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:what is the mechanism of deluge valves?
Deluge valves are used in special fire sprinkler systems. Open sprinklers or spray nozzles are attached to piping and to the valves. The valve is connected through control valves to a water supply system. The deluge valve consists of a housing, a swinging clapper like an ordinary check valve and a retractable keeper to hold the clapper tight to the valve seat. Electrical pneumatic or hydraulic mechanisms can retract the keeper, causing the valve to open. Other attachments provide for alarm sensors, gages and the like. See one at the link below
Q:new EGR valve?
i think your right. I'm not sure but a think your EGR valve is vacuum operated. If so, there is a vacuum solenoid to control the vacuum to the egr valve. There is also intake vacuum to this solenoid. Could be no vacuum to solenoid or a bad solenoid or wires controlling the solenoid. But also could be a completly different problem other than egr. You need to go back to the shop that put on the egr valve and find out why the egr valve didnt fix your problem. And either have them fix it right or get your money back.
Q:Where can I buy an electronically controlled valve?
good question! i understand of no good reason to not have some style of vent equipment on any motor vehicle. you like some style of crankcase ventilation equipment. the two an evacuation equipment for a drag vehicle or a PCV for a street vehicle. there's no reason to not use a PCV on a street vehicle. How did they music the engine? Did they use your headers? in the event that they ran it on a dyno, then that's going to in many situations be extremely lean interior the real international. Dyno tuning grant you with a competent beginning factor for installation any engine. How a great way off grew to become into the carb, you reported they replaced some jets. have been the heads quickly burn GM VORTEC heads? grew to become into the 22 stages improve on the crank or on the distributor? opposition SBC engines in many situations like approximately 35-38 stages finished improve beginning at an preliminary 18-20 with improve beginning at approximately 1500 with finished improve being performed at around 3000 rpm. Vacuum advances are infamous for over advancing, they do have the entire factor approximately giving extra constructive gasoline mileage and drivability for street automobiles. A street engine under easy load will stand lots of improve, which a vacuum improve will grant.
Q:what is meant by trickle valve?
Q:2004 yfz450 valve problem. Need Help!!!?
Valve guides wear and get loose, so the valve stem binding up in them is highly unlikely. If the guides are shot, they should be replaceable. Sometimes valve stems warp and will cause your problem, but the odds of it happening a second time are also unlikely. Once you tear into it, I guess the deciding factor will be if it's the same valve or a different one. When this happened, were your rpm's high or otherwise? I ask because if when high, I'd check for a broken or weak valve spring/s. Most have one spring inside of another to reduce harmonic vibrations and if the inside is broken, not only will you not have adequate spring resistance for high rpm running, but at a certain rpm the remaining spring will be quivering like a dog pooping peach seeds. The other thing that may have happened is the camchain tensioner isn't locking tightly. If so, that would let the chain jump a tooth or two and then Mr. Piston and Mr. Valve get into hand to hand combat. The old 6 cylinder Kawasakis were well known for having crappy tensioners that would do just that. However, with them, it usually happened during startup. Or, you may have had a camchain guide fail and with it laying in the bottom of the oil pan,the tensioner isn't able to take up all the slack in the chain. When you get it apart, let us know what you find because I suspect you need to be looking for the cause of the bent valve somewhere else than the valve itself.
Q:request information deep well foot valve?
The reason for the drop tube is to possibly save you replacing a pump. All wells silt in a certain amount. Your submersible pump can withstand a certain amount of this fine silt but if it gets to be half-submerged in the stuff it will burn out. With the drop pipe in place, the foot valve will plug up first, giving you warning and a chance to shorten the pipe above the pump. Rather than fitting the foot valve directly into the bottom of the pump, you would be better advised to replace the drop tube with a new piece. Also be sure to test your foot valve while you have it out of the well. Some are faulty right out of the box. I always screw on a fitting with a snifter valve that allows me to put 150 psi of air on the foot valve over night. If it doesn't hold that, it shouldn't be at the bottom of a deep well; it's just too much darn hassle pulling them.
Q:How does a thermal bypass valve work?
This Site Might Help You. RE: How does a thermal bypass valve work? How does a thermal bypass valve work, specifically in a car.
Q:how man cups does the miteral valve have.....?
Mitral valve has two cusps. The blood flows from the lungs, where it is oxygenated, into the left atrium then through the mitral valve into the left ventricle. From here it flows through the aortic valve to the rest of the body. Two cusps, oxygenated blood.
Q:How to remove sprinkler valve?
if the valve itself has gone bad, then you can actually replace it without haveing to remove it. richdells are now called irritrol valves. they are not that hard to replace the guts and top part of the valve. if you can find the same valve off the internet or a landscape store, just take apart the old one and replace the insides with the parts from the new valve, and replace the top piece with solenoid as well. if you cant find the same kind of valve, just dig up a nice hole and cut the pipes and replumb it. thats pretty easy too. the more room you have on the pipe to cut, the easier it will go. but richdells are now irritrols. the parts will be the same, just have a different label. ive seen the richdells last over 20 years though good luck and hope this helps
Q:What would happen if the EGR solenoid valve isn't connected properly?
try changing the egr vac solenoid, and the O2 sensor. dad has a 1992, and i replaced the egr valve, the solenoid, all the vac lines, and the O2 sensor to get rid of a missfire, and help mpg. we dont do smog tests here, so it wasnt for a smog reason went from 12mpg to 15 mpg. your supposed to connect the egr to the normally closed port on the solenoid. should be the top port. there is supposed to be a bit of foam glued to the VENT port. check your check engine light codes, you can do it in 5 minutes by jumpering terminals A and B. read more about it online. code 32 is the EGR code, its the most common code on these old trucks
