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

Q:hello I am having trouble inflating my back wheel tube. so i guess i will just tell you what happened. well i came back from the bike shop with a presta valve adapter and i put it on my tube. it fills up too near full psi but just after a ride around the block it is flat. i have no idea why. please help me! also its a mavic tube 700 x 23, vittoria rubino pro 700 x 23 tire, and a vuelta xrp 17 deep v back wheel. thanks!
You have a slow leak. You need to pull the tube and patch the hole or replace the tube.
Q:Hi My sons car has alloy wheels, and metal valve stems, there is a tiny leak between the valve stam and the alloy on one wheel, we are struggling to get anyone to repair at a reasonable cost. Would tyre weld make a permanent repair?. Some tyre specialists won't touch the wheel, one other wants to drill out the stem put in another, which sounds a bit drastic. Any other ideas?, is it feasible to get the metal valve stem replaced by a rubber version?. Apparently the metal ones get curbed and then start to leak.
The leak is caused by corrosion of the alloy wheel in the hole that the metal valve stem goes through. You might try to let the air out and loosen the nut on the valve stem and spray penetrating oil on the o-ring which is on the base of the valve stem and is what holds the air in. Turn the stem back and forth a bit to mave the corrosion and then respray the o-ring. Tighten the stem nut, inflate the tire to 35 lbs. and spray a bit of soapy water on the stem to check for leaks. If it still leaks you will need to remove the tire and valve stem,clean the hole and surrounding area inside the rim and clean the valve stem and replace the o-ring. If the valve stem is a pressure sensor type for the tire air pressure monitoring system you may need to reprogram it. Only use plastic caps on the valve stem. Metal ones corrode on the stem and wreck them and never come off.
Q:if safe, at what age should a woman with mitral valve prolapse be pregnant?
My daughter was diagnosed with MVP at age 14. She has had 5 pregnancies, 1 miscarriage and 4 deliveries. That's 4 deliveries in less than 5 years. The obvious answer here is to talk to the OB that will deliver you to have your particular case evaluated since we don't know all the details.
Q:It started leaking slowly so I opened the release valve for about 20 secs than closed it back to see if that would help, but now it leaks even more. So I had to shut off the water that's coming into the water heater and know I can't use the hot water in my house. Can someone help me please!!!!
you will have to get it repalced.after they get old the spring inside starts to get weak.It will only get worst!Do not do a patch job,its not worth it.
Q:The valve on my radiator has numbers on it to determine the amount of air/steam leaving the heating system. what number should i put it on and how would i determine it
I would think the easiest way would be to put a thermometer on the radiator (with the bulb in the air flow), turn the heat on to one setting and record the temperatures each half hour for about 4 hours. Then, turn the adjustment to a higher (or lower) number and repeat that. That way, you'd know which way to turn to set it. Of course, the level at which you'd be comfortable would be found by trying different settings. Assuming the adustment is a valve, valves in the USA will open by turning counter-clockwise. Closing is, of course, clockwise. Hope that helps. EDIT: I received your email - I don't mind at all! OK, so you have only one valve for all the radiators. Without knowing anything else, I'd say you just removed the part called the bonnet (the upper half of a valve). It shouldn't matter which number it's set on if it's reinstalled correctly. When a valve is removed, the best way to put back is to open it slightly (turn counterclockwise to a low number), then reinstall the bonnet. Once it's back in, it should work like normal. If that doesn't work, perhaps you can get a plumber or a local handyman to check it. As to the upper ones being airlocked, it really sounds like there is a blockage in the supply line. I am assuming this is steam-heat radiator that is supplied by a boiler-type heating unit?
Q:So i finaly got my check valve and my airstone. The airstone is actually a flat round airstone and is 5 inches in diameter to be in my 10gallon. Is it to big? though i have a tetra whisper air pump for 10-30g.And how do i place the check valve? Do i put it closer to the tank or closer to the pump? (just to make sure since i heard so many different ways people put it). Or does it even matter?And lastly, do i put the OUT side of the check valve facing towards the tank or the pump?Thanks! after this im ready to install it!
The airstone is not too big, unless it causes the water to bubble right out of the tank. Then you will need a valve to divert the excess air to an unused air line. If the airline is already cut, just put the check valve wherever the airline ends. If it's not cut you can put it anywhere. The arrow on the check valve should point toward the aquarium. If it says IN and OUT, then the OUT is on the aquarium side. If you want to test it to be sure, blow in one end of the valve. You can't blow air into the side that connects to the aquarium. Be sure there is a drip loop in the air pump electrical cord. If water were to somehow get in the air pump or drip on it, water might follow down the outside of the electrical cord and go into the the wall outlet. To make sure that doesn't happen be sure the cord is looped down lower than the outlet and then loops back up before it's plugged in. Get a second airstone any time in the next few weeks. About once a month, trade airstones, putting the recently used one into a jar with white vinegar. A week or so of soaking will unclog the airstone so that it can be used again several times before needing to be discarded. If you do have excess air, I find that running a piece of airline tubing to a spot away from sight and putting a short piece of pipe cleaner in the far end will muffle the hissing sound of the excess air.
Q:This trumpet has been in storage in its casing untouched for about 5 years. I took it out and tried to play it but only air comes out and no sound. The 2nd and 3rd valves are hard to push down. What do I do to fix it? Thanks!
its your lips...lol you/I can make a trumpet sound off with just the mouthpiece alone.... try again
Q:primary function of a valve position?
Are you asking about a valve positioner? If so, then a positioner is a device that measures the amount a valve is open or closed and then adjusts the motive force to be sure the valve is in the position the controller calls for. These are typically use in cases of very high differential pressure or where the valve actuator may be under sized or marginal.
Q:Specifically, what is the mechanism which leads to pressure drops in expansion valves?
THERMOSTATIC EXPANSION VALVE A temperature-regulated valve that controls the amount of restriction to refrigerant flow between the receiver/drier and evaporator. Like the Fixed Orifice Tube, the Expansion Valve is the boundary between the High and Low sides of the refrigerant system. Unlike the Fixed Orifice, the Expansion Valve can regulate the flow of liquid refrigerant to the evaporator to either increase or decrease evaporator cooling based on the temperature of the refrigerant tube at the evaporator outlet. In vapour compression ref. cycle,The condensed liquid refrigerant, in the thermodynamic state known as a saturated liquid, is next routed through an expansion valve where it undergoes an abrupt reduction in pressure. That pressure reduction results in the adiabatic flash evaporation of a part of the liquid refrigerant. The auto-refrigeration effect of the adiabatic flash evaporation lowers the temperature of the liquid and vapor refrigerant mixture to where it is colder than the temperature of the enclosed space to be refrigerated.
