Products Description of Swing Check Valve

Check valves are used in pipes under pressures between PN1.6~16.0MPa(Class150~2500Lb), working temperatures-196~600, They are used in industries include oil, chemistry, pharmaceutical, fertilizer, and power gene-ration to prevent the backward flux of the media.

The main structure features of Swing Check Valve:

1The products feature a reasonable structure, reliable seal, good performance and nice modeling.
2
Either soft or hard seal can be selected for the product upon different working conditions.The sealing face is built up with Co-based 
carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.
3
Small opening pressure, the disc can be opened fully with a very small pressure differential.
4
Inside-set bolt-bearing structure reduces leakage and reliable use.
5
PN≥16.0Mpa (class1500), the middle cavity uses a self-tightening sealing structure to have the sealing performance reinforced along 
with the pressure rise so as to ensure the sealing performance.
6
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:Friends,is there anyone know about LinX(Linear Exchage)Valve,how they work.thanks in advance
A valve is a device that regulates the flow of substances (either gases, fluidized solids, slurries, or liquids) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but usually are discussed separately. Valves are used in a variety of applications including industrial, military, commercial, residential, transportation. Plumbing valves are the most obvious in everyday life, but many more are used. Many valves are controlled manually with a handle attached to the valve stem. If the handle is turned a quarter of a full turn (90°) between operating positions, the valve is called a quarter-turn valve. Butterfly valves, ball valves, and plug valves are often quarter-turn valves. Valves can also be controlled by devices called actuators attached to the stem. They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure, or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water. Actuators can be used for the purposes of automatic control such as in washing machine cycles, remote control such as the use of a centralized control room, or because manual control is too difficult; for example, the valve is huge. Pneumatic actuators and hydraulic actuators need pressurized air or liquid lines to supply the actuator: an inlet line and an outlet line. Pilot valves are valves which are used to control other valves. Pilot valves in the actuator lines control the supply of air or liquid going to the actuators. The fill valve in a commode water tank is a liquid level-actuated valve. When a high water level is reached, a mechanism shuts the valve which fills the tank. In some valve designs, the pressure of the flow fluid itself or pressure difference of the flow fluid between the ports automatically controls flow through the valve. In an open valve, fluid flows in a direction from higher pressure to lower pressure.
Q:I need a bit of help. I am trying to find the location of the EGR Valve on a 1992 Chevy Cavalier 2.2L. If anyone can help me out by posting back a picture or diagram that would be great. I found all the text directions, but did not find that to be helpful.Thanks,
Egr Valve Location
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:Serious answers only please. I have a 1995 Ford F-250 XL 5.8L 351 c.i. engine. My check engine light comes on periodically when I drive. When I bought the truck a year ago the gas mileage wasn't too bad, about 9-10 mpg. I've only put about 3,000 miles on it this past year, and now the needle drops just driving it across town. I work at a Chevy dealership, and I've worked at another Chevy dealer as well as a Ford. I've always done my own work on my cars and am currently restoring a 1967 Mustang, so I have decent knowledge under the hood. I scanned the truck and it has a stored code for EGR valve voltage too high (stuck open). How bad could this be hurting my gas mileage? It's $160 for the valve and sensor even after my discount, and being a college student that's a lotta $ to pay. I'm selling the truck and need it running perfect when I do. Please, serious answers only, and help is greatly appreciated!
Get out your jumper leads and backprobe the egr solinoid. ok. 1st thing......attempt to kill the motor at idle using the egr solinoid. apply ground to the proper wire(not red) and see if the egr valve operates, killing the motor idle. if it does operate, but doesn't kill the motor......you have some cleaning to do. if it operates, and kills the motor.......the valve and solinoid are ok. (the solinoid should also vent the egr valve vacuum when de-energized) Now.....for the tricky part. AFTERMARKET EVP SENSORS SELDOM READ CORRECTLY. 1. Turn the key on and check the voltages at the Exhaust Gas Recirculation (EGR) Valve Position (EVP) Sensor. The Brown/White (BN/W) should be 5v, the Grey/Red (GY/R) is ground and must read 0.1v or less at all times. The Brown/Green (BN/GN) is the signal and MUST read 0.40v to 0.45v. If it does not, the vertical position of the sensor must be changed BY ANY MEANS NESSESARY. a NEW valve will sit higher than an old one......but sometimes not. There are things you can try to lengthen the shaft to increase the voltage reading, such as heat shrink tubing. This EVP issue is an annoying one (even for experienced mechanics), but has little effect on gas milage, unless it is TRULY stuck open. If it were stuck open.....the truck would be running very rough at idle or die.
