Manual ball valve

Q: What is the International Standard or other acceptable calculation or table for determine the air supply of pneumatic actuator in shutdown valve 6 to 24.Desired answer will be air flow in SCFM.Thank you.: Shut down valves I've worked with haven't had an 'Air Flow' for their operation. For the smaller valves, they consist of diaphragm operated valves either held open or closed by pneumatic pressure. The air supply at 25psi to give a diaphragm holding pressure of 15 psi, is via a solenoid valve which dumps the air pressure to either open or close the valve depending upon its function. (That of isolating a system or relieving pressure). The solenoid is actuated by a signal from the shut-down system, and the valve is a 3-way unit which isolates the supply air and vents the pressure off the diaphragm. Other SDV's in my experience, are operated in a similar way but are much larger and are operated by a pneumatic air cylinder and piston with air supplied at 100 psi. Others encountered are ... MOV's...Motor Operated Valves that can be automatically operated from the shutdown system, or Operated Remotely from a safe distance (ROV's).

Q: I don't have one single water shutoff valve in my house that will shut anything off completely. It looks fairly easy to repack them, and I have the tools, and there are instructions all over the internet. The question I have for the experienced among you is what packing material do I use? I have heard graphite thread and teflon tape and even joint compound.Is one better than the other? Easier to use?Also, if there are any pitfalls I should know about before I undertake this, please advise.Thanks in advance!: For stopping leeks use teflon tape to lub your valves use plumbers grease it s good idea to have a tube around not expencive

Q: Does a faulty pcv valve (Positive Crankcase Ventilation valve) cause excessive exhaust smoke ?: most likely it will knock as well

Q: i just replaced the head gaskets on my 1991 Acura Legend and When i put the timing belt on somehow it slipped and came loose I than tried to start it(not knowing it came loose) and it cranked hard and strong but no start. I just retimed the engine and put new timing belt set on it and when i started it the car blows grayish blackish smoke from the exhaust and has a really crazy idle. Could the valves be bent: The 1991 Acura Legend 3.2 is listed as an interference engine. (Other models that year if any probably not). If it is an interference engine the valves may have been bent. But asking y/a is not the answer. What you need is a compression test. If the compression is alright then there could still be damage but not in immediate need of repair. Black smoke means incomplete combustion.

Q: So it always seems that when I see the jet and foot valve out of a well there's a drop tube between the jet and foot valve. My question concerns this drop tube- is it necessary? I've got a leak somewhere, replaced the foot valve and still have a leak. I'm inclined to get rid of the old drop tube, it's crusty and likely to be the source of leaks either now or in the future. any reason to not just plumb the foot valve directly to the jet? Thank you kindly for useful information.: This drop tube is the suction line. This tube will always be below the water level in the well. I would talk to a competent water well company and get their recommendations. Regards, Dale

Q: Hey quick Q, I heard somewhere that you could degrease the the reed valve? I love cleaning up my CR250 as much as I can. I just want to know if this is done, and if you could, tell me where I'm supposed to clean.Thanks.: Spray degreaser down the air intake-that should fix it.

Q: my EGR valve has gone on my Vauxhall Vectra 2.0 DI LS, 1998, 5 DOOR HATCHBACK, so i am getting a new one next week, what i want to know is, is it an easy job to replace them if so how do i do it? or is it better just to let a garage do the job?: Easy. Just google it and it will tell you how. It will take a minute to change.

Q: I started out playing trombone in middle school, then switched to euphonium as my main instrument. (I still play trombone for marching and jazz band, but I'm a little better at euphonium.) That being said, should I get rotary valve trombone or the one with axial flow? I only have a student trombone right now... And I have a professional Besson euphonium.: Rotary Valve Trombone

Q: Friends,is there anyone know about LinX(Linear Exchage)Valve,how they work.thanks in advance: A valve is a device that regulates the flow of substances (either gases, fluidized solids, slurries, or liquids) by opening, closing, or partially obstructing various passageways. Valves are technically pipe fittings, but usually are discussed separately. Valves are used in a variety of applications including industrial, military, commercial, residential, transportation. Plumbing valves are the most obvious in everyday life, but many more are used. Many valves are controlled manually with a handle attached to the valve stem. If the handle is turned a quarter of a full turn (90°) between operating positions, the valve is called a quarter-turn valve. Butterfly valves, ball valves, and plug valves are often quarter-turn valves. Valves can also be controlled by devices called actuators attached to the stem. They can be electromechanical actuators such as an electric motor or solenoid, pneumatic actuators which are controlled by air pressure, or hydraulic actuators which are controlled by the pressure of a liquid such as oil or water. Actuators can be used for the purposes of automatic control such as in washing machine cycles, remote control such as the use of a centralized control room, or because manual control is too difficult; for example, the valve is huge. Pneumatic actuators and hydraulic actuators need pressurized air or liquid lines to supply the actuator: an inlet line and an outlet line. Pilot valves are valves which are used to control other valves. Pilot valves in the actuator lines control the supply of air or liquid going to the actuators. The fill valve in a commode water tank is a liquid level-actuated valve. When a high water level is reached, a mechanism shuts the valve which fills the tank. In some valve designs, the pressure of the flow fluid itself or pressure difference of the flow fluid between the ports automatically controls flow through the valve. In an open valve, fluid flows in a direction from higher pressure to lower pressure.

Q: In place of actual valve oil, can I use WD40? How about baby oil? Are there any household products which work?: A bottle of valve oil only costs $3-4, so next time you go to the music store, buy two bottles. Then you'll be set for a long time.
