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:General Help with replacing shut off valve under kitchen sink- Pics included?
Copper pipes are usually soldered. You might want to call a plumber for this.
Q:What is a Remote Operated valve ?
Rov Valve
Q:EGR Valve Position Sensor?
Typically when those sensors start to go bad, the EGR valve doesn't modulate properly between open and closed. When that happens you usually notice a sort of fluttering in the power delivery, often when cruising at a set speed but sometimes also when accelerating as a result of the wrong amount of exhaust gas being recycled back into the engine. You sometimes will notice a loss of power when accelerating as well. If the EGR valve is opening more than necessary it will be allowing more exhaust gas back into the engine than is beneficial....and that will reduce the amount of power the engine produces. If the EGR valve is staying closed more than necessary, you might not notice as many driveability issues but you'll probably notice your average fuel mileage decreasing a little and/or a check-engine light being triggered and/or a failure of an emissions test (even if the check engine light hasn't tripped) if you live somewhere that emissions checks are required.
Q:Amount of gas lost through relief valve?
Find the orifice size, then assume sonic velocity for ACFM flow rate times five minutes.
Q:What is a foot and check valve what's the difference between the two?
A foot valve is a check valve with a screen to stop debris. It depends on whether you're pumping water with alot of sediment.
Q:yamaha warrior valve adjustment?
The mechanics charge about $40. But, you can learn to do it yourself it is easy. Just loosen the outer nut. Turn the center one til it touches. Then back it off 1/8th of a turn. Then while holding the center one tighten the outer nut. Then your done with that valve, and repeat for however many valves you have.
Q:Is valve oil and rotary oil the same?
Simply said: nope
Q:how much would it cost to fix a busted valve in the head on a 1995 ford probe?
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:fill valve is squirting water?
lol! I think someones done a prank on You!
Q:hi guys..What is different between globe valve and stop check globe? Is that stop check globe=SDNR JIS std?
I am not even sure what you are talking about. a globe valve is a type of valve that can stop the flow by turn a handel on top of the valve. A check valve on let the flow go one way and stops the flow the other way. hope this help Globe valve From Wikipedia, the free encyclopedia Jump to: navigation, search A Globe valve is a device (specifically a type of valve) for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body.[1] Globe Valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug[2] can be screwed in to close (or shut) the valve. The plug is also called a disc or disk.[3][4][5] In globe valves, the plug is connected to a stem which is operated by screw action in manual valves. Typically, automated valves use sliding stems. Automated globe valves have a smooth stem rather than threaded and are opened and closed by an actuator assembly. When a globe valve is manually operated, the stem is turned by a handwheel. Although globe valves in the past had the spherical bodies which gave them their name, many modern globe valves do not have much of a spherical shape. However, the term globe valve is still often used for valves that have such an internal mechanism. In plumbing, valves with such a mechanism are also often called stop valves since they don't have the global appearance, but the term stop valve may refer to valves which are used to stop flow even when they have other mechanisms or designs. Globe valves are used for applications requiring throttling and frequent operation. For example, globe valves or valves with a similar mechanism may be used as sampling valves, which are normally shut except when liquid samples are being taken. Since the baffle restricts flow, they're not recommended where full, unobstructed flow is required.
