1.Features Of High Performance Metal Sealed Butterfly Valve
VBJG High performance metal sealed butterfly valve adopts “Inclined oval disc radial dynamic balance sealing system” to attain the frictionless action between the gasket of the disc and the sealing face of the seat before valve closing. The pressure angle is bigger than the friction angle on the sealing face for which the extra-low open resisting force and rapid closing automatic tally sealing action are available. The valve features with advanced construction, reliable seal, long life, low cost.etc. It is an economical practical automatic control valve providing both control and cut-off functions and uses to the fluid services with large flow, low pressure drop and low seat leakage.
Features: Patent No. ZL200820238488.1
1. The optimum design of eccentric size ensures that the disc’s seal ring can be disengaged from the seat ring sealing surface immediately during the opening and closing process, which leads to no friction, no jamming and small operating torque, and high sealing performance and zero leakage are available.
2. Corrosion resistant alloy replating is used for seat to make sure high reliability and long service life.
3. The special processing technology is used for high precision and field-replaceable for seal ring.
4. Special non-metallic materials are used to make sure high temperature performance, strong self-lubricating and low friction. The dust and granular media can be effectively prevented into the space between the stem and body to avoid jamming.
5. High-strength stainless steel is used for integral stem and other parts to ensure high allowable pressure differential.

Q4:What Is Our Normal Payments Terms?
- Q: I had to replace the seat washers/stems etc in order for the constant drips from the kitchen faucet to stop. It did; but when i went under the sink to turn the water valves back on, the hot water valve felt as something inside it went smooth??? i can turn the hot water valve left and right but nothing is happening. No hot water at all from the kitchen faucet..Also there's low water pressure from the cold water that only came about when I tried to turn the hot water back on from the valve underneath the sink
- pull off the handle and try and turn it with channel locks or pliers, and remove the aerator screen and clean it. its very common for them to get plugged up after you turn off the shutoff valves and reopen.
- Q: here are pix's i want to no, if there is a easy fix or does it have 2 b machined thanksi think it use to have a bent valve in it
- Yes the faces and seats need to be recut, just fix it right the first time.
- Q: i ha valveve a knock on the driver side .and i have to remove the intake manafold to get to the valve
- Really? I find that innane. rocker covers usually come off pretty easy, and are well above the manifold-unless its a sidevalve???
- Q: Ok. i just got my trumpet and i barely know anything about it. my trumpet book says, oil your valves but i cant even get them unscrewed, its like theyre glued in there...or maybe im just doing something wrong. Helppp
- Flip your trumpet over and take some valve oil and put it in the small holes on the bottom of each valve casing. If this doesn't make sense to you take it back to the store you bought it from and have them help you with it. DO NOT FORCE THE VALVES OFF THE INSTRUMENT IT WILL DO MAJOR DAMAGE!!!!
- Q: i know its going to drop some oil, im just wondering to what extent? how much oil is going to spill out?
- If the car gets to sit for several hours that should not be a problem. Otherwise give the other paint 72 hours to dry hard before removing the valve cover. You may have to rag it a bit. Use hi-heat paint on the covers.(follow directions on the can)
- Q: Sohc ZC (d15) honda I'm going to be painting my valve cover am I going to need new seals? What do I need to take it off and put it back on ? Please help I have the high temp sand paper all ready to go I just want to be ready
- Valve cover gasket. Make sure it comes with the spark plug tower seals or you need to buy them separately. It's best to bead blast the cover before painting it.
- Q: I have a T4-T10 and L5-S1 spinal injury and I recently found out that my tricuspid and my mitral valves leak. I have never had heart problems before I got the spinal injury. Do you think the valve leaks could have been from the trauma when I received the spinal injury?
- I wouldn't think the trauma would directly injure the valves. Were you in the hospital for a long time following that injury hooked up to IVs? With IV catheters there is the possibility of bacteria entering the bloodstream and causing damage to the valves. Maybe that is why you developed valve issues. Also I wonder if there is the possibility that the massive immune and inflammatory response generated by that much trauma to your body may have caused some damage to the valves. I've never heard that happening, but I imagine it's possible. Also it may just be coincedence and you may have had the valve issues before but never had reason to check them out. A small leak in the heart valves is very common as people get older.
- Q: My doctor detectd a heart mumer. I am 48 years old. Had a echocardiogram performed. He says that I have a sightly irregular valve and I do not need to take precautions. I run three miles a day. I have heard that this condition makes your heart more suceptiable to infection. You should take antibiotics when dental work is done. My GP is a man of few words. Just says continue as usual and nothing needs to be done unless there is further symptomns. My question: Should I follow up with a heart specialist or would it be over doing it? Should I go on antibiotics when I get dental work? Can this Slightely irregular valve get worse?
- Actually this is quite common and is usually not a concern. It is generally felt that the misshapen valve leaves you more open to potential infection, especially when having dental work done. But this is quite rare. Still, if the dentist knows you have the condition they will require you to take a loading dose of antibiotics to protect yourself when you have any work done. Occasionaly I would forget and they would send me home. Geeze. Still, better safe than sorry. In the big scheme of things it means very, very little and you will probably never know its there. There is no need to see a specialist, again, this is very common and very, very rarely causes any problems. Just keep on keeping on and you will be fine. Just consider the antibiotics pre-dental work. All you have to do is call the doctors office, tell them you need some for a dental visit, they will fax over a script to the pharmacy, you pick it up, eat something first, then take the antibiotics and you are done, no big deal. I hope this helps.
- Q: like they say on 4 strokes you gotta go get valve jobs, and they cost bout 300 they say? well what does the mechanic do? can it be done at home and your just adjusting them?
- Take the head to a machine shop you have to grind the valves or replace then,Same with the seats Then replace the guides and adjust the valves Not a driveway Job
