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.
nothing, its just terminology why A pressure relief valve is a safety device to prevent over pressure in such things as compressor receivers. A pressure reducing valve drops the pressure to the requirements of the user or tool. Such as a demand valve on scuba gear.
They serve two different purposes. An air bleed valve is used to remove air from the circulation system. A pressure relief valve is designed to automatically open when certain pressure levels are reached.
the pressure relief valve start to open at a set pressure and que flow capacity and lift increase as increase the pressure in the system, usually the overpressure rise a 10% above the set pressure. In a Surge relief valve the valve open 100% when the system rise the set pressure and the accumulation on the system it is less than 2%, ussually that valves do not change the fluid direction to handle height flow capacity. That valves prevent a liquid hammer, the standard PSV did not.
A thermal relief valve is a liquid-only relief due to expansion of a liquid with increased temperature.A safety valve relieves pressure due to a gas.It should be noted that "safety valve" is a general term which could refer to Pressure Relief Valves (PRVs) or Pressure Safety Valves (PSVs), terms which are used synonymously in some industries (such as the petroleum industry) to refer to all relief devices in general.

Control valve: Used to modify flow rate in a process control system.It has characterization: linear,equal percentage and quick opening Pressure inlet must be higher than the output pressure Regulator:Diapghram operating valve which controls outlet pressure (reducing application),control inlet pressure (back pressure) or either (differential reducing and differential relief applications
what is differenc between high relief and normal relief
The difference between high relief and low relief is that high relief has more depth and low relief is more casual and not as 3D. In high relief, it's much closer to 3D.
They serve two different purposes. An air bleed valve is used to remove air from the circulation system. A pressure relief valve is designed to automatically open when certain pressure levels are reached.
The set pressure is the pressure at which a relief valve starts to open. When the valve is open and relieving, the pressure will be higher or lower than the set pressure, depending on the system and the valve design. That is the blow-off pressure.
what is that...
relief
A pressure relief valve is a safety device that releases excess pressure from a system to prevent damage or failure. It helps maintain safety by ensuring that pressure does not exceed safe limits, reducing the risk of explosions or other hazards.
The term that describes the difference in elevation between the highest and lowest parts of an area is "relief."
relief
ER is extended relief and XL is immediate relief
