Boiler Safety Valve Pressure


Safety Valves in Boiler System - Bright Hub EngineeringSafety valve is used to guard the boiler against the excessive high pressure of steam inside the drum. If the pressure of steam in the boiler drum exceeds the working pressure then the safety valve allows blow-off the excess quantity of steam to atmosphere. Thus the pressure of steam in the drum falls.How To Identify A Faulty Boiler Relief Valve30/6/2014 · I know it's fairly low pressure but using a "safety valve" to restrict operating pressure doesn't sounds like a good idea to me. However setting any operational limit is up to you - it should not affect any ratings of the vessel and you could have any pressure you like equal to or less than the MAOP which itself can be set anywhere equal to or less than the design pressure.
