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:

1、The 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: And why is it so expensive?So after many months of trying to figure out why my 93 Mercury Cougar V6 has been breaking down chronically, I was recently told it needed a valve job. At 21 years old and just over 83k, l suppose that's the big issue.What exactly is replaced/fixed with a valve job? Will my car run like new AND STAY THAT WAY? Thanks :): a vale job is nothing it means nothing you dont get a valve job you get new heads... are rarely do they cause actual not functioning of the car. you have an old car that has seen better days. and age is catching up to it. the car itself is not the best made car and at best im surprised it hasnt hit the junk pile yet.

Q: so do v-6 engines mean 6 cylinders right?, but what are valves? sometimes they are like double the cylinders (12 valve v6). what do they do, and cars that have like 2.5L does that mean how much fuel is injected and does more mean more power?on a side note, what kind of engine is the evo x? is it 4 cylinder? but has really good technology in it and is that how it has such high bhp?also if anyone knows, i kinda know what torque is but can someone explain in laymen terms? does more=better?: Yes v6 means 6 cylinders (pistons). Each pistons need to have gas come in and out and so the valves open and close to do exactly that (breath). There are at least 2 valves per piston - one (set) for exhaust and another for intake. Sometime to make it breath easier, there are 2 valves on each set. The 2.5L mean 2.5 liters (the measurement of the pistons) or basically the engine. The larger the displacement the more powerful (theoretically). Of course the larger the displacement the more fuel need to be injected. The exception is TURBO charged engines which stuff extra air (and extra fuel) so even a small engine take more fuel than equal non-turbo engie. The Evo uses much more than high tech engine to be that good. Besides being powerful, it uses the computer to divide the power to all 4 wheels in such a way to keep the car pulling even in a hard turn. === The TORQUE is the actual measure of engine power. The horse power is a translation of torque into something that people understand (horse - power). Good Luck...

Q: I live in Houston (where it hardly EVER freezes during the winter..) This winter it froze and the valve on the sprinkler system flew off and water started shooting straight up. Now that it's getting warmer and I'm going to need the sprinkler.. I have to repair it. Is this an easy fix that I can do myself? Or should I call someone.: Yes easy fix-- go to your big box store with the old valve-- so you get the right size and buy a new one less than $ 40.. chances are with the freeze the plastic parts cracked when the water inside froze---

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...: Any reputable tire shop will install new valve stems when mounting new tires. This really sounds like somebody is messin with you. Anyone else in your area having similar problems?

Q: i wanted to know what is the actual difference between check valve (non return valve) and globe valve?: Check valve/non-return valves are unidirectional, meaning flow can only go through them one direction. Check/Non-return valves usually don't include any kind of manual actuation. Globe valves have a sphere with a hole cut through it, as the globe is rotated within the housing, the hole aligns with the valve inlet and outlet, or is sealed from the inlet/outlet by the valve casing. Thus, the handle/knob is used to rotate the ball, thereby opening or closing the valve. Because the hole is cut cleanly through the ball, flow through a globe valve is bi-directional.

Q: I really like the sound that a blow-off valve makes when they are in audi tts. So I was wondering if I got one for my '02 225hp Audi tt if it would damage the engine in any way. I have read that diverter valves are better, but I want the sound of the blow-off valve. Also any recommendations on blow-off/diverter valves would be great.: Well, in the audi system it expects to get the extra boost back from the diverter valve so it would be against your best interest to blow off all the boost. However, they do make blow off valves that sound great but only lose 10-30% of the boost which would have little to no effect on the car and you still get that cool sound. I personally am not into blow off valves so I've never bought one but I've heard some good things about Forge blow off valves and I believe they make a 30% blow off like what you would want.

Q: Hey I'm high rite now and i have a checkup for mitro-valve prolapse tomrow, i was wondering if they will take my blood and see THC in me....: Mitral valve prolapse exams look more anatomically than physiologically. Meaning, they will take a picture of your heart instead of looking at the chemicals in your blood. BUT a prolapse may mean that your blood does not have enough oxygen in it because your heart circulation is abnormal, they may take a blood sample to test the level of oxygenated blood relative to deoxygenated blood to check this.

Q: I have the correct tools and have done this before. All I want to do is change all three valves that operate the water (hot,diverter,cold). The shower is leaking. I want to change all three valves to stop the leak. I will call a plumber if I can't change the valves or stop the leak. Please tell me what tools I need and I'll begin from there. I have three handles/valves in the shower(cold,diverter,hot).The cold is here # and the diverter is in the center which is here # and the hot is here #. They all line up like this c# diverter# h#. These are how the valves are set up # # #.: There is not three separate valves, it is basically a manifold with two shut off valves and a mixing valve all combined into one unit. Replacing the whole unit would be the easiest most efficient thing to do. What I'm thinking has happened is that the valves started to leak, and you kept tightening the handles in an effort to stop the flow, thereby stripping the handles, not the valves. Get a faucet handle puller, pull the handles, and remove the valve stems by undoing the packing nuts, there is also a seat reamer tool, resurface the seats and install new washers, buy new handles and you may not have to replace the whole diverter assembly. It will take more time but will be cheaper also.

Q: I was getting something to burn and smoke up this empty 2 liter bottle for my friend's brother's science experiment. We didn't find any wood, so I took his trumpet valve oil, dripped some on a piece of wood that wouldn't burn and make it smoke up. Does burning valve oil have any negative side effects as opposed to say, regular oil? I shouldn't have been so lazy and just used vegetable oil or something haha....: Valve oil is basically just mineral oil and various other ingredients. You can buy pure oil, and it's also the main ingredient in baby oil and other medicines. Nothing wrong with burning it.

Q: How come my boiler supply valve isnt letting water into my boiler, i have a cold water supply hooked up to it with the valve on i have tested the copper pipe goin into it and water flows into it, but when It reaches the valve it stops. I understand that it my have a backflow preventer in it and I am wondering if that could be malfunctioning. The hole you see on the front is where my expansion tank screws in. Also where could I get a new Valve. Thanks.http://img149.imageshack.us/i/boilerfillvalve.jpg/: I work on antique steam boilers and engines for a hobby and if your supply valve isn't letting feedwater into the boiler, I'm going to tell you right now that you potentially have a VERY dangerous situation on your hands. Until you get this issue resolved, I would recommend that you not steam this boiler up under any circumstances, unless you have a backup feedwater delivery system that is working correctly. Many people don't know this, but a low water condition in a boiler under steam is essentially a ticking time bomb and can result in a fatal explosion. As to what may be causing it, I would say it's possibly one of two things: 1.) The check valve has been installed backwards and the flow of water is basically pushing it shut. 2.) The check valve is installed correctly, but is frozen shut due to corrosion and scale. Either way, I would have a certified boiler inspector come out and take a look at it; he can probably tell you more than I can.
