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.
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.
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.
The relief valve should be at least as large (in BTU/hr capacity) as the input of the boiler. A 3.5 million input boiler would need then a relief valve to handle at a minimum 3.5 million BTU/hr.
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.

Normaly, every centrifugal type comprssors provided with an antisurge valve or surge control valve. when compressor handelled with surge, the proveded surge control valve will become open automatically and the cycle will repeated till the comprssor is in surge.
A diverter valve is used in turbocharged car engines as part of a pressure relief system. It helps to prevent a compressor surge as well as reduce the wear and tear on the engine and turbocharger.
The relief valve is part of the oil pump.
Propane tanks are required to have a safety relief valve. The relief valve is a safety device on the propane tank to vent excess pressure.
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.
A tell tale on a relief valve is a small opening or connection that allows excess fluid to escape when the relief valve opens. It is used to visually indicate when the relief valve is relieving pressure and discharging fluid. Tell tales are important for monitoring the performance and functionality of relief valves in a system.
Relief valve always position in the suction line in oreder to relief the extra pressure, while safety valve is always placed at discharge line to release excess pressure.I would take that one step further by stating that a " RELIEF VALVE" is one that is "meant" to be lifted off its seat, as opposed to a "SAFETY RELIEF VALVE" which is not!DIFFERENCE BETWEEN RELIEF VALVE AND SAFETY VALVE:1. Releif valve is applicable in the fluid system.safety valve is applicable in the gaseous system.2.Relief valve opening is directly proportional to the pressure rise.Safety valve opening is will happen at after reaching the setpressure.3.Mode of relif vlave line is again connected to the suction.But in the safety valve is just vent-out there is no connection tosuction.
Converter relief valve ensures high line pressure does not flood/overrun the solenoid.
The high oil pressure relief valve is located in the oil pump

You need to CHECK the EGR Valve.
