- Q:My Rodeo 96 has a P0440 code (Evaporative Emissions Control System problem). I have visually inspected the hoses on the engine; double-checked the gas cap is tight; but have not looked at the fuel tank sensors and connections. I've noticed that the EVAP canister purge valve solenoid is switching non-stop (click-click-click noise without stopping). Is it the expected behavior?
- I have seen many of the Rodeo's purge valves malfunction causing rough idle and that clicking coming from the valve. It is not normal behavior for that purge valve. Double check all hoses for any hair line cracks, they tend to crack on the bottom side alot. Otherwise replace the purge valve it make a huge differnce in the vehicles idle and performance. Also a intake cleaning service helps quite a bit too, most lube centers and shops can do it for about 50-60$. That cleans all the carbon out of your intake plenum, port runners, valves. It may help the valve to stop malfunctioning also, have seen that service clear all codes and bring back lost power and rough idles clear up.
- Q:I'm taking a pipe fitting class and I can not find witch valve had the most restriction.
- I okorder /
- Q:I have a 1987 Chevy Blazer with a 5.7 liter 350 engine. Where is the PCV valve located on it?
- My guess would be in one of your valve covers,Look for the black hose hooked to it.
- Q:What are the types of control valves used in the oil industry and how are they applied.
- There are other manual control valves and on/off automatic valves that are used a various places for remote or emergency control. These can be globe, gate, ball, plug or butterfly valves. They can be actuated by pneumatics, hydraulics or electric power.
- 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:I have a '98 Dodge Caravan 3.0 and the valve cover gasket is bad. How do I replace it?
- take the bolts off pull off old cover and do the same with new cover!
- Q:My Dr placed me in the care of a cardiologist who ran some test and an echo scan reports i have a leaking valve but she failed to tell me which one and i failed to even think to ask. What are the results of leaking heart valves? I asked my mother and she says each one has a different result. What are they? Any help would be great. thanks.
- i exchange into an open coronary heart RN. we frequently operated on people for the 2nd time, often desiring valve replacements. an consumer-friendly hassle after a 2nd time around open coronary heart surgical treatment is bleeding. the 1st 12 hours is extreme. countless those victims pull by using and do only extreme high quality. stable fulfillment with your Dad.
- Q:Offcourse temp control valve controls temp, and pressure control valve controls pressure....and so on. I am wondering, what are the mechnical differences in the valves body and how are they operated in terms of process control.
- In principle all valves are flow control valves. What changes is the variable they are controlling. A temperature control valve controls a flow to heat or cool another fluid. A pressure control valve, controls a flow to maintain the pressure in a vessel. As pointed earlier, valves can be self contained, i.e., the sensor is part of the control mechanism, usually a diaprhagm which moves the valve stem. and a spring to adjust a set point. Or, they can be pneumatic or electronic, in which case there is an external power source, transducer and controller to adjust set point, gain, reset and rate. This gives additional flexibility, if needed, depending on the process to be controlled. .
- Q:Okay, I got a 347 stroker and I noticed a spot that was leaking under one of my valve cover gaskets. So I went ahead and bought new gaskets. But before I replaced the gaskets I noticed that my valve cover bolts wasn't tight. So I basically went out for nothing and get new gaskets. Anyways since I couldnt return them, I went ahead and changed the gaskets. And I tightened all of them pretty tight. And I noticed that I still have an oil leak at the same valve cover gasket at the same place. Why is this? I also used cork gaskets, did I tighten them too hard? How hard should you torque valve cover bolts/
- cork gaskets have to swell use rv gasketseal around bolts and corners
- Q:what does mild sclerosis of aortic valve means? Why does it happens and what is its curethanks
- It means you have some plaque build up in ur aorta. causes are bad diet or gentics. change of diet can help
