What are gate valves used for?
Gate valves are used for high pressure services. Gate valves may have a union, bolted or screw-in bonnet. Another type of bonnet is a pressure seal bonnet.
Motorcycle uses to much oil?
Worn engine rings or valves Worn engine rings or valves
What are Disadvantage of diode valve?
the disadvantages are that over a period of time gate valves seize and become in operable. also the handles of gate valves corrode quickly and gate valves don't entirely close properly making it difficult to solder. Gate valves are used for positive shut off and Gate valves are not designed for throttling like a globe pattern type . Gate valve fail because the installer has no idea what these types of valves are intended to do such as main steam shut off's or water mains..If properly used and installed correctly these valves last over 100 years under extream conditions
What causes low compression?
Worn piston rings, Burned valves, Sticky valves,
What is the use and features of the Expanding gate valves?
Expanding gate valves are used in various industrial areas like isolation valves in power plants, ESD valves in production, block valves in process systems, high temperature valves in refineries, and pipeline valves in critical areas. These expanding gate valves manufactured by various manufacturers are available in all the sizes, pressure ranges, and trims used in piping systems requiring the positive shut off of liquid or gas. The expanding gate valves are full bore through conduit valves with rising stem and parallel expanding gate and segment for tight mechanical seal and positive shutoff, both upstream and downstream, and under both low and high differential pressure. An expanding gate valves should have the following features: Parallel expanding gate design creates positive mechanical seal across both seats, both upstream and downstream, with or without line pressure. Non-rising stem permits valve installation in pressure drop.

How do calculate the gate thickness for a parallel gate valves?
The ideal thickness will have no obstruction in flow, meaning that no friction will be lost.
What are the different designs of a gate valve?
There are numerous types of valves. Each has a specific function and usage and differs from the others. From seismic , to pressure they can be specialized or simple in function. A valves purpose is to allow, stop, or reduce flow of a substance thru a pipe. Most common valves on homes would be gate and ball valves. In order to learn which valves are best for your application, consult a professional. types below, that i can think of off the top of my head, there are more i am sure. -ball gate mixing pressure reducing butterfly cocks angle temperature seismic ansul backflow check
What type of valve is used to shut off a water line?
Gate valves used to be, now they are being superseded by ball valves.
What type of valve disc for gate valve?
They are usually ceramic disc's in gate valves , best thing is to buy the whole tap hat for it.
How do you adjust valves on 300 6 1978?
The valves on a Ford 300 straight six are not adjustable. If they are noisy you have worn valve train parts.
Can we used gate valve for steam supply manifold?
it depends on where you are installing it on the manifold, and what you will be using it for. Gate valves really only work well as either full open, or full closed valves. They are thought of as shut-off valves so if you wished to put one at the inlet of your manifold, that would work well. If you are looking to regulate the steam to different branches of a manifold, then you would be better off using globe valves for those locations. Globe valves are designed to throttle or regulate flow. If you try and use gate valves to throttle, you will not be happy with the results, and they will wear out and not fully close, when you need them to close.Hope that helps.Ron Powell BSME
