Q:trucuspid valve... pulmonary valve??
Inga, Valves are flap-like structures that allow blood to flow in one direction. The tricuspid valve is located between the right atrium and the right ventricle and prevents the back flow of blood as it is pumped from the right atrium to the right ventricle. The pulmonary valve is the structure in the pulmonary artery consisting of three flaps, which open and close during each heartbeat. The flaps keep blood from flowing back into the heart from the pulmonary artery which is the artery that supplies blood to the lungs. Hope this helps matador 89
Q:1995 Chevy V6 Blazer EGR valve?
If your problem EGR Valve is AC-Delco, it can be cleaned and will work like new and save you the cost of buying a new one. Also, I was told by a local auto-repair shop that EGR Valves have a LIFETIME Warranty... so if you have your receipt take it back for free replacement. If having to purchase a new one, Save Your Receipt. If your problem EGR Valve is aftermarket, replace it with a new AC-Delco. Aftermarket EGR Valves are crap and cleaning will not fix the problem. Same with fuel pump... install AC-Delco ONLY. 1995 Chevy Blazer 4.3

Q:Should I have this shutoff valve replaced?
An old saying I like is If it ain't broke, don't fix it!. Even though the packing nut appears to be cross-threaded, if there is no leak, I'd leave it alone. Washer connection stop valves seldom get used. They mostly just stay on, unless you have a washing machine breakdown. I'd just peek at it each washday. If it doesn't leak, I'd leave it be.
Q:Sticking Intake Valve?
Are you sure that the valve is sticking or is the carburetor flooding?
Q:Toilet shutoff (stop) valve problem?
PEB could be top yet my journey has shown that this type of water hammer is led to with the aid of the ballcock interior the bathroom. The fill mechanism interior the unit in simple terms starts off vibrating after a whilst. try this little try; Flush the bathroom and spot if the vibration takes place while the bathroom is in finished top off mode, (waft top down, a brilliant sort of water entering the tank) - or does the vibration take place while the tank is in simple terms approximately finished, (waft is beginning as much as close off the fill mechanism). you additionally can try with the aid of pushing down on the waft ever so particularly while the tank is done - you will probable hear the vibration at that element. base line - replace the ballcock and all might desire to be properly.

Q:What are Atrial valves?
You're incorrectly combining two parts of the human heart, atrium(atria) and valves. The human heart has four chambers, two superior ATRIA and two inferior ventricles. The atria are the receiving chambers and the ventricles are the discharging chambers. The pathway of blood through the human heart consists of a pulmonary circuit and a systemic circuit. Blood flows through the heart in one direction, from the atria to the ventricles, and out of the great arteries, or the aorta for example. This is done by four VALVES which are the tricuspid valve, the mitral valve, the aortic valve, and the pulmonary valve
Q:Control Valve?
A major improvement in the DWEER system has been the development of the LinX (LinearExchanger) valve, which was patented byShumway . This valve replaced eight two-way valves with asingle multi-port spool valve which simplifiedthe system, improved reliability, reducedmaintenance requirements and allowed for fastervalve switching, reducing the size (and thus cost)of the energy recovery vessels. DWEER systemsutilize long vessels which may be installed underthe membrane vessels. Atpresent, the largest available DWEER system has a capacity of 500 m³/h.
