1. Structure of WKM Expanding Gate Valve Description
1) Metal-to-metal sealing (gate-to-seat and seat-to-body).
2) Expanding gate design creates a positive mechanical seal across the seats, with or without line pressure.
3) Full-bore, through-conduit gate-to-seat seal maximizes valve life by virtually eliminating turbulence and pressure drop.
4) Gate skirts reduce loss of body lubricants.
5) Low running stress enhances life of the gate-to-seat interface.
6) Upper/lower roller thrust bearings are isolated from well fluid, minimizing torque.
7) Stem packing can be re-energized with valve under pressure.
8) Non-rising stem permits valve installation in closer quarters.
9) Seats, gates, stem, and other working parts are field replaceable.

- Q: Does a faulty pcv valve (Positive Crankcase Ventilation valve) cause excessive exhaust smoke ?
- Yes. This would definitely cause excess smoke, probably white in color. If the pcv valve is bad, it's probably leaking water into your oil, and oil into your cylinders, thus your engine is burning oil. This is an extremely cheap and easy fix. Make sure that when you change the pcv valve, you change the pvc valve grommet as well (the little black seal around the valve). Also, be extremely careful not to crack any plastic from the pcv valve or the grommet, because pieces of the plastic could fall into your intake manifold, and then you have to remove the intake manifold cover and that can become a pain in the a**.
- Q: How would your car run if u did not have one on it? Do u really need to have a pcv valve? I have a 1994 Ford Econoline
- PCV Positive CrankCase Ventilation, its designed to vent out the gases that leak past the piston into the crankcase. The valve is more for pollution reduction as the vented gases are recirculated back in for combustion, So you don't need it but its nice to keep the air clean,
- Q: HowdyWas taking apart a screw down NR valve and screw lift valve and noticed the spindles were made out of different materials. Brass and Steel.I am aware that brass is non corrosive but why use steel in the other valve? Is it due to their operation, do they come or not come in contact with fluids? Is one cheaper than the other?The screw lift globe valve had a steel spindle and the screw down nr glove valve had a brass spindle.Also, if anyone knows what materials are used in the valve lid and seat are made of.Any ideas?Cheers
- *In steam service , steam flashing is one of the factor which erode the spindle ( say valve stem) *The stem serves as a connector from the actuator to the inside of the valve and transmits this actuation force. Stems are either smooth for actuator controlled valves or threaded for manual valves. The smooth stems are surrounded by packing material to prevent leaking material from the valve. This packing is a wearable material and will have to be replaced during maintenance. With a smooth stem the ends are threaded to allow connection to the plug and the actuator. The stem must not only withstand a large amount of compression force during valve closure, but also have high tensile strength during valve opening. In addition, the stem must be very straight, or have low run out, in order to ensure good valve closure. This minimum run out also minimizes wear of the packing contained in the bonnet, which provides the seal against leakage. The stem may be provided with a shroud over the packing nut to prevent foreign bodies entering the packing material, which would accelerate wear. Disc material: Cast Iron or Ductile Iron Disc Aluminum-bronze Disc Stainless Steel Disc Nickel-plated Ductile Iron Lid material: engineering plastics, Cast Iron. Seat material[hard/soft]: Seats can be integral to the valve body, that is hard metal or plastic. *Hard seat: Hardened steel,Cast Iron,EN-52 forging steel Valve Seats are made from Chrome Alloy Steel which has a high wear resistance at high temperature. Nearly all metal seated valves leak, even though some leaks are extremely small. *Soft seats can be fitted to the valve body and made of materials such as PTFE or various elastomers such as NBR, EPDM, FKM. Each of these soft materials is limited by temperature (rough maximum temperatures are listed below) NBR 80 °C EPDM 120 °C FKM 170 °C PTFE 200 °C
- Q: Can someone please help me on this anatomy question:Describe the physical similarities and differences in the structure of the AV valves and the semilunar valves.Thanks
- av valves are anchored to the wall of the ventricle by chordae tendinae, multicusped valves while semilunar valves do not have chordae tendinae, but are more similar to valves in veins. positioned on the pulmonary artery and the aorta both have the same function of prevent backflow of blood
- Q: I really like the sound that a blow-off valve makes when they are in audi tts. So I was wondering if I got one for my '02 225hp Audi tt if it would damage the engine in any way. I have read that diverter valves are better, but I want the sound of the blow-off valve. Also any recommendations on blow-off/diverter valves would be great.
