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:
1、The 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: 2004 R6. Runs really well... never had a problem. Has 24K miles on it. Yamaha calls for them to get readjusted at the 26,600 mile mark. So I have a few thousand more and then I'm gunna have them adjusted.I can already hear them tick especially at idle because when riding, my exhaust is so loud and all you can hear is that and the wind. Anyway, this time will come up before I know it.Just curious... what happens if the valves remain loose? Will it affect performance? How do you they become loose and is it ok to ride a bike with them like that... atleast until the specific mileage when they are supposed to be adjustd?
- could cause excessive crank case pressure if the duration is way off, i know from experience. Short valve duration=blow by because exhaust gasses have less time to escape the cylinder. Could potentially cause leaks due to blow by gasses
- Q: I am trying to repalce the water turnoof valve under my sink but the valve just keeps turning and no progress is made to get it off so I can put on a new one. I am turning it clockwise but it just keeps turning. Can someone please tell me how to get this off? I do not want to have to call a plumber for something that I might be able to fix myself.Thanks.Sandy
- basically component to the diverter valve is broken, besides the undeniable fact that, it extremely is terrific to replace to total diverter stem. If their are 3 handles, you are able to do away with the middle one devoid of turning the water off. Then convey total stem with you to the ironmongery shop. There are quite some video clips on youtube and different ironmongery shop factors of interest in case you like help. good success.
- Q: How do I adjust the valves on a 96 Blazer, 4.3 V6? When we tighten them to torque specs there is no compression, then when we loosen them and get compression, they loosen up to loose after its been running...any help!, THanks!
- first you need the specs on it. then get a feeler guage to adjust the correct clearance from the rocker arm to the valve stem. then tighten the jam nut to torque. a service manual will give you the right info you need and sequence of adjustment
- Q: Liquid propane leaving the reflux pump of a distillation column flows through a 3.5 in ID pipe at a flowrate of 90 lbm/s. There is a flowrate control valve in this line, and it is set such that the pressure drop across the valve (delta)P=15 lbf/in^2. Upstream of the valve , the pressure P1=18 bar and the temperature T1=310 K. Assume there is negligible heat transfer with the surroundings and that the density of the liquid does not change significantly.a) What is the kinetic energy change across the valve?b) What is the enthalpy change across the valve?c) What is the temperature change across the valve?d) What is the entropy change across the valve?
- If there is NO change in the density of liquid propane as it passes through the valve, and if the size (area) of the pipe upstream and downstream of the valve is the same, then a) there will be no change in the velocity of propane, hence there will be no kinetic energy change. b) this is a process of throttling, with no change in kinetic energy, hence there is no change in the enthalpy. c) temperature change can be determined using the detailed property table of propane, but if it is an almost-incompressible liquid, then this too, will be negligible. d) dh = T ds + v dp. Since there is no change in h, integrate this along a constant h line from inlet to exit (upstream to downstream) and you will get ds = -(v/T) dp. Since p reduces from inlet to exit, the change in entropy will be positive. This is as expected. If we assume density (=1/v) and temperature (T) to remain constant, then the change in entropy will be s_downstream - s_upstream = (p_upstream - p_downstream) v /T.
- Q: Exhaust valve opening (EVO)Intake valve opening (IVO)
- HI You answered it your self... exhaust valve opening (EVO) is when the exhaust valve opens.. and the same for the intake (IVO).. When the EVO happens the motor pushes the exhaust (burnt fuel) out of the motor when the IVO happens it sucks gas into the motor to get burned and make power.. Exampe of a 4 strock motor. 1) piston goes down , sucking in air and fuel (IVO) 2) piston goes up compressing the air and fuel spark plug fires ignighting the fuel 3) piston goes down turning the crank powering the car from the explosion of Fuel. 4) piston goes back up pushing the spent fuel out. (EVO) then repeats. On a 4 cylinder car this happens 4 different times on an 8 cylinder car 8 different times and on 6 cylinder car 6 different times. When one cylender is firing another well be coming up to push out its spent fuel and another well be going down drawing in fuel and so forth.. good luck tim EDIT IVC = intake valve closes EVC= exhaust valve closes
- Q: I need a ball valve that when you shut it off it sends a signal to a light that indicates that it is off.

- Q: I have a '98 Dodge Caravan 3.0 and the valve cover gasket is bad. How do I replace it?
- you are going to not like this first drain coolant 2 remove the throttle body linkage remove the pipe going to the egr to exhaust manifold [helps to use penatrating oil] remove assorted hoses to get to removing the upper intake plendeum {not the lower intake] [you need to put a shop towel over the open intake ports at the engine to keep any and all debries out of the intake ports to the engine] you should be able to see the valve covers by now remove the valve covers bolts remove the valve cover clean the gasket surfaces on the cylinder head [don,t leave ant debries in this area or in the valve cover [cleanlyness is a really good thing at this point in the build keep the crud out] there are some half moon seals that need to be replaced at this time located on the ends of each cylinderhead put a light bead of RTV high heat silicone on the rounded side of the seals and install the seals in thier half moon bores the RTV high heat silicone will kinda squish out of the seal don,t let the beead get carried away wipe of the sealent with a clean towel [shopcloth] not paper towels put a little RTV high heat silicone across the seal s flat side wipe flat with your finger install the valve cover gaskets on the valvecover [a little automotive contact cement for weaterstripping helps hold the gaskets reinstall everything fill coolant system change the oil and filter look for leaks a book or parts guy should be able to help find the right touque to tighten the bolts remember cleanlyness works here good luck should take about 8 to 10 hours note do not reuse any gaskets any where new hoses would not be a bad idea along with a thermostat ihawk3
- Q: My son was born with bicuspid aortic valve which has developed a leak. He is now on enalipril 2x per day to decrease the afterflow and buy some time before he has to have surgery, but the doctor has discussed our options and we basically have to choose when it comes down to it, whether we go with a valve repair, or valve replacement and if we do replacement we can do mechanical or donated valve or The Ross procedure. And he will probably be under 5 yrs old when this needs done, (he's 2 now) so I would like to keep him off of coumadin (blood thinner) so he can play sports in school if he would like. But I also want to do what is the best for him long term. Any advice would be helpful. thanks
- I okorder /
- Q: recently changed head gasket. could valves tap from the push rods being mixed up? they all seemed to be the same size and i know the other side was exactly the same when put back together but this side is mixed up. could this make the valves go crazy? and i need to replace my water pump because its getting very hot and no coolant moving. and everything is smokin up, took off oil cap and it was steaming. would that have anything to do with making the valves tap?
- there okorder a good site that will help you fix your car and its free and you can ask master tech for help.
- Q: Hey, ive got a scooby and have a baileys dump valve that is a loud deep wooooosh sorta sound. What dump valve does the more high pitch sound? also they dump valve with the higher pitch seems to need less presure ta dump, mine needs alot of pressure before it will dump loud?
- if i remember rite you can adjust the control settings for your dump valve so that it will dump at a lower pressure and a lower pressure dump should also give you the sound that you are looking for.
