General valve using the market long-term, widespread Water Leakage, rust phenomenon, soft sealing gate valve produced by the introduction of foreign advanced technology of the enterprise. To overcome the poor sealing gate valve, general elastic fatigue, rust and other defects. Soft sealing gate valve is a traditional valve replacement products, the compensation effect of using flexible gate produce small deformation, achieve good sealing effect, the valve has a light switch, reliable sealing, good elastic memory and long service life and other significant advantages, can be widely used in water, sewage, construction, food, medicine, metallurgy, electric power, textile, energy systems, fluid pipeline regulation and closure devices as.

The characteristics of:

- flat style seat

The traditional control valve often pass after washing due to foreign objects such as stone, wood, cement, paper, and other debris deposited on the valve at the end of the groove. Close but not close easily lead to the formation of Water Leakage phenomenon, the lower part of the soft sealing gate valve with water using the same flat design, easy to siltation caused by debris, the fluid unimpeded.

And the overall package glue

The valve plate is made of high-quality rubber overall, the outsourcing of plastic, making the domestic first-class rubber vulcanization vulcanization after the valve plate to ensure accurate geometry, and the rubber and ductile iron gate is connected firmly, not easy to fall off and good elastic memory.

And corrosion resistance

The valve body adopts epoxy coating powder, can prevent the corrosion and rust, and can be used for sewage systems.

And not easy to break

Traditional cast iron garden gate often hit foreign objects, collision or overlap caused by the fracture phenomenon. Because the valve to switch to ductile iron, this is the case already significantly reduced.

Three "O" ring seal

As the valve stem with three "0" ring ring seal design, can reduce friction when the switch is greatly reduced, Water Leakage phenomenon and can cut off the water supply construction not replace sealing ring.

And help to drink

Due to the internal body to non-toxic epoxy resin coating, gate of the inner and outer surfaces are completely coated with rubber and can not rust or corrosion of water available to drink.

- Casting valve

Valve body casting, precise geometry makes the body without any internal finishing to ensure that the valve seal.

And light weight

The valve is made of ductile cast, lighter in weight than conventional gate weight about 20%-30%. Convenient installation and repair.

