Product Description:

1. Structure of Check Valve Description

This product is designed and manufactured fully in accordance with API Spec 6A wellhead and Christmas tree equipment standards,and can thus be used interchangeably with the products manufactured at home and aboard,which tally with API Spec 6A specifications ,or used to form a complete system.

This is a type of check valves which rely on the pressure of working medium to get meal-to-meal sealing between the core and body(seat). The higher the medium pressure,the better the sealing performance. It is always able to withstand the pipeline pressure within the value cavity.

The body of the valve is forged with alloy steel,which has solid mechanical properties and is able to withstand high pressure in safty and reliability.

The bonnet and the body of the valve are connected with blinding bolts. Sealing washers are used to seal up the bonnet and the interior wall, which reduces the space in between to a minimum (designed as 0),thereby considerably minimizes the erosion of the bolts and the bolt holes,caused by erosive  media,and also decreases the load taken by the bolts.

2. Main Features of Check Valve

2) Designed with the relief valve
3) Designed with the plane thrust bearing structure
4) Designed with the meal-to-meal sealing structure

Q:how to protect a foot valve?
most foot valves i have bought come with a strainer attached perhaps you should look for that type. if your valve has a strainer you may consider making a further coarse strainer out of a ball of chicken wire and place this over the foot valve assembly(thats what i do for the cold water supply to my house) don't compress the chicken wire very small as it will block up i tie the wire filter on with galvanized wire then i can easily replace it if necessary ps i tried stainless steel pot scourers but they were to fine and blocked easily
Q:bmw 740il pcv valve...................?
In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.
Q:Is mitral valve anything to worry about it?
In 95 plus percent of cases so-called mitral valve prolapse is a normal variant. If yours was other than a normal variant your cardiologist should have discussed this with you. As such I would not worry. JR
Q:Leaky Valve?
yes. surgery. otherwise you'll have murmurs either all the time or occasionally depending on the leakiness. you must certainly see a doctor. there are no external treatment for this because protein will be used for muscle and other such things. your heart valves are formed while still fetal and grow with your body for about 30 years. repairs almost completely stop at 15 because stem cells are rareified. this is why scientists look into stem cell research. i cant remember who but the japanese fellow that cloned the first dog also started research into stem cells for the heart and was not only able to repair the hearts of frogs, sheep, mice, pigs, etc. but he also grew a fully functional human heart in a pig with all but O+ blood types. basically just talk to a doctor and poke around. your heart is literally vital. dont mess around or hold back for any reason. search until you are better.
Q:Riding with a Schrader/Presta valve adapter?
Yes, just leave it on the valve while you ride. I tuck mine in my seat pack, but there's no reason you can't put it on the valve. The presta valve should be screwed shut like normal, then just put the adapter on over it. One of the best little gadgets to have if you ride in the country. Lots of people have portable or shop air compressors, but only *real* cyclists will have a pump or air chuck to fit a presta valve. If you inflate your tube with CO2, be sure to let it thaw out before you unscrew the adapter to close the presta valve. It's easy to lose air or tear the rubber at the base of the valve if you don't. I rode with a guy that used to just tuck his adapter and a patch kit in the leg of his shorts because he wanted to travel ultralight. I guess you could do that, too, but I'd worry about driving them into your flesh if you happen to crash and land on them.
Q:Isuzu Rodeo OBDII code P0440: EVAP purge valve solenoid?
I have seen many of the Rodeo's purge valves malfunction causing rough idle and that clicking coming from the valve. It is not normal behavior for that purge valve. Double check all hoses for any hair line cracks, they tend to crack on the bottom side alot. Otherwise replace the purge valve it make a huge differnce in the vehicles idle and performance. Also a intake cleaning service helps quite a bit too, most lube centers and shops can do it for about 50-60$. That cleans all the carbon out of your intake plenum, port runners, valves. It may help the valve to stop malfunctioning also, have seen that service clear all codes and bring back lost power and rough idles clear up.
Q:1999 Pathfinder Suction Control valve?
hold the computer near the Pathfinder it will suck data directly off the internet (NO WAY) what you need is a complete diagnosis by a experenced Technician or a Nissan Technician. Idle control is on the bottom of the throttle chamber or on the intake manifold. Stalling and Dieing may be caused by a Distributor or air flow meter fuel pump or clogged up fuel filter. Suction control valve in not a part on your year pathfinder good lick
Q:Bent Valve!!!!!!!?
Never paid for so I dont know, BUT You will have to replace that new timing belt again. OR make sure they install it right. Seen one case where a timing belt came loose due to the tensioner not being replaced with the belt. Quiz your mechanic and see is he even knows about the belt and tensioner. If it jumps, you can bend all valves. Makes me curious how just one valve out of 16 got bent. Replacing the head is a tough job and a few issues can arise. BUT You should recondition if you are pulling it for one valve.
Q:Defects in which valves would produce the following?
Tricuspid regurgitation: Symptoms of right-sided heart failure, such as ascites, hepatomegaly, edema and jugular venous distension.
Q:In aircraft reciprocating engine, if valve spring surge happen?
Its in a car engine but the fault is near the same. The good news is that in aircraft there are mostly multi-spring valve springs to help prevent the resonance problem that can happen with a single spring. (If one goes resonant, the other one doesn't.) I think what that means is that if you have valve spring surges in an aircraft engine, you probably have a broken spring or weak on the assembly. (just a guess but if they don't go resonant at the same time then how would you get the surge?) The affect, not good. Result - rough at a certain RPM or range of RPM even temp. related Feeling - rough
