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: Model 28 BS 12.5 HP engine intake valve sticks. Please advise.When under a full load like tall grass, it runs great, but when the load is not as heavy, the intake valve sticks open, spewing gas back through the carb and mis-firing.: Are you sure that the valve is sticking or is the carburetor flooding?

Q: where is the bleed valve in a 97 taurus????thank you: On virtually every modern car radiator it is at the bottom of the radiator on the engine side.

Q: Com wires attached to com and all individual valve wires are attached. The valves work manually( turn on by hand), I open the valve to allow the box to take over and the sprinklers run. Is this just residual water in the lines??: I would test the leads inside the control box first... You will have to run the controls manually to troubleshoot the problem. Get a voltage meter to test for the 24 volts at the transformer connections inside the box... If you do not have the 24 volts then the problem will be the transformer. If you have the correct voltage from the transformer then you can test each of the station terminals to common. Test through each station to see if you have 24 volts at each station terminal, but you may have to remove the wires off to test. If you do not have power coming from each station… then the problem will be the rain bird control. The next step would be testing the wires… If you reconnect the wires… test just prior at each valve location to see if you have the 24 volts between the common and each station wire… if you can prove out that there is 24 volts at this location then you’re down to the final testing. Reconnect the valves – one side to the common and the other to each station wire… Getting the power (24v) to the valve should have cleared your problem. Good Luck… Running the valves manually will not affect the operation of the rainbird control... but with my rainbird valves.. you can shut off the valves completely and disable the electrical controls of the valve... make sure that you have not closed the valve off manually preventing the electrical side... a problem with rainbird controls. This does not have anything to do with residual water in the lines... I would test this side first before you get into the electrical side... could save you a lot of time.

Q: I just got my water pump replaced on my Peerless boiler. Now my backflow valve is always dripping. I am unsure if I should cap it off or if the dripping will stop over time. It seems that there is some pressure comming from the vent. What should I do??: The seal may be worn. Call back the company that installed the pump...

Q: Electric Hot Water Tank Pressure Release Valve Leaking, Why?: The TP valve is the most crucial piece to your water heater and your safety, If all you do is open and close it in order to stop it from leaking, then you are taking a HUGE chance for it to fail. If that where to happen, you better pray you are not home because the TP valve is the ONLY devise a water heater has to prevent it from exploding. I am not trying to scare you, I just want to make you and anyone else aware of the extreme dangers, besides the temperature and pressure relief valve is very inexpensive and very easy to change.

Q: wife died at 40 still awaiting results of exsaminers report. Can CPR be given to some one with two artificial heart valves mitral and arotic? She the person administering CPR be aware that they are in the heart...: Yes, and it doesn't matter if there are artificial valves or not. The thing about CPR is that it's only done for someone who is actively trying to die. The alternative to doing CPR is to let someone pass away, which is not usually the best course of action (unless they have a terminal disease and have asked not to be resuscitated.) If you are asking whether the presence of heart valves excuses someone from NOT doing CPR... then no. If you are asking whether heart valves + CPR and a bad outcome is because CPR should not have been done, then no to that too. The right thing to do for someone who is pulseless is to start CPR, call 911 and get more definitive treatment on the way. CPR is not going to revive someone - it is only a bridge until a defibrillator and/or cardiac drugs are available. I'm sorry that you lost your wife at such a young age, and I hope you find the answers you are looking for.

Q: I own a 2wheel drive 2003 Hyundai Santa Fe 4cly. The engine light was on the code P0401 came up which is the EGR valve. I had it changed out the engine light came back on after I had made it almost home. I took it to auto zone same code came up that made me take to the shop for repair in the 1st place. Ugh. Please help! What's the problem???: My vehicle is throwing a P0401 code. I was going to replace it, but instead I am going to clean it and replace it. I know the mechanic will want to replace it and charge me well over $100 (I'm seeing the part go for around $52-$55). THe car was recently serviced with the valve cover gasket replaced.

Q: We have a main gas valve outside and there's a gas valve by out air condition and we want to know which way if off and on .. Does anybody know !!!: Generally speaking the valve has a handle that pivots from parallel, to perpendicular. Open is in line, or parallel. Closed is perpendicular. If it's a rotating handle, then the valve stem will be all the way in when closed, or all the way out when open. The valve stem is located in the center of the wheel that you would turn. Hope that works for you.

Q: When I put my check valve on my air line the air doesn't come through the air stone but when I take off the check valve it works. Also I switched the sides of the check valve and it didn't work. Click the link this is the air pump.: Or if you can, go to petsmart and get one there. Petco tends to sell sub-par items and livestock. If you have a tank that is bigger than your air pump was intended, then you will have problems. Say you bought a 10 gallon air pump for your 20 gallon tank. The strength of the pump is only able to push air down to counteract the average depth of a 10 gallon tank, against the pressure of only that much water. However if it were in a 20 gallon, it may not be able to counteract the water and the check valve (which shouldn't be causing much of a problem anyways). Make your line shorter and see if that helps. You don't need tons of extra airline tubing coiled around. Cut it down to the length you need, and try again. Remember, check valve should be OUTSIDE of the water, in the direction indicated on the valve (as to which side is in, which side is out), and it should be closer towards the pump itself. The check valve just prevents any water from dripping back into the pump.
