5.FAQ
1. What's are the characteristics of gate valve?
The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is desired. The gate faces can form a wedge shape or they can be parallel.
2. What is the work principle of gate valve ？
The gate faces can form a wedge shape or they can be parallel. Gate valves are primarily used to permit or prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow, unless they are specifically designed for that purpose. Because of their ability to cut through liquids, gate valves are often used in the petroleum industry.
3. What is the structure?
Bonnets provide leakproof closure for the valve body. Gate valves may have a screw-in, union, or bolted bonnet. Screw-in bonnet is the simplest, offering a durable, pressure-tight seal. Union bonnet is suitable for applications requiring frequent inspection and cleaning. It also gives the body added strength. Bolted bonnet is used for larger valves and higher pressure applications.
- Q: Into the wall basin faucet from the basin is the height of how much
- In the wall faucet precautions, please confirm the water pressure between 0.5 ~ 5kgf / cm 2 before installation. Please open the water before installation, remove the impurities in the pipeline.
- Q: What is the use of the hole below the basin faucet, on the basin

- Q: With a set of taps on the stone basin

- Q: This is the kitchen faucet, how can this move elbow removed? I can not afford to spin up to mention
- Can not be split, this faucet is one, can not only change part. To change the new words, we must first angle valve water off, and then connect the two valves connected to the valve release, and then from the basin below the wrench with a wrench. The whole leader came out. Or more trouble.

- Q: I just wanted to replace my kitchen sink but now that we have it in my cold water hose wont fit into the cold water valve.. they are both female ends. is there an adaptor i can use? do i have to replace the valve with a valve that has the right connection? and lastly what are these parts all called so i wont look like an idiot at the hardware store. thatnks for the help every one!
- Well, the first thing the hardware person is gonna ask is "What kind of plumbing do you have?" (Copper, plastic, iron?) If the two female ends you have are of the same type (1/2" NPT, for example -- NPT standing for National Pipe Thread, and the 1/2" referring to the "nominal" inside diameter of the pipe, which is actually considerably larger), then it's a simple fix: Get a short 1/2" galvanized iron "nipple" (which, despite its name, has two threaded male ends), and that should go between the two female connectors and solve the problem. If the threads don't match on one side or the other, you'll need an adapter, which the hardware store can provide. If your valve is functional, you shouldn't have to replace it. Be sure to use teflon tape on the threads: As you're facing one of the male ends, tightly wrap a strip of the tape clockwise two full laps around the threads. (By wrapping it clockwise, the twisting of the female fitting onto it won't undo the tape.) The teflon tape not only fills any flaws in the metal surfaces; it also lubricates the joint so you can get it good and tight. PVC plastic pipe generally has NPT fittings for attaching fixtures; copper might have the same, or have "flare" or "compression" connections. Galvanized iron pipe always is fitted with NPT threads, and 1/2" is most common for kitchen and bathroom. PS: I just now saw your photos, which weren't yet posted when I started writing this. The pictures are too small for me to be sure what you have there, but maybe the problem is just that you have two connector tubes! Take one of 'em off at the other end, and attach the free end of the other one there. In selecting which one to detach, the one coming from the plumbing is probably far easier to access; the one going up to the faucet would require a basin wrench -- not a fun tool to use -- and a flashlight, and three hands! Congratulations on doing it yourself!
- Q: Kitchen faucet around turn up not working, what good way?
- Waterlogging deposit and the original lubricating air drying caused by increased resistance to rotation. Solution: First, tighten the leading screw (in the bottom of the sink table). Second, along the rotation of the mouth around the wiping of edible oil repeated rotation. Third, the flexibility to wipe the oil can be.
