FAQ
Q: Do you produce valves with PN40?
A: Yes, but for PN40, we suggest materials of metal, like cast steel, stainless steel…etc. We could also produce ductile iron valves with PN40.
Q: Are you manufacturer or trading company? Which kind of valves do you supply?
A: We are a professional manufacturer of butterfly valves, check valve, non-return valves, gate valves, Y-strainer and so on.
Q: Will you do inspection before shipment? Whether Third Party Inspection is available?
A: We have a professional engineer team, so we can offer you the most professional technical support. All valves are tested twice before and after hammer pin to ensure its perfect sealing property and to make sure every valve is ok before ex-factory. TPI is ok but the clients should bear all fees.
Q: What kind of package do you use for these valves?
A: Valves from DN80-DN1400 will be packed in wooden boxes, but valves above DN1400 will be in wooden pallets. If you need wooden boxes for above DN1400, the price may be more expensive.
- Q: I have a curtis toledo compressor at my house. While moving it a helper dropped it on its side into the tank and broke off these 2 valves off the very top of the compressor. They had a copper line that ran off both of them and went over to the auto on/off switch, I'm guessing that's what it is. Where can I buy these or at least what are they called?
- They are the unloader valves. Look online for places that sell parts for air compressors.
- Q: whats the location of the pcv valve on on a 2001 bmw 740il (e38)
- In front of the engine slightly to the left and lower area of the throttle valve. It is a round black plastic canister supported by a teardrop shaped rubber with a cable connector at the top and 2 hose connections at the opposite end of the cable connector which are perpendicular to each other. BMW calls it the tank vent valve.
- Q: For instance, I am buying some new tires that don't have the valve stems on them, so could I remove my existing valve stems from my used tires onto the new tires? Is this recommend at all? Is it safe? Is it possible? Can this be done? why or why not? thank you.
- Ugh you could but you can buy new valve stems for about 25-50 cents each. I would use new ones.
- Q: When using seafoam through the PCV valve. Which side contains the vacuum? From the crank case of intake manifold? The brake booster line is very difficult to access and on their site it says I can apply seafoam through the pcv valve.
- On most engines the PCV Valve is located on the valve cover. You would remove the PCV valve from the valve cover but leave it connected to the vacuum hose. Otherwise you would have a severe vacuum leak and the engine would race wildly. With the PCV valve still in place the engine would idle somewhat normally. Pour the Sea Foam directly into the PCV valve. The Sea Foam would be sucked into the PCV valve and into the intake manifold. Be careful not to over do it on the first application. If this has not been done for a few years enough gunk can be washed out of the intake manifold that it can foul the catalytic converter. I would apply the Sea Foam. Have a friend shut off the engine while the Sea Foam is added. Allow the Sea Foam to soak for several minutes and do its job. Reconnect the PCV valve. Start the engine and drive the vehicle for several miles. This will allow the catalytic converter to burn off the gunk that and Sea Foam that has passed through the engine. Repeat as necessary.
- Q: Is it possible that if you never adjust valves the engine could lose a lot of compression? 1990 Suzuki VX800, 19,000 miles on the clock. No idea if it has ever had the valves adjusted, only got it 3,000 miles and 6 months ago. It is now not running and after a compression test, has 90 psi in the rear and 150 psi in the front cylinder. Don't really have the time yet for a leak down test. Could the exhaust valves be the cause of the low compression? thanks.
- Yeah, valves should be adjusted from time to time, both intake and exhaust, they are the two biggest areas of the compression system that would cause low compression. That old of bike probably needs a good 'go-thru' to see what's happening, the leak-down is your best bet at that happening.
- Q: When i disconnected my Diverter Valve and made it non-recirculating i drove down the street and my engine cut out on me. it will go a few feet and after the excess pressure is released (PSHH) the car cuts out. i reconnected the valve tubing making it rec-circulating and it works fine. im baffled i know VW is supposed to run a DV but last night i saw a stock VW GOLF running blow off and he was stock. any ideas? it is an after market DV made by forge.
- The OEM valve has a very low spring rate against the diaphragm holding the plunger down. The very first time you released the throttle the engine vacuum easily held the valve open. When not in boost the open valve will become an intake leak because its bypassing the MAF (mass air flow) sensor. If the MAF reads very low air coming in through the it, the ecm will start lowering the injector pulse width until it cant compensate any longer and will cut off because of the air leak. The Golf was running a higher spring rate to keep the valve closed at idle or has a chipped ecu to be able to release to atmosphere. Hope this helped out.
