Product Description:

 



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:What is a Remote Operated valve ?
Rov Valve
Q:how do you repack an OS&Y valve?
For most valves, replacing the packing can be done without shutting down the water system. The first step is to back seat the valve. Back seating will occur when the valve is fully opened, and will temporarily seal the leak around the stem. You simply open the valve completely with about 50-100ft-lb of pressure. Once the leaking has stopped, you can remove the packing bolts and nuts on the packing gland. Slide the packing gland up the stem and you will have access to the packing. You may need a packing hook, which is a flexible corkscrew tool, to help remove the old packing. Once you have removed the old packing you will want to repack the valve with new packing by wrapping it around the stem and pushing it down into the valve body. After the new packing has been replaced, it may need to be compressed a little so that the packing gland can be reinstalled. This can be done using two pieces of all-thread rod. Cut both all-thread rods to 6 inches long, making sure to use the same diameter all-thread rod as your packing bolts. Place the all-thread rod through the packing gland and tighten the nuts onto the all-thread rod to compact the packing in the valve. Next, remove the all-thread rod and replace with the bolts. Turn the hand wheel, so the valve is about half way open. Finally, tighten the nuts evenly until all leakage around the stem stops. You may need to exercise the valve a few times to make sure there are no leaks around the stem. Be careful not to over tighten the gland because it can crack and there is no reason to compress the packing more than is needed to stop the leak.
Q:***10 points**** Which set of valves closes when the ventricles contract and relax?
Atrioventricular valves close when it relaxes and the lunar valves close when it contracts
Q:Cost to replace/fix valves?
To replace valves would probably run around $500. Plus they will probably charge you about 8-10 hours in labor to remove/reinstall the head from the block at about $90-$100 an hour. Not to mention the replacement of gaskets which could be around $100-150 So it can get pricey. I would budget for about a $1750-$2000 worst case to have this fixed. I am sure this isn't what you want to hear but once you start getting into the internals of the engine, things are going to get pricey.
Q:Can I use sewing machine oil instead of rotor oil on my French Horn Valves?
If you don't get a good answer here, try reposting your question in Arts Humanities / Performing Arts - a lot of instrumentalists hang out there.
Q:aortic valve with 98% gradient can be cured by body revive?
Can be cured by valve replacement... alternatively, if you can't/won't go through open heart surgery then you may be able to get valvuloplasty. A balloon is used to stretch the valve open. This does not last nearly as long as replacement, but avoids surgery. A third alternative would be to contact one of the percutaneous valve REPLACEMENT centers (Mayo, Cleveland Clinic, Columbia). This is an experimental procedure which replaces the valve using catheters instead of surgery. Advice offered here is not meant to be a replacement for proper evaluation and examination by a qualified medical professional and should not be construed as such.
Q:95 cougar xr7 EGR valve?
How do you know that you have a bad valve? Are you just going by the code,or did you have it checked by a tech.? I have replaced very few valves.If you have a v vacuum pump you can check your egr valve. Apply vacuum an it should hold. Now with engine running apply vacuum does the engine stubble or stall? If the valve holds vacuum its good, an if engine stubble's the ports are not plugged. If all that checks out good the problem is most likely the DPFE sensor. If i were there with a scanner i could tell you exactly what wrong.Its not impossible to change the valve take your time an be patient.
Q:replacing pressure reducing valve?
The cost you quoted seems a bit high to me. Mine didn't cost anywhere near that amount in East Texas. A pressure reducing valve acts like a check valve when there is no flow. That is it closes as the pressure rises when you are not using any water. In this condition, the hot water heater can raise the pressure even higher since there is no place for the expanding water to go. That is the reason for the expansion tank. Without the expansion tank the pressure relief valve on the hot water heater can relieve unnecessarily or weep a bit.
Q:PCV Valve Information?
most cars the pcv valve is easily replaced it is usually on the valve cover if you can see it you should be able to replace it if you cant see it it may be burried in the engine somewhere pcv stands for possative crankcase ventilation it keeps the pressure out of the crank case.(thats were the oil is circulated0
Q:Dodge Valve Cover Gasket?
to do it yourself, you need to have a workshop manual (cost $24.00) wrenches (cost $15.00) screwdrivers ( cost $12.00) Gasket (cost $8.50) Liquid gasket (cost $4.00) Hand Cleaner (cost $3.95) Total $67.45 plus tax Having someone else do it for you ( priceless)
