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.
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.
Small opening pressure, the disc can be opened fully with a very small pressure differential.
Inside-set bolt-bearing structure reduces leakage and reliable use.
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.
Different parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.

Q:Burnt Valve in Ford 302 EFI?
You will need a head rebuild kit: valves, valve seats, valve guides and all the seals and gaskets. You will need a valley pan gasket. Leave it to the machine shop to get all the parts that go in the head. I left out valve springs and spacers that may be worn out of spec. If you ever pulled and replaced heads, you have a good idea what you're in for. If this is your first time, get help from someone with experience so you don't end up with a basket case needing to be towed to a shop for assembly. That's a nice engine and you shouldn't try to play cheap fixing it.
Q:PVC Ball Valve air rifle questions.?
These bike tire valves are called schrader valves i got mine from a car repair shop where they like had them for free. I mounted it into a pvc pipe by drilling a hole just big enough for the stem but there was a ball at the end that keeps it from falling out. Then to seal it you could you gorilla glue or epoxy to make it air tight
Q:what is the reason why non-return valves are installed in the discharge lines of the sea water pumps? ?
..?..non-return valves..? I will assume that your 'non-return valves', are what is also known as check valves. Check valves allows flow in one direction only. These are used wherever you need to prevent backflow into the system, or to maintain a charged circuit with fluid, until you choose to unload(depressurize ) it. Now, why are they used in discharged lines of salt water, basically to prevent backflow....reason not known, here , requires usage info.
Q:where are angle valves used ?

Q:92 F150 Fuel tank selector valve?
There is no selector valve on 1992-95 F150's. There were or the older carbureted trucks but newer ones are all fuel injected and have in-tank fuel pumps. The switch on the dash just selects which pump you turn on. I'd say the front tank fuel pump has gone bad or possibly has a cheaper electrical problem (if you're lucky). Exact same thing happened to my 1995 F150. Replacing a pump is a pain and not cheap.
Q:what is an air control valve, used for air line tubing?
air control valves are use for any sort of tubing or air pumps/air stones. air control valves are used to control the amount of oxygen/carbon dioxide allowed into your aquarium from the source. usually air pumps come with a air control valve but if not i suggest using one. also when using any sort of air line tubing connecting from the aquarium and out of the aquarium use a check valve! check valves are so important because it prevent water back flow out of your aquarium and into your cabinet,air pump, and of course you floor/carpet!
Q:How to replace a Hot Water Boiler Relief Valve?
I assume you are referring the pressure relief valve on the boiler water vessel, and not the oil line relief valve on the burner. The pressure relief valve is a very important safety device that needs to be properly sized and fitted to boilers and pressure vestals. It is sized and built to relieve as much as, or a percentage more than the BTU output of heat which it's burner can produce. It's inlet size and outlet sizes must never be compromised. It should match what was original on the Mfg.'s specifications on the name Tag of the boiler. (DO NOT TAKE FOR GRANTED THAT THE PRESENT RELIEF IS THE ORIGINAL.) Read the info on the valve tag and compare with the input and output rating on the boiler burner ratings unless your the original owner and know its correct. Because of safety reasons I would recommend.that you allow a professional HV-AC Boiler Technician to change out the relief. He would turn the boiler off, secure the water side and burner side and valves to Isolate your boiler (so as to not drain your system) take the pressure off, drain just a bit and remove the relief ,with the proper wrench. ********Safety note: Most Reliefs are built of soft metal (Brass) or Bronze when fitted out or into the pipe fittings it is very important to use the proper wrench and not place the wrench on the body or any other place on the valve but the proper shoulder made for the proper wrench. When the new valve is installed the the boiler needs to be placed back in original settings of valves and switches. Fill water back on, Vent air from system, fired and tested for leaks. The above safety notes are just a few reasons to have a Licensed experienced boiler man do the job Please be careful, Blessings Rangefinder
Q:how do i replace my EGV valve?
The EGR recirculates exhaust gas into the combustion chamber. It is usually two bolts, and sits ontop of the intake manifold. Usually pretty easy to change youself. Unhook the single vacuume line, take out the two bolts, and reverse the installation! Zach
Q:Question about valve lifters and camshaft break in.?
I have worked on many a V8 Chevy engine-350 305. I have done too many camshafts and lifters BUT i have NEVER,EVER heard that. If you remove the valve springs and attempt to run the engine, yes, your pistons will swallow up those valves.No doubt. No support, there part of the piston head. No I would say that after installing the cam lifters,etc you loosen up all the adjustable valves and let the engine start ( If It won't start and seems to chug-chug you have them too loose. So, in an orderly fashion loosen each and ever one maybe 2 clicks when the engine does start let run in this ragged fashion until ALL the valves are seated (You will know by the engine starting to get smooth) Then you tighten each one ( No order is necessary) Let the engine run for a good 25 to 30 minutes. The only problem here is the oil dripping or squirting onto the exhaust manifold.( This WILL start a fire) So, stay on top of It and flush them down every now and then. I used to, after I got the thing running in a orderly fashion, I put the valve covers back on loosely. Finger tight. Still watch It,though. But no, do NOT remove those inner valve springs.
Q:Need to find my main water supply valve...?
The main water valve is usually at the meter or front yard pipe where the hose valve is.
