medium direction,so that the seat can fit against the ball all the time.
Double piston effect structure seat of full welded forged steel ball valve
Seat design is special double pistons effect structure,it can ensure the seal wherever the medium flows into the ball valve.

Seat multistage seal strucute of full welded forged steel ball valve
As following graphic instruction,on seat bearing ring,set two soft sealing rings(A and B)and metal sealing spherical surface which can seal with the ball.Seat ring A is spring loaded,which seals the surface with the ball tightly to the surface to form an initial seat;When there is pressure generated from medium,the piston force is generated to make seal ring A elastically deformed and seal ring B fit the surface of the ball surface due to the piston effect caused by area difference,thus the second seal forms.When the medium pressure is rising.It will generate huge pressure to seal ring A and seal ring B,so the two seals have a greater elastic deformation,then metal seal ball surface compact with ball surface to form the third level of metal to metal seal.

Secondary seat seal device of full welded forged steel ball valve
As the above graphic instruction,the secondary seal device(seat grease injection valve)can be chosen according to the actual working condition,medium requirement,seal requirement,etc.Seat ring grease injection valve is a one-way valve,installed on the body,which can prevent the leakage and inject grease under the outside force.When secondary seal is required,there is a grease injecting channel and hole on the seat ring.The grease can form a seal between the seat and the ball,and then stop the leakage.

Q:Long story short, have a 2001 acura tl had a rough idle/ no start issue. figured out by disconnecting vaccuum from the throttle body the idle was fine with the TB pulling air through the disconnected hose port. The hose i disconnected leads to the purge valve solenoid. I removed it and it is closed (no air flow), restarted car with hose disconnected and solenoid still harnessed in (still closed). Just need more info on the function of this thing and what it should be doing.. Can i bench test it with +12V and ground on the two pins? Thanks in advance.