- Blow off valves are nice, but they aren't terribly good for your car. The main problem is that when the turbo isn't running, that open valve will suck unfiltered air into the engine and can seriously damage it. Blow offs are also pretty inefficient as you lose a good portion of the air in your turbo system. The best thing you can do is just get a good Forge diverter valve. Well made, looks nice, and will add a pretty decent amount of performance.
- Q: I went to turn the water off with the shut-off valve so that I could do some work on the toilet tank (replacing old and leaky fill valve) but the water won't shut off. I'm assuming that I'll need to replace the shut-off valve itself but could anything else be causing the problem? The funny thing is, the leaky fill valve that I wanted to replace has now stopped hissing and leaking and the tank seemingly fills fine. But of course the water can't be turned off completely.Just wanted to check make sure that there aren't anything else I should do or consider before I went off to replace the shut-off valve.Thanks
- Youdont give much info here.Does the ballcock come back up after flushing, if it doesnt you can bend it gently upwards, so that the piece connected to it that stops off the water, works better.If its ok then best buy a new ballcock with the valve attached.The way these work is all to do with the floating ball at end of ballcock .When the ball is on top of the water , then the other end stops more water coming in.These are usually easy to sort out.
- Q: I think they need to be taught how to count. Honesty... Half-Life, Half-Life 2, Half-Life 2: Episode One, Half-Life 2: Episode Two... Where the hell is 3 already?
- Unfortunately Gabe was never very good at math hence no Ep.3 or any other game to bear the number 3 ex. L4D, Team Fortress and Portal stop at 2 as well. On a serious note though, I am completely fine with Valve taking their time if the end result will be a quality game. Would you rather Valve rush development for Ep3 and have a mediocre game like so many other developers/publisher do? A delayed game is eventually good, a bad game is bad forever (well with exception for Duke Nukem forever but then again not all 15 years went into developing the end result) . If Valve needs to take it time to get the story right then so be it, we don't want another ME3 mess. Alex H. Where did you get your source from? Valve has not even muttered a single word of making a third L4D game let alone announce one.
- Q: I've never replaced a shut off valve before but am wondering if there are any tricks in freeing up a stuck valve that wont close. Can this be done so I don't have to call anybody?
- turn off water to house, if your valve has a nut behind handle that has threads on inside of nut ie brasscraft style, you can go to store and buy new valve and replace stem. If pipe comes out of wall (angle stop) get that one, if comes out of floor (straight stop) get that one. remove new stem and old stem and switch. If nut behind handle has threads on outside of nut, then you must replace valve. ( you have to remove nut to see where threads are ( i don't but you might) depending on what type of pipe you have is what new valve you will need and also how close to wall or floor is how to attack problem tre..706yahoo 4 any more help
- Q: I drive a 08 lancer and I want to add a SRI. Can I produce the blow off valve sound like a turbo?
- lololol (not at question just at other responses). NO u can't dude, a blow off valve is a pressure release system for turbos, Its purpose is to prevent compressor surge, its is a vacuum-actuated valve designed to release pressure in the intake system of a turbocharged car when the throttle is lifted or closed, any built up pressure from the impeller once the throttle is lifted the blow off valve releases the air to the atmosphere, you can buy different trumpets for a different sounds effect, engines that are have a turbo but no blow off valve have what is called a diverter valve that recycles the air pressure back into the air intake... If you mean a Fujita SRI exhaust system then it will just have a nicer deep tone, not a harsh high-pitched sound like the other rice burner exhaust systems..
- Q: One of my valves leaks a small amount of water through the valve and into the water line. why would it leak and what do i have to do to fix it. the valve is a rain jet valve. i would like to fix it without having to remove it from the valve box. inside the valve box there are 8 valves and they are glued in and i dont want to have to remove all of the valves and box.
- It depends on the type of leak. I recently had a leak (mea culpa four-pronged fork) and I was able to fix it by mounting an original hose clamp around it. If it is big you can use more than one hose clamp and perhaps a sheet of rubber or a part of the original hose in combination.
