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:Does anyone know what those valves are/do in my picture?
Those are the hot and cold water pipes. You can turn off the water to the handle/knob by adjusting these valves. Although, it may be simpler and quicker to simply turn off the main for the home. This link has some similar examples and dialogue.
Q:Are valve cover gaskets easy to change?
Valve cover gaskets are very easy to change. Just make sure you get good gaskets, and when you tighten the bolts back down make sure you alternate bolts back and forth, don't torque one down and then jump right to the next one or you'll warp the valve cover since its aluminum. Start with one bolt get it slightly snug, then go to the one in the opposite corner and do the same, keep doing that until you have them all slightly snug, then start slowly torquing them down until they're all set at the proper torque. (Sorry I don't know the torque on those bolts).
Q:how do I turn on a rainbird valve manually?
Rainbird Manual
Q:Replaced a Rain Bird control box, Power on and not controlling valves.?
I would test the leads inside the control box first... You will have to run the controls manually to troubleshoot the problem. Get a voltage meter to test for the 24 volts at the transformer connections inside the box... If you do not have the 24 volts then the problem will be the transformer. If you have the correct voltage from the transformer then you can test each of the station terminals to common. Test through each station to see if you have 24 volts at each station terminal, but you may have to remove the wires off to test. If you do not have power coming from each station… then the problem will be the rain bird control. The next step would be testing the wires… If you reconnect the wires… test just prior at each valve location to see if you have the 24 volts between the common and each station wire… if you can prove out that there is 24 volts at this location then you’re down to the final testing. Reconnect the valves – one side to the common and the other to each station wire… Getting the power (24v) to the valve should have cleared your problem. Good Luck… Running the valves manually will not affect the operation of the rainbird control... but with my rainbird valves.. you can shut off the valves completely and disable the electrical controls of the valve... make sure that you have not closed the valve off manually preventing the electrical side... a problem with rainbird controls. This does not have anything to do with residual water in the lines... I would test this side first before you get into the electrical side... could save you a lot of time.
Q:Mid eighties GM egr valve problem
EGR valve got sooty,and rusty and dirty and then they dont work right. They either dont open or they get stuck open and cause the car to run lousey. If the valve has been i the car since the 80's it is probably about time to either clean it or change it. do you have haynes or chilton manual for the car? they explain alot.
Q:97 explorer valve body solenoid question?
What are you? 9 years?
Q:Blow-off valve requirements?
A blow off valve releases the excess pressure from your forced induction system when you close the throttle plate. It prevents turbo surge. If you install one on your naturally aspirated vehicle, all it will do is get you laughed at. As for the manual, READ IT! Blow off valves have nothing to do with the transmission, so automatic or manual, makes no difference. Word of advise: Don't work on or modify your car. You'll make it slower at the very least.
Q:Check Valve for Air Pump?
Check valve designated that it lets air go in one direction and stops water from going in reverse direction. For example if your airline gets disconnected from airpump by accident and drops on floor water won't gets syphoned out frmo tank to floor. You'd be surprised how much water can end up on floor in this scenario ;-) In order to install check valve you have to cut airline somewhat in halfs and put your checkvalve between pump and airstone. Arrow shows direction in which it passes air.
Q:Which side is open for a pipe main shutoff valve?
You turn the valve counterclockwise to open or turn on the water. You would turn it clockwise to shut the water off. Think of it as you would as if you were turning a screw. Right is tight. Be sure you open the valve all the way so the packing in the valve is tight, some valves leak a little, especially old ones, if the valve is only opened partially.It pays to work a valve occasionally to keep it supple, otherwise the packing or rubber washers dry out and start to leak. When you are operating a ball valve, one with a flat handle that only turns 1/4 turn or 90 degrees, when the handle is going in the direction of the pipe, the water is on. When the handle is going across the pipe, the water is off.
Q:Heart Valve question - stenosis and regurgitation?
stenosis means thats it difficult to open the valve to allow a full ejection of blood. regurgitation is caused by an insufficient valve, in which the valve does not close all the way, and thus allows blood to flow backwards. For instance, the two AV valves (mitral on the left, tricuspid on the right), are prevented from prolapsing by chordae tendonae, which are connective tissue fibers attached to pieces of cardiac muscle (papillary muscles) on one end, and the edge of the valve on the other. If these chordae tendonae break, this may cause blood to flow back into the respective atria during ventricular systole. Valvular insufficiency and prolapse will cause diminished stroke volume. Valvular stenosis, on the other hand, is typically caused by a buildup of material on a valve which inhibits its movement. This buildup could be many different things, to name a few: valve calcification due to hypercalcemia, bacterial adhesion and growth due to sepsis, plaque (cholesterol bound with free radicals) buildup on the valve, a fibroma, etc... If the valve's opening is inhibited, and it does not open all the way, there will be a diminished blood flow into whatever chamber is next in the sequence. If an AV valve is stenotic, the ventricles may not fill properly, and preload will be low, which will lower ejection volume. If the semilunar valves are stenotic, then the ventricles will likely hypertrophy because they will need to work harder to force as much blood out, because blood entering the ventricle must equal blood leaving the ventricle with each heartbeat (starlings law of the heart).
