Codes vary, check max. press. allowed in home, if press. higher than allowed by code coming into home, than install pressure red. 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.

There are no pressure valves on a regular home hot water system. If you are meaning some kind of industrial application,then say what exactly it is.
This depends upon how high the temperature is increased. To make food cook quicker, when water is placed in a pressure cooker it is allowed to heat up to a much higher temperature than its normal boiling point of 212 degrees Fahrenheit at sea-level. But, at a certain preset pressure, the pressure relief valve will open and release steam. Without this valve the cooker would explode. The same is true for a water heater in your home.
Reverse airflow feels a chamber inside the gauge and reads the pressure equal to the inside of the tyre its that simple. Same for air compressure, when the pressure is applied it seals the valve on the gauge end then back pressure fills the chamber inside the gauge when you release the gauge from the tyre valve the pressure has gone!!
The residential house Pressure Reducing Valve (PRV) usually has setting capabilities of between 25-75 PSI. Normally, 50 PSI is suitable.

It is pumped into your home water system by the city water supply, or if you have a well, it's pumped into a pressure tank and then into your home. Either way when you open a faucet (essentially a valve) the water will come out.
The proper fuel pressure of a 1995 Astro van should be between 55-61 psi. Checking the fuel pressure at home requires a fuel pressure gauge and knowledge of the location of the shader valve on the fuel rail.
There are pressure boosting pump systems available. Do you have a pressure reducing valve installed that may be faulty? You should consult a licensed plumber on this.
