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:electronic valves from the '60s uses?
Valves...or as we call them over here in the states, tubes...have a huge number of uses. These were basically what we had before we had transistors. There are tubes that regulate voltage, tubes that perform logic operations...audio tubes, tv tubes. What each tube does is pretty specific to the type of tube. Each one should be marked with an indentifying mark...such as 12AX7..or what you might see, ECC83 (just examples). Here's the great thing. You don't really need to know what they do. The people that are going to be buying tubes pretty much know what they're looking for. All you're mostly interested in listing is the tube type. You can get fancy, look it up and write down what kind of tube it is. However, you can't really nail down one application. I have tubes that were used in the RF amplifier section for VHF that, surprisingly, make EXCELLENT audio amplifier tubes. They have a wide range of uses...and for selling purposes, you only need to tell people the following: Brand of type type of tube (tube designation). You can include some information if you want...I'd make sure you mention they're untested unless you have a tube tester. But, for the most part, the people that would be interested in buying these things in the first place are already going to know what they're for. They're not something bought by the general public..it's a niche market. What you'll want to do though is look up those same tubes on OKorder to get an idea of what prices are going for. It's entirely possible you have a tube or two that are hard to find in todays market and would bring you MUCH MUCH more than the 11 shillings it retailed for. Case in point...I have a tube that sold brand new in the 60's for around $2....today..that tube can go upwards of 200 because they're not making them anymore. Oh...and make sure you throw the term vacuum tube in there too to get it in broader search results. I haven't heard anyone call them valves....unless they're from the UK.
Q:Explain terms associated with valve timing?
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:Does anyone know what those valves are/do in my picture?
To me that is a water mixing valve used in showers, you can see the plug on the top, so when the face plate is attached the tap tops are fitted to either side of the spout.
Q:2276 vw type 1---which is the intake and which is the exhaust valve? (for the #1 cylinder)?
The intake valves are the two rocker arms in the center of the passenger-side head. The exhaust valves are the rocker arms on either end of the head. For the #1 cylinder, the exhaust valve is the one closest to the flywheel side of the engine, and the intake valve is the next one towards the rear of the car. For example, if you're underneath the car and looking at the head, this is the pattern: Ex #2, In #2, In #1, Ex #1.
Q:My shower handle(diverter) seems to be stripped. How shall I remove all the shower valves?
those 2 tabs are element of the cartridge. a clean cartridge comes with a disposable piece that fits in with those tabs and a sq. on the tip so which you would be able to turn and circulate it with a crescent wrench, which in turn loosens so it particularly is pulled out. possibly you ought to apply a robust needle nostril pliers to get it to tutor in case you probably did not desire to purchase the hot cylinder first. I believe utilising the plumbers grease once you're putting in the hot one.
Q:where is heater control valve on toyota corolla?
standing okorder.com/ sign up and post in the 8th gen corolla forum. great ppl. been a member for years.
Q:what is overrun clutch solenoid valve ,is for my nissan maxima .My code scanner gave me this dtc definition?
Description The overrun clutch solenoid valve is activated by the TCM in response to signals sent from the park/neutral position (PNP) switch, overdrive control switch, vehicle speed and throttle position Will then be controlled. TCM TERMINALS AND REFERENCE VALUE ON BOARD DIAGNOSIS LOGIC Diagnostic trouble code O/R CLTCH SOL/CIRC with CONSULT-II or P1760 without CONSULT-II is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve. POSSIBLE CAUSE Check the following items. Harness or connectors (The solenoid circuit is open or shorted.) Overrun clutch solenoid valve DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE CAUTION: Always drive vehicle at a safe speed. NOTE: If DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE has been previously conducted, always turn ignition switch OFF and wait at least 5 seconds before conducting the next test. TESTING CONDITION: Always drive vehicle on a level road to improve accuracy of test. After the repair, perform the following procedure to confirm the malfunction is eliminated. WITH CONSULT-II Turn ignition switch ON and select DATA MONITOR mode for `ENGINE with CONSULT-II. Start engine. Accelerate vehicle to a speed of more than 10 km/h (6 MPH) with D position (O/D ON). Release accelerator pedal completely with D position (O/D OFF). WITH GST Follow the procedure With CONSULT-II. WIRING DIAGRAM - AT - ORVCSV Diagnostic Procedure 1: CHECK VALVE RESISTANCE 2: CHECK VALVE OPERATION 3: CHECK POWER SOURCE CIRCUIT 4: CHECK DTC 5: CHECK TCM INSPECTION This isn't something you want to do in your driveway. Take it to a decent mechanic and they should have it knocked out in about an hour or less, if it's the same one I'm thinking of.
Q:Is a EGR valve necessary?
It used to be a cheap fix. I haven't worked on the newer vehicles, but it used to be an F-shaped plug, with vacuum hoses, that you could replace in a few minutes. Price was under $20. The biggest problem, then, was decoding the codes! I just looked it up and it seems to be pretty simple, and similar to what I worked on. A small diaphragm valve that runs about $50. Ford would probably charge you $300 for the part and another $100 or so to put it on. The EGR valve helps with exhaust and, to some degree, gas mileage. In other words, if you live in a state with strict rules about emissions, you may fail the test. In proper condition, you may notice a little better fuel mileage. Of course, when I drove a sports car, I noticed that a good waxing helped my mileage. LOL I doubt that the Flomaster would cause a problem. This is a sensor issue that is, or should be, directly related to the EGR valve itself. Of course, I haven't worked on vehicles for years, so... Google this and see what you think. Location should give you some pictures to show where it should be on your Mustang and then you can see if you think you can do it. Then, check the prices. If your state is a pain, fixing it is probably cheaper than failing the emissions test. Besides, the more work you can do yourself, the cheaper it is. The only real difference between you and the guys who work in the dealership is a degree (piece of paper) and a fancy machine. You can do the same things they do.
Q:What do people mean when they say they have a 12 in valve?