- Q: Holding my right hand up, I am a newbie :) any help is greatly appreciated.a) Comparing the shape of the valve to a golf tee, what is the correct name for the thinnest section of the valve(the part of the golf tee that goes into the ground)b) What is the correct name for the widest section of the valve(the part of the golf tee that the ball is placed on.c) The cylinder that the valve moves up and down in, is it just called the valve cylinder?d) In the valve cylinder?, how does the widest part of the valve keeps things sealed. Does it use a ring(simmilar to pistons) or is it some type of gasket material or is it just zero clearance metal to metal.e) The section of the (valve cylinder?) that is above the seal point or basicaly where the valve spring and the thinnest part of the valve is, does oil flow through here?f) Do (valve cylinders?) generate enough heat to warrant the need for coolant?Newbie City, I know. Any help is GREATLY appreciated.TY
- a) The very end is the tip. Below that are grooves that the keepers lock into. This is actually the thinnest part. Below that is the rest of the stem. The general name for the largest part in total is the valve head. b) Surface sounds right. Hadn't really thought about it before. LOL c) Valve Guide. These can either be just a plain hole in the cylinder head material, or often they have bronze inserts. Plain Guides are often repaired by a process called knurling. d) Valves seal to the head by grinding each at the same angle, (usually 45 degrees) and then they are lapped which is where an abrasive compound is placed in between, and the valve is rotated. This matches the surfaces more closely yet. The parts that seal are called the valve face and the seat which is actually a separate part that is inserted into the head, and can be replaced. e) Oil is supplied to that general area, by either holes in pushrods that lubricate the rocker arm, or in the case of rockers mounted to a shaft, through the shaft. In the first case, oil is supplied by the hydraulic lifters. In the latter, the shaft pedestals are drilled for oil passages. In both cases, oil is present in the area, but is not applied directly to the valves. In fact, the job of the valve stem seal is to keep too much oil from getting in the guides. f) Usually the coolant flowing through the heads is enough to carry away the heat, although some hi-performance engines employ techniques such as hollow exhaust valves filled with sodium. Most normal valves are solid.
- Q: I jsut got my valve cover replaced on my car what does that do?
- it covers up the valves to keep the oil in the engine
- Q: hi i just found out i have micro valve i and have allmost 30 years with willam sydrome any doctors know more what can happen what dose walking or others got to do with the valve will i stand for a longtime walk jump will one side get weeker then the other what about my hands and eyes my knees what will happend over the years when i get older ?
- I think you mean mitral valve prolapse. I have this. When I was younger I had a heart murmur and did several testing and nothing else became of it. Until recently when I was working out, I had pain in chest that didn't quite go away and went to the dr. and did some testing and diagnosed with MVP. Do not drink decaffeinated drinks b/c it will increase your heart palpitations. You can also be prescribe a medication to help with your palpitation. It's a beta blocker medication. It helps with your heart palpitations, but you should definitely go see another dr. if the dr. you're seeing is not very helpful or see a cardiologist. I was told to just go about doing normal activities.
- Q: I have a rainbird Sprinkler system. One of the zones the sprinklers do not pop up. Someone said maybe the valve is stuck closed from the winter. How do you open and close the valve manually to loosen it back up. and where would this valve be located in the little green junction box near where the zone starts????
- they dont really stick from the winter. i would say if the valve has a problem the diaphram needs replacing on the inside of it. ( all you have to do is find the same kind of valve and take the old parts out of the valve and replace them, the top, and the solenoid with the new valve's parts. they can be anywhere in your yard. ive even found the valve boxes buried under bushes. some installers don't put them in boxes, they just bury the valves. if you know where any of the green boxes are open the lids and see what's inside. sometimes more than one valve will be in a box. turn the solenoid on the valve. ( this will be the peice that the wire are connected to on the valve. dont turn the solenoid too much or it will come out. just a 1/4 to 1/2 a turn or so maybe a little more or less. and when you find the valve that turns on the zone 8 that is not working that is the valve for that section. you may even be able to hear the valve trying to come on when the timer shows it is running. if not, then check for power at the valve. if no power. there is a short, bad connection, or bad module in the timer. if power- replace just the solenoid first. if that doesnt work rebuild the valve. if you have no luck finding the box with zone 8 in it then try a few tips. get a screwdriver and poke around where some other valve boxes are. they may be close together. use a wire locator or hire a professional to locate the valve and show you how to repair it. to manually open and close the valve- open upthe solenoid like i said. or use the bleeder if the valve has one.
