FIRST TIME HERE AM LOOKING FOR A MANUAL FOR AN OLD ...

Jan 21 2016 · I acquired a 394M Mirro Matic pressure cooker and found the "jiggler" to be unreliable so I removed it and put a pressure gauge on it that reads to 20 pounds. I usually cook to 5 to 10 pounds pressure. This old cooker works really well and I have to watch it. It doesn't have any safety devices.

What Should The Boiler Pressure Be When The Heating Is On?

Boilers are built to quickly control these jumps in pressure via the pressure relief valve. This means that you can safely use your central heating and run hot water at the same time. Your boiler pressure should not increase by more than 1 bar above its optimal working pressure when you turn the heating on.

My hot water boiler keeps increasing pressure when it runs.

Nov 17 2008 · My hotwater boiler keeps increasing pressure when it runs. Normal pressure is 12psi but it has risen to as high as 40psi though the max pressure is indicated as 30psi on the gauge. I rcently replaced the flow control value which I set to the normal 12psi prior to use of the heater. The house is dual zoned and the problem occurs in bith zones.

Boiler Pressure Too High Low Keeps Rising Dropping ...

The ideal boiler pressure should be between 1 to 1.5 bars on your pressure gauge when your heating is switched off. Around 2 bars is a normal pressure level when your boiler is active/heating up. Anything below 0.5 is too low and must be replaced.

Safety-Relief Valve FAQ

A: Back pressure reduces set pressure on a one-to-one basis i.e. a valve set at 100 psig subjected to a backpressure at the outlet of 10 psig will not actuate until system pressure reaches 110 psig. Back pressure drastically reduces capacity; typically backpressure of 10% of set pressure

Safety Valve Selection | Spirax Sarco

By adding the 0.1 bar shut-off margin the safety valve set pressure has to be 10% greater than 6.4 bar. For this example this means that the safety valves set pressure has to be: The set pressure would therefore be chosen as 7.11 bar provided that this does not exceed the MAWP of the protected system.