Q: Why are pig hearts valves used as replacements for damaged heart valves in humans? Are there any complications and are they still used today?
They are called porcine valves... they are used very frequently because you don't have to be put on anticoagulation. But, the down side is... they only last about 15 yrs and then they have to be replaced. A pigs heart is pretty close to a human one.
Q: my dad's friend died, and dad had been keeping some valves of his. now we've been left with about 400 valves and i'm going to sell them.my main question is what are they used for? i need to write a description for ebay but have no idea what they're for! anyone know?also, how much should i sell them for? on the box it says 11 shillings, which i worked out as ?1.32, but how much should i sell them for on ebay? there's prices on ebay that are about 50p to ?1.50 for most of them, but some are about ?7 but have no bids at all. how much should i start the bidding at?also, if you could give me any other information that i should put in the description, i would really appretiate it :)they are mainly 'Mullard' valves (the company name) but some are 'MAZDA'thanks! :D
Valves (we call them 'tubes' here in the US, but 'valves' is actually a better description of how they work) were used on all kinds of electronics up to the 1970s. Radios and TVs mostly but also musical instrument amplifiers, PA system, etc.etc. In fact some high-end 'audiophiles' believe valves give you a better sound, so even today there are special (very expensive) amplifiers for both stereos and for guitars, that still use them. Only certain ones though, the ones that do final-stage amplification. And they still make the valves for these. People will want them for restoring old electronic gear, and to keep on the shelf in case one of theirs dies (they have a limited life). I have no idea what they're worth, but the answer to that question is: Whatever someone is willing to pay for them. So you have a few choices. Find shops that restore old electronics and call them and ask if they have anyone who would asses your valves, or even better, if they're interested in just buying the whole lot of them as a lot. Or go on EBay and look for the particular numbers and see what they've been selling for.
Q: I have a Jupiter double horn. The thumb valve will randomly stick down and not want to come back up. It however only does this when I play a scale or am in the middle of a song, so when I ask the director or an instrument repair person to help, they think I'm crazy and see nothing wrong with it. Also, the first valve is slightly bent sideways towards the second valve. I got it used and it came like this. It is not horrible, but that makes it significantly slower than the other valves and sticks a LOT. All repair shops do is take my money and claim they've fixed it when they have done nothing. It is so frustrating. What should I do? And the oil doesn't help with either of these things, which is even MORE frustrating.
Open up the #4 valve cap and flood the top with valve oil, put the cap back on and turn the instrument over. Put valve oil in the crack where the valve comes out of the bottom of the valve case. This can be hard to see. Put some drops on every moving part of the valve action. I can remember the layout of that valve but I don't think you can shoot oil into the valve. Try all that I said above and see if that helps. Rotate and wiggle the valve between each step.
Q: I have three zone valves, two out of the three don't ignite the gas. Once I turn up the thermostat I see the lever on the zone valves move but no gas ignition. Only one of three works fine. Any leads? Thanks!
Located in most zone valves is a end switch. The end switch closes when the zone valve opens. It sends a signal to the AquaStat to bring on the boiler. The pump runs as soon as there is a call for heat on any zone. Now if the water temp in the boiler has reached its high limit than the boiler will not come on. It will wait until the temp drops in the boiler and then it will ignite. So watch it for a few minutes. The end switch or connections may be to blame if the boiler does not come on at all after a reasonable amount of time. The end switch does fail on occasion. Best bet is to call a professional if you continue to have problems
Q: its a vauxhall movara van and i need help im trying to found out wether the valves are broken all the springs are upright and all level , so does this mean there ok ? or not ... thanks
The valve can be bent or broken under the head. Just because it looks right up top only means the stems are OK. The stems are usually OK, even if the valves are bent and broken. If it's making horrible valve noises and you're not sure, it's probably got a bent valve. Only way to know without pulling the head is to do a compression test.
Q: I was wondering if the pressure relief valve can be vented right under the house or does it have to be ran to the outside of the house. Also is there another method such as a catch pan that I can employ? I live in Washington.
Most codes state that it must be vented to the outside.Check with your city code enforcer or county office.
Q: I go deer hunting with my dad and he has an artificial heart valve. It isn't too loud, but I can hear it about ten feet away if it's quiet enough. Is it possible that we haven't shot any deer yet because the deer can hear the valve and know to stay away?
I seriously doubt that the valve is the reason...even if the deer could hear it, they wouldn't know to connect the weird noise to a hunter...they'd be more likely to smell you.
Q: Ok so i am 16 years old, and i have Aortic stenosis, bicuspid aortic valve, aortic regurgitation and an Enlarged aorta. I am soon going to be getting an aortic valve replacement. I am just wondering what happens before and after the surgery and how long i will be in the hospital, how long in the ICU, what kind of tubes/machines will i need? any information will help. thanks :)
Mechanical valve will last for ever. But the red blood cells will be damaged and clot will be formed in the implanted mechanical valve. In order to prevent the formation of blood clot, the patient has to take warfarin (a blood thinner) for the rest of his/her life. If pig valve is used, there is no necessity to take the medicine (warfarin) for the rest of his/her life. But the tissue valve will function only for 15 years. Since you are too young, you have to opt for mechanical valve and to take the medicine for the rest of your life. Valve replacement is indicated for virtually all who can tolerate surgery. In younger patients, the patient's own pulmonic valve can be used, providing good durability; a bioprosthesis is then used to replace the pulmonic valve (Ross procedure). Most often, the aortic valve is replaced with a mechanical or bioprosthetic valve. You will stay in an intensive care unit for the first 2 or 3 days following the operation. Your heart functions will be monitored constantly. The average hospital stay is 1 - 2 weeks. Complete recovery will take a few weeks to several months, depending on your health before surgery.
Q: I have this air canister i want to attach to a homemade Airsoft gun. (please no comments or answers on that).The air canister has an opening on both ends. I thought for simplicity, put a filler valve on one end and a connection to the gun on the other.Exactly what kind of one way filer valve will i need, most of the ones i look at look like propane tank connections and those are for filling and dispensing into the system.

Q: My brother is 32 years old.He has an enlarged heart ,a murmur,high blood pressure and heart regurgitation.He may be having the valve replacement surgery.I was wondering if anyone has had these things wrong with them and had the valve surgery and did well afterwards.Any information would be very much appreciated.
No...but heart valve surgery is rather routine for all but the concerned relatives and patient who tend to worry.....people do very well with replacement heart valves.....