Q:How do you take out a valve stem?
no, the cap for the valve stem is designed to keep dirt out not hold air in ! there is a special tool that removes the valve stem, and some manufacturers have cleverly placed it on the top of the stem cap(so you would remove the cap ,turn it upside down and the metal tool will fit into the valve and unscrew the stem.), otherwise you can get one at the tire dealer or SEARS ,It's about the size of a pencil
Q:I heard alot about blow off valves making your engine run rich, but I want to get a blow off valve or bypass valve when I get a wrx. (I know some people think they're gay) but i dont care how loud it is, just want that sound. so what's the difference? I've been looking at this one:
They guy above has some of it. The reason it runs rich is because when the stock by pass valve releases the air back into the intake, it does this after the MAF sensor. Since it is getting a big surge of extra air that the MAF does not read, the ECU automatically increases fuel for a split second when the BPV releases. When you suddenly release all that air into the atmosphere, the computer does not know it and still ups the fuel. That seems like not a big deal but it runs really hot and can do things like foul up plugs and even melt the catalytic converter. There is also the issue with most aftermarket units causing stalling when you first step on the gas or even when sitting still. If you want a little noise, I would first look to getting rid of the intake silencer in the fender. It looks like a milk jug. If that's not enough, then look into an open ended intake. Just be careful with intakes as they also can cause issues depending on the brand and they rear of the car. At least an intake ca be tuned for though. The issues with a BOV can be reduced a little with tuning but can not be eliminated. Sow know that you know the risks and how it does absolutely zero to benefit the car, spend the money on something better.
Q:Ok, I recent rebuilt a set of vortec heads, but the valves I got are a bit longer than stock, I believe .1 competition products pn I2552P. I also installed howards cam 98214 springs with 10° locks and retainers, the locks are +.035. I was just wondering if I would have enough spring pressure.
I would be worried more about your geometry right now than spring pressure. Your saying the valves are .1 longer? Thats quite a bit.
Q:why is a biological valve replacement weak? in the way it does not last much longer that ten years?why do blood clots form with a mechanical valve replacement?what kind of bleeding problem can the anticoagulant medication cause?if you know the answer to any of these questions (doesnt hav to be all of them) plz answer!! thank you :p
why is a biological valve replacement weak? in the way it does not last much longer that ten years? --- Its not weak its just that it can fail like the original valve did. Most Doctors prefer to use a mechanical valve(such as titanium) because there is a lot less changes that it will fail and the surgery will have to be repeated. The St. Jude valve is one that is comonly used by doctors(thats the one I have in my heart) Mechanical valves make a ticking sound(kind of like a watch) as your heart pumps blood, this can accually be heard when your next to a person with one in a quiet place(I've freaked some pople out when they heard mine). why do blood clots form with a mechanical valve replacement? --- Blood can clot around anything that is foreign in the body, its part of the human body's natural defenses. what kind of bleeding problem can the anticoagulant medication cause? --- anticoagulants(or blood thinners) do not really cause bleeding problems as long as you have your INR monitored and controlled. those people on anticoagulants(such as Comadin) may bleed a little longer then someone not on them. a person on anticoagulants may bruise easier then someone not on them and the bruise may last a little longer. They bleed a little more but its usually not anything to worry about. A person on blood thiners may also feel colder more often due to the thin blood. Diet can also affect anticoagulents, foods such as leafy greens, alcohol, all affect these medications. Leafy Greens are high in vitaman K wich thinkens the blood. Alcohol thins your blood.
Q:I wanted to clean my 2005 accord ex 2.4 idle valve. I'm not sure where it's at any pictures or websites ? And will cleaning it make any difference
Probably won't help. Idle Air Control valves are blamed probably ten times as often as they are at fault in Honda engines. It is mounted on the side of the throttle body and has a connector with wires instead of hoses. You don't mention why you are interested in the IAC valve, but if it is because of idle hunting (revving between about 500 rpm and 1500 rpm smoothly and rhythmically), a bubble in the coolant is by far the most common cause. If the coolant is changed and not bled the normal idle speed can't get hot coolant to the Fast Idle Thermo valve (FITV) so it figures the engine is cold and the valve opens to raise the idle. That raises the coolant to the FITV, which then decides the engine is warm so the valve closes, dropping the idle speed, over and over. Burping the coolant, by opening the bleed nipple on top of one of the radiator hose housings at the engine half a turn until a steady stream of coolant comes out, should stop that. Do it with the engine cold.
Q:Hi everybody,I need some information about the operation of a double solenoid valve and how to control it using a PLC
A double solenoid has two solenoids, and when voltage is supplied to one (and not the other) the valve shifts. Note that if voltage is supplied to both solenoids at the same time, the valve will stay in the position is was in (i.e. it won't shift since the solenoids will be working against each other). This is typically not desired, so make sure you remove voltage from one side when supplying it to the other. If no voltage is supplied to either solenoid, the result will be the same as if voltage is supplied to both, in that the valve will stay in the position is was in. What this means is that the cylinder has no home position, so when power is cut, the valve will stay where it was at that time, and the cylinder will continue to do work in the direction is was working in. Again, depending upon what the cylinder was doing, this may or may not be desired. For Conrolling with PLC you may need to wire two discrete outputs of PLC to those two solenoids using relay. And the ON/OFF those two outputs as required.
Q:Im trying to replace the egr valve on a 97 lincoln continental. I need to find out what size wrench I need, to get the nut off. Do you know?
I am assuming you want to replace the EGR valve because you are getting an insufficient EGR flow trouble code. Before you replace a perfectly good valve with an inferior aftermarket part that will likely fix nothing, a little more diagnosis is in order. If you have access to a scan tool and a vacuum gauge, perform a KOER (key on engine running) test on the engine with the vacuum gauge connected to the hose to the EGR valve. When self-test reaches the EGR test, look for the vacuum guage to move during the self test. If it moves, the vacuum source and EGR solenoid are good. If not, trace the vacuum harness for leaks. Without the scanner and vacuum gauge, find a length of hose and suck on the hose, or connect to other vacuum source to test the valve. You are looking for an RPM drop at idle when you open the valve in this way. I suspect your problem is a passageway clogged with carbon. Remove the valve and throttle body to access the clogged areas and manually decarbonize. This is the most common reason for an insufficient EGR flow on a Lincoln, along with a faulty DPFE sensor or related hoses. My money is on the clogged passages or the bad DPFE sensor.
Q:I have adjusted the valve clearance twice, I still have a noise on the #2 cylinder intake. What might be causing this?
valve adjustment was not done properly or too much cam wear. These M30 engines are difficult to valve adjust. I would take it to dealer - the adjustment must be done with engine cold.
Q:Chev 350 in marine use. Made horiffic exhaust noise, especially with increasing throttle. Cam seems fine still, but the rocker on #5 exhaust was somewhat off to the side but still touching the side of the valve stem...but stem bent. What would cause this and is this the cause of the loud combustion sound (like a spark plug out of it's hole?
Do a compression check to be sure. Usually an exhaust valve will just allow to escape into exhaust. you may have other things going on, like an intake valve also. Do pressurized compression check to trace it.
