Needle Valve
What do they mean by a 2 way valve when giving TPN to patients?
(How can you use a 2 way valve for that? How is that set up?)
My book says:
"Needless systems included recessed needles, plastic cannulas, and one-way valves; these systems decrease exposure to contacminated needles.
Do not administer TPN or blood products through a one-way valve."
What do they mean by that?
That's all it says. Thanks for the info. though.
I can't imagine why a one-way valve could not be used for TPN or for blood administration, unless for some reason there was concern that the valve might now open at the low flow rates associated with the administration of blood or TPN. I seem to recall in-line filters that also served as one-way valves for TPN, but my memory may be faulty. Can you provide any more of the text from your book?

TS5420 Needle valve use in Humidity Indicator application

This is one of those questions which prompts a request for a wiring diagram so that we can see exactly what you have done.
If the test lamp is operating and you replace it with the valve but the valve does not open, the problem will depend on the type of valve. Is the valve a solenoid valve or a motor driven valve. You have mentioned a limit switch. This makes me suspect that you might have a motor driven valve. If this is the case and the valve's gate is now OPEN, nothing will happen unless you close the valve. If the valve is a solenoid valve, the armature might be jammed in the barrel. To test for this, connect the valve,and tap the valve barrel with a big screwdriver. If the armature is slightly stuck, this tapping might free it. The other problem might be that the operating coil had developed an open circuit. To test for this, disconnect the valve from the 110 V supply and test the resistance of the coil with a multimeter. WARNING: If you are not trained to be messing around with the mains supply, you must be very careful if you are to avoid electric shock or burns. Make sure that you unplug the whole set-up from the wall socket, before touching anything.
ADDITIONAL ANSWER: In light of the additional information that you have provided, I am now able to tell you that valves do have a pressure rating but this is usually the maximum pressure at which the valve will not "leak" when closed. If your valve is a washing machine water valve, it is designed to deliver water at the standard water mains pressure (which is fairly high). Since you are using it to drain a tank with a "low head", the rate of flow will be low compared to what it would be when used in a washing machine. Furthermore, the "seat plunger" might not be rising fully — this would limit the rate of flow.
