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: what is the reason for a 30 degree angle valve cut ? should i have this done on a Street performer 351 windsor with stock street heads and a mild cam?
Makes the intake and exhaust flow smoother.
Q: I am working on my riding mower Briggs and Stratton 15.5 OHV. After replacing my headgasket my intake valve did not move when I turned shaft by hand. I took it back apart and believe I have my pushrods positioned correctly but cannot seem to get the rockkers back over the valves and rods. Maybe its because I am a girl and just need to man up but I thought it should be easier. Anyone got any tips?
Panic? run around in circles? I have no thought what you prefer to do. yet in case you have been thinking, wanna comprehend how a lot of those little plastic rings that protection seal the bottle caps to the oil bottles i've got discovered under the valve cover? we could basically say lots, did they harm something? no, they only take a seat there, as there too great to pass down the oil galley and in the event that they have been that they had take a seat interior the backside of the oil pan or get caught to the oil pump %. up show screen, i'd desire to pass on approximately issues i've got discovered sitting in oil pans and caught to the show screen yet I wont, yet little products of RTV are on the ideal of the record, and if the show screen misses it your oil filter out won't.
Q: Can you please explain to me what an atrial valve is and what it does??
Only Veins have Valves that's in order to keep blood pumping inside, with the help of Skeletal muscles. About Atrial Valves, there's a valve in the Pulmonary artrey only.
Q: Is it posible there is underground valves? I looked all over my yard and can only find2 valves.???
Yes, electric valves are set on the Mainline which is under pressure. Usually in a loop around the home with the valves set where the zone starts. Some are designed to have a short mainline with the valves set in a large box next to a vacuum breaker. All valves need wires that run from the clock. Sorbet can be found with a metal detector if you simply can't find them. You can also set them to go off manually time delayed a few minutes, enough to go listen to hear the valve opening.
Q: im looking at buying a 1995 ford probe, but it has a busted valve in the head, does anyone know how much it would cost to have fixed?
When you say busted valve, do you mean a bent valve, or a broken valve? if you meant broken valve, i guarantee you my friend, that car is something that you do NOT want to invest your money into. a broken valve can cause and may have already caused all sorts of further damage. this can include exhaust fumes leaking into the cooling system and over-heating the engine, engine cylinder or gasket leaks causing oil to mix with coolant, broken timing belt, blown head gasket, and the list goes on. i HIGHLY recommend you stay clear of a broken valve. if you meant bent valve, this is generally not as serious, but is something to be very cautious of. the best way to check for a bent valve is to have a compression check done. a mechanic can do this, or you can do it yourself if you buy a compression checker. if the valve is indeed bent, the first thing you will want to find out is WHY it got bent. generally this happens because the timing belt slips or the valve has a leak from being stuck open. if this is the case, you might be looking at coughing up $300, maybe a little more, maybe a little less. but before dumping your money on fixing a bent valve, you want to get a professional inspection and make sure that this bent valve didn't cause damage to anything else. i hope this will help you with your question and with your decision on buying or not buying the car. good luck!
Q: Where is the illusive heater control valve?
The only valve i could think you are referring too would be the vacuum control on the back of the dash mounted heater controls. They do not have a valve in the coolant lines. The heat turned on or off by a vacuum operated door inside the heater box that merely closes and blocks the heat from escaping into the car. If you are having heater problems first make sure both lines running to the firewall feel hot/warm when engine is at temperature. Secondly you will have to find the actuators under dash on the heater box and make sure they are moving if not ck for vacuum.......
Q: What are the benefits of changing new cylinder heads and exhaust valves in the Main engine of the vessel? I am now studying a vessel which has a problem with their main engine. Frequent repair of cylinder heads (they usually weld it) and exhaust valves are the ones they do. I need to further give the benefits to be submitted to the vessel's management for them to buy new cylinder heads and exhaust valves as a replacement for the welded ones.
It sounds to me like this ship has an ongoing exhaust problem (maybe an obstruction of the flow) Or a low volume of cooling water (look at the water pumps) About the only reason to weld a head would be because of a crack and the most likely reason for a crack is over heating likewise the burned valves! Assuming that the engine was assembled correctly What else would cause the over heating except one of the above! Before you put new expensive heads and valves on this thing check out the over heating ( just because the Gage never shows hot dose not mean that it isn't! If the welding and the valve replacement was done correctly then there may be no benefit at all in buying new ones a compression test would tell,but a REAL LARGE benefit in finding out WHY this would happen especially more then ounce !
Q: The valves on our 2005 Pontiac Sunfire are bent and need fixing. Any idea of how much it might cost to have them fixed at a shop? Any estimates?
Most mechanics will put on a rebuilt head -- if you were to buy it, they cost approx $350 for the head assembly.
Q: Is it hereditary? My dad had a bicuspid valve and we got told it was hereditary but some doctors say it's not, my parents wanted to get me tested in case i had it so we would know in advance but the doctors here refuse to do it (I live in England if that makes a difference) my dad said he would pay to go private if it's hereditary. I know someone who had a bicuspid valve and 3 out of her 4 children inherited it, i know it's pretty harmless until i reach an older age but my parents and i would like to know now, i'm 13 by the way.=]
I am not sure you and your father want to know if this is hereditary. If you have say have a bicuspid valve now it is not going change any thing. You will still have norma life There are many like living normally
Q: Why would oil be leaking from a blow off valve?i own a 05' gti 1.8t, i have had the blow off valve for about a year now, its a HKS SSQV, but i just revently noticed that when it blows off, there is a spray of oil that comes out..... why would it be leaking oil through the blow off valve? i know VW dont really go well with blow off valves, but it hasnt given me any problems until recently....
vw has a pcv system it recirculates the crankcase air into the intake, your car if fairly new, but this is most likely the problem. at least its the most simple to check / fix. i dought the turbo is gone if its the stock ko3s, they can take a beating. the pcv valve is the black saucer shaped peice (kinda looks like the stock diverter valve) , its in the TIP by your N75 valve. these get filled with oil and start to dump in into the intake. did you switch the set up to run the BOV on the cold side? like off the throtal body hose? if so, this could STILL be the problem. if you take off your lower inercooler pipe and look inside for oil build up. and pull the n75 valve out and check it for oil. id think aboout replacing the pcv valve with a catch can. your real problem is yet to be noticed if your dumping the air out and not recirculating it into the intake, the car WILL RUN RICH, as it reads the air it adds fuel, but with a BOV your loosing some air BUT keeping the fuel. so id expect to see some bad cats and o2 sensors good luck
