Which valve is prefered to use for ammonia tanks a globe valve or a gate valve?
If the purpose of the valve is to modulate flow, a globe valve is preferable. If the valve is only on-off, a gate valve is preferable because of lower pressure drop when the valve is open. As wikipedia , A globe valve is a type of valve used for regulating flow in a pipeline, consisting of a movable disk-type element and a stationary ring seat in a generally spherical body. So i think it is a globe valve to use in steam pipeline.
Why should use globe valve in bypass line of control valve?
The purpose of the bypass and the globe valve would depend on the function of the system. The bypass might be used to allow a small amount of flow around the control valve to warm or purge the line prior to startup, or it might be there as a failsafe to prevent inadvertent total shutoff of the line by the control valve. In any case, a globe valve in the bypass line provides adjustability along with the ability to shutoff the bypass flow and Globe valve has following advantages. 1.Good shutoff capability 2. Moderate to good throttling capability 3. Shorter stroke (compared to a gate valve) 4. Available in tee, wye, and angle patterns, each offering unique capabilities 5. Easy to machine or resurface the seats 6. With disc not attached to the stem, valve can be used as a stop-check valve.
How do you replace cast iron flange?
You have to take the lead and packing out that is holding the flange in the next piece of pipe. If your flange is broke where the toilet bolts go, this is very common. There is a repair available for this. It consists of two curved pieces of metal that are about 1/3 of the circumference of the flange. They go under the flange and give you a new place to put the bolt. They are a lot easier to use than replacing the whole flange.
Who invented faucet?
The faucet use to be called a valve. The valve has been a way of shutting on/off water flow all the way back to the Egyptians, Romans and Greeks. The Romans helped to better the system by running water into buildings. In 1870 JH Davis got a patent on a globe valve.
What is the difference in blank and blind flanges?
Blind flange is put at the end of pipe or at the junction that would possibly be a future expansion into that direction. Piping is easier to drill or weld at the construction stage. Once it was in use, drilling or welding will need prolong cleaning especially when the fluid transferred is combustible. For the mean of future extension, either the blind or valve would be used to seal the end.
What valve is the preferred valve to use in throttling a gate valve or globe valve?
Never ever use a Gate type of valve for throttling ONLY a globe pattern is designed for this purpose and a needle valve

What are flange valves and why are they useful?
flange valves are useful because lets say in your sink the faucet is leaking you can use the flange valve to stop the water and repair the sink without having to turn the water for your whole house off.
What is the plumbing code on installing a globe valve under ground?
NO plumbing code would dare say use a globe valve under ground that has no access to service it?
Can a ball valve be used to throttle flow?
no it can't , valves you can use are a prv pressure reducing valve or a globe or flow valve
Why does the water run so loud from my basin tap?
excessive velocity use a globe valve to throttle the volume
Where is a ball valve used?
Where one would use either a gate or globe pattern type A ball valve is used to turn water , gas or oil on and off.
How is working motorized operated valve?
motor is used as a actuator here. we can use globe,ball,butterfly type valves
Can you use forged flange with cast flange?
Normally whether use the forged flange or cast flange depends on the design code, material, pressure, temperature, stress strength and medium of the piping system. It has been decided since the beginning of the design. If forged flange is chosen, it is very dangerous for you to use cast flange due to its much lower strength and other mechanical&chemical performance. If cast flange is chosen, it is not sensible to change it to forged flange because of the high cost. Visit Hebei Metals Industrial Limited website for more information about the forged flange. www.metalsflange.com

High idle on a 2000 Malibu?
remove iac and clean it. ( idle air control ). the best way to clean it is to use a old tooth brush or similar. do not emerse in any liquid. and do not push on end of valve, it will mess the idle setting up! you can use carb cleaner or electrcal cleaner for valve. let it dry before replacing it. on the 3.1 engine, it the valve should be--1-1/8 from tip of valve to mounting flange.
How do you repair a leaking globe valve?
A ceramic globe valve operates on a very simple and reliable design. For this reason, there are few points where failure or leaking can occur. When a leak does develop, repairs are limited to one of three areas: the seating, gasket or packing. If you must take apart the globe valve to repair any of the three areas, consider replacing all three components, even if they are not currently leaking. Diagnose the problem. If the globe valve allows water to pass through it when it is fully closed, the problem is in the seating. If water leaks from the point where the stem (handle) enters the bonnet, the problem is the packing. If the leak is at the joint where the body and bonnet connect, the problem is the gasket. Turn off the water supply at the nearest shut-off valve. Open the globe valve and allow any residual pressure to be released. Use a wrench to loosen the bolts where the body and bonnet come together. Depending on the size of your globe valve, there could be just two bolts, or several. Carefully insert the screwdriver into the seam just below the bonnet and pry it away from the body of the valve.
