npt, national pipe thread, is a standard for threads on a screw. I (not a plumber) don't believe "npt valve" makes sense , but probably refers to a valve which has npt threading.
Yes, a NPT Valve would be a valve with pipe threads as opposed to a sweat valve which has solder connections. There are several other type of piping connections too.

What is pressure valve?
There are various kinds of pressure valves. Perhaps the 2 most common in homes are the PRV (pressure regulating valve) which is on most incoming water pipes from a city supply. This valve limits the pressure entering the home system, bringing it down from city mains pressure. The second is on every hot water tank, and this is a relief valve, which will open up if the pressure in the tank becomes too high and vent the excess water down the drain.
How do you drain water tank to build pressure?
To drain a water tank to build pressure, first, turn off the power supply to the tank and close the inlet valve to prevent further water flow. Next, open the drain valve at the bottom of the tank to release the water, allowing it to empty partially or completely, depending on your needs. Once the desired level is reached, close the drain valve and reopen the inlet valve to refill the tank, which will help build pressure as the water heats up. Finally, restore power to the tank.
Is it normal for water to leak out of the pressure relief valve on a hot water tank?
YES, as a hot water tank should NOT have a relief valve it should have a combination of Temperature and Pressure relief valve. Normally a T&P is SET @150 PSI and Or 210 Deg F. If the valve leaks this is a sign of an impending disaster such as a pressure vessel exploding. A professional will check to make sure (NBBI, ASME, LMP,) 1- The pressure is not exceeding the high limits of the system 2- Make sure the aqua stat is actually functioning 3- The pressure temperature relationship of the system is not exceeded
Where is the inlet and outlet of your pressure tank?
A pressure tank for a pump & well potable water system only has one connection. To connect the pump and tank to your house's water inlet, simply connect the tank and pump together with pressure rated pipe, SCH 40 PVC works fine. In that line, cut in a TEE fitting, and from that T, connect the house inlet with a valve to shut the water off.
What does water pressure mean?
Water pressure refers to the pressure of water in a system. In a home it will be 30-50 psi typically and this is governed by the municipal pressure or by a well tank.
What is the purpose of the expansion tank valve in a heating system?
The expansion tank valve in a heating system is used to regulate the pressure within the system by allowing excess water to flow into the expansion tank when needed. This helps prevent damage to the system from excessive pressure buildup.
What is the purpose of a TP valve and how does it function in a water heater system?
The purpose of a TP valve in a water heater system is to release excess pressure and temperature to prevent the tank from exploding. It functions by opening when the pressure or temperature inside the tank exceeds safe levels, allowing the excess water to escape and relieve the pressure.
What are the benefits of using a float ball valve in a water tank system?
A float ball valve in a water tank system helps regulate water levels, prevents overflow, and ensures consistent water supply. It also helps maintain water pressure and can save water by stopping the flow when the tank is full.
How do you install a check valve between water pressure tank and water pressure pump?
since check valve holds water in the line can a hand pump be installed between the check valve and water tank?
What is the relationship between the water pressure, tank air pressure, and the overall performance of a water pressure tank system?
The water pressure in a tank system is directly related to the tank air pressure. The tank air pressure helps regulate the water pressure and overall performance of the system. If the tank air pressure is too low, the water pressure may drop, affecting the system's efficiency. Conversely, if the tank air pressure is too high, it can cause the water pressure to be too high, potentially damaging the system. Maintaining the correct balance between water pressure and tank air pressure is crucial for optimal performance of the water pressure tank system.
Can you shut off the inflow valve to hot water heater for a day without harming system if so should pressure valve be left open and limited usage of hot water?
If you have a leak on the hot water somewhere in the house and the water input into the tank is not running, the tank will lose it's water. And if it is an electric tank, the elements will burn out. Gas hot water tank should be no problem. Pressure valve does not have to be open.
What location in a well water system should the check valve be placed?
In the incoming water line from well, before pressure tank.
What is the purpose of the well tank pressure relief valve and how does it function to maintain the optimal pressure in the system?
The purpose of the well tank pressure relief valve is to prevent the tank from becoming overpressurized, which can lead to damage or safety hazards. The valve functions by releasing excess pressure from the tank when it reaches a certain level, ensuring that the pressure in the system remains at an optimal and safe level.

How do you know the bladder in a hot water heating system is good?
If the bladder is bad in your expansion tank the tank will fill with water. When this happens the pressure in your furnace will exceed 30lbs and your pressure relief valve will blow off.
What are the basic components of residential water well system?
Well, pump, storage tank, pressure switch, pressure gauge, Cycle Stop Valve, tank tee, drop pipe, wire, (with a submersible pump) gate valve and possibly water filtration. bob...
Is it necessary to have both an expansion tank and a pressure relief valve on a hot water heater?
You must have a pressure relief valve. I believe it is code nationally. I don't think you can buy a hot water tank w/o one. Expansion tank needed also if water meter has backflow preventer, check with local water authority if it does.
