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.
Double Regulating Valve normally have five functions. 1.Presetting 2.Measuring 3.Isolating 4.Filling 5.Draining
pressure relief valve relief the excess pressure which is developed in the syatem, while pressure reducing valve reduces the pressure and supply it to the system.
The purpose of both the valves is same - that to maintain a certain level(in a vessel or tank...) Simple Level valve could be referred to an ON - OFF valve where as control valve could be referred to an analog type of valve. On - OFF valve is for a crude control of level, while control valve is used where a fine level control is needed.
it controls the pressure

Did you mean PCV [positive crankcase ventilation]....that valve helps keep engine gasses from going to the atmosphere but wont allow intake pressure back to the crankcase.
To regulate the pressure to a pre-determined amount.
On a 1991 Mustang 5.0, the Positive Crankcase Ventilation (PCV) valve is typically a small, cylindrical component made of metal or plastic. It is located on the driver's side valve cover and connects to the intake manifold with a hose. The valve often has a rubber grommet that helps secure it in place and prevent oil leakage. The PCV valve plays a crucial role in regulating crankcase pressure and reducing emissions.
Positive crankcase ventilation. Uses suction and a one way valve to remove pressure and vapors from the engine.
Chech the pcv valve. The oil is due to excess crankcase pressure.
A water pressure valve replacement is necessary when the valve is malfunctioning or not regulating water pressure properly, which can lead to issues such as low water pressure or damage to plumbing fixtures.
The "Positive Crankcase Ventilation" valve pulls fumes from the inside of the crankcase, back into the intake. The general idea is, don't allow the crankcase to build pressure, since that's what contributes to main seal failure and severe oil leaks.
A PCV valve is for positive crankcase ventilation. It is to keep crankcase pressure from building up in the engine. If it does it can cause seal leakage, air filter contamination and engine blowby.
Your positive crankcase ventilation valve, or PCV, is probably stuck closed. The PCV vents crankcase pressure from the engine into the intake. When this valve sticks closed the pressure has to escape somewhere and it normally will escape through the dipstick tube.
One possible cause is a blocked PCV (positive crankcase ventilation) valve. As your motor is running the crankcase will build with pressure and the PCV system will let the motor breathe. If the PCV valve is blocked or faulty then the motor will look to release the pressure somewhere else.