Q:im having trouble locating the pcv valve on my 1979 oldsmobile. i have a 305 engine. i need to replace it asap, so any help would be appreciated. thanks in advance to all feedback.
Facing the engine, should be on your left valve cover. Has a hose attached to it and sticks into the valve cover.
Q:compare the structure of the tricuspid valve with that of the pulmonary valve??please help me
Pulmonary Valve Structure
Q:I was told on Tuesday that i have mitral valve prolapse and that i inherited it and that i will be fine. Well i take toporol xl 50 mg because the mitral valve prolapse makes my heart beat fast. For the past week i have noticed that my chest/lungs get tight, kind of like i have congestion in my chest, it comes and goes and sometimes its really bad and sometimes i can tolerate it. Is this normal for someone with the mitral valve condition. My cardiologist didn't go into details about the symptoms and i'm wondering if i should go see another doctor. I do have a sniffly nose and was wondering if this could be symptoms of a cold or something else. Any one out their with my condition having the same problems??? If so what is it???
Haven't had it done before but: It's a pretty involved procedure. Patient is put under general anesthesia and is usually on the cardiopulmonary bypass machine (heart-lung machine) since you can't really replace a heart valve if the heart is beating. mortality for full valve replacement according to wiki is 6-8 percent, prob less than 5% for young healthy patients. Recently, many people have been doing the procedure laparoscopically. Patients are put into the surgical ICU for typically 1-2 days after the surgery. You can be discharged about a week after. Obviously there's risks, this is a very involved and definitely not a simple procedure. However, the cardiothoracic surgeons do these procedures every day for their entire lives-they're very skilled and qualified. good luck!
Q:Someone explained on chevy that valve guide clearance can limit lift.
The measurement between the valve stem and valve guide which is the drilled machined hole in the cast iron cylinder head. .0015 - .0018 is the usual valve guide to valve stem clearance.
Q:so here are the details. i've been using my trumpet for about 6-8 years now and 1 if not 2 valves get stuck on my trumpet. the problem is not the oil as i have over oiled them too and no go. its that when i try to put my valves back in their place and twist them they don't stay in place,move ,and making either my valves stuck or making my trumpet not do a sound. what should i do? repair shop or buy a new one? i hear the clicking sound when i put them back but still all that does is either make my valve more sticky
Your first step is to clean the valves and the casings. You'll need a casing brush or soft cloth you can run through the casing to clean them. Start with warm soapy water (dish washing soap) then clean them with alcohol--if you don't have alcohol use a water with a little vinegar added. You may need to let the valves soak a bit to loosen everything up. Remove the soap and alcohol from the casings and the tubing--rinse the valves and pat them dry. Inspect them for damage, if none is found then oil the valves and re-install them. If that doesn't work take it to a shop. Don't try lapping your valves yourself.
Q:I mean dropping the valve seat. And some mechanic told me that it dropped when the catalytic converter got clogged and it hurt the engine. But the most I've heard is that if I want to avoid this from happening I should be running the engine a bit colder because the valves weren't made with the right specs and after a 100,000 miles they become a bit loose and when the engine gets to the normal temperature or just a bit above, the valve seats would drop. Does ANYONE KNOW ANYTHING ABOUT THIS?
Those old escorts ran forever. I don't fully understand your question. Are you having any problems with the engine now? If the engine is running like it always has, I think you are worrying about a stray comment from a mechanic. If one of the valves seats moves out of position, you will know. The engine will start making ticking sounds and you may lose power. If none of that is happening, you are worried about nothing. If you are having some of those issues, then take the car to a competent mechanic have the problem diagnosed and get the head rebuilt. It's not that expensive on that engine. Then you will have new valves, new seats, new guides and a very clean head.
