About Product
A butterfly valve consists of body ,stem ,disc , actuator (manual actuator, worm-gear actuator , aerodynamic actuator or electric actuator) , and PTFE butterfly valve can implement the process for turning on turning off and regulating the flow by the circumrotation of stem and disc that is droved by actuators.
1.Simple and compact construction. Small in size and light in weight. Easy transportation, installation and maintenance.
2. Quick 90 degrees on-off operation. Minimized operating torque ,energy saving.
3. Excellent sealing performance with ZERO leakage. Long service life.
4. Wide selection of materials ,applicable for various media..
5. Flow curve tending to straight line. Excellent regulation performance.
- Q: We have an ejector in the basement for an in-law apartment. When the check valve kicks in, it can wake us up from a sound sleep. A very loud thunking. Any ideas?
- the check valve would be installed just outside of the crock vertically. The noise I doubt is from the check valve itself. I'd guess it is the pump shutting off and the pipe isn't fastened securely, so it bangs. Check to make sure that the run of pipe leaving the crock is fastened securely. if this is the case the only other option I oculd think of would be to re-position the check valve on a horizontal run of pipe as close to the crock as possible. Most check valves I have seen for ejectors are compression type, it will be messy but not to complicated. Keep a bucket handy, when you crack open that check valve you may need it. Flush the toilet until the pump kicks on a few times, this should clear out most of the nasty stuff. You may also need a short piece of 2 pipe and some couplings to make up for the space of the check valve. If you can hear the water flowing out when the pump kicks on and don't hear it draining back into the crock when it shuts off, the check valve is probably still good.
- Q: i have been having these chest pains and i went to the doc. they did an ekg, blood test for enzymes and a echo. Well today i went back for the results of the echo and was told that i had a leaky valve but it was nothing to worry about and that there are just trace amounts of valve regurgitation. Im only 19 and i have no other history of heart problems or diseases should i be worried...they said i didn't need any anti biotics or anything and that it wouldn't kill me just to watch for it as i age into my latter years of life 50-70, but im still kinda worried..anyone else have this? im also pregnant and im concerned as to how this will affect my pregnancy, labor and delivery????
- well, firstly, almost everyone has trivial valve regurg. it is considered okay and not a need to be alarmed by it. its the severity that matters most. so i see that u have a valve regurg but just trace amounts so it should be alright. this may well due to your pregnancy, (just a possible cause) that u get this but it may also be all along even before pregnancy. it doesnt affect your pregnancy much unless u have hypertension. it is called hypertensive pregnancy. this is much attention needed than your current trivial regurg. but do go for another scan after pregnancy to make sure that the regurg doesnt worsen. the bottomline is... dont worry. you're doing okay. happy pregnancy! :)
- Q: my valves are making a taping sound and i lost a lot of power and need to know will lose valves make me lose power so can someone tell me what they are seat on thanks

- Q: behind the valve cover of the #1 and #2 cylinder there are 2 intake and 2 exhaust valves I need know (cylinder #1) which is the intake and which is the exhaust. thank you in advance.
- 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: When you regulate flow with a valve in a fluid circuit, obviously the flow changes. But mathematically, it changes in function to what? the minimum cross-sectional area? I mean it has to have something to do with some integral of sth (since a valve can change the cross-sectional area of a portion of the tube with length of almost zero and the flow would still change dramatically). I have no idea how to work this through. Can you tell me what changes when you close a valve, which makes the total flow change?Please answer asprecisely as possible, this is for a college essay! thanks in advance!
- A valve reduces the cross-section of the pipe. .
- Q: I'm a 68 year old male. i've had mitral valve regurgitation all my life . recently an echocardiogram listed it as 3 plus. I'm in otherwise good health and continue to jog 3 miles three times a week at about a 9 minute mile rate. Is surgery advised.
- relies upon if there's a click and no indications and the Echo would not point out a leak around the valve you do no longer want therapy. in case you have a click and a murmur and the Echo indictes a significate leak, could lead on directly to shortness of breath and deliver approximately heart failure. will require medicine to capability heart function,if indications do no longer respond to therapy surgical technique in line with risk necessary. Has your Dr ordered a 24 hour Holter computer screen? good luck
- Q: i hav no clue wat it is or what it does, but i was goin to buy an 08 mitsubishi lancer but then i read that the valve guides in mitsubishi engines wear out really fast and it causes some problems.what kinds of problems?how will this effect the car?Should i go ahead and buy the car?
- will burn oil, needs replaced and valves resetted in the heads. the heads will need to be removed and taken to a machine shop for this.
- Q: here's some additional info asking of my question...I plan on buy a BLOWOFF VALVE and woundering where does the BLOWOFF VALVE goes in my car or do i have to replace with stock EGR VALVE using same hoses or help me please don't wanna screw this one up
- A blowoff valve is used in high-powered turbocharged engines. It allows for compressed intake air to be vented out to the atmosphere to reduce turbo lag that occurs due to excessive pressure buildup. It's not necessary for factory turbocharged engines, but if you have designed your own system you may want to add one. If you are unfamiliar with how turbocharging works - other than it makes your car go vrooom - then I highly suggest you take the car to a speed shop and have them analyse the car to determine whether you even need a BOV.
- Q: I have a 97 ranger 4.0L that takes 10w-30 and I'm going to be changing the oil soon. It has some valve clatter I'm just wondering if I can use a thicker oil such as 15w-30 or maybe a 10w40?
- 10W40 works fine. That's all I've ever run in my Explorer - and presently it has just under 200,000 miles.
- Q: I own a 1982 Pontiac Firebird base model which has recently started leaking oil from its Proportioning Valve. I have looked all over the internet for a replacement, and it turns out GM has discontinued the part. Now im faced with difficult and risky task of attempting to fix it, or turn it over to a repair shop as a last resort. The valve seems to leak out of a small circle with a hole the size of a needle inside which was covered by a rubber gasket. I have no clue what this does, and how to repair it.
