Does the air need to be failed to start handjacking?

No it does not. You can hand jack at anytime

at 2:07 I'm pretty sure yall have that visual backwards. The old control disk is thinner, and looks like it's on the right side and seeing the actual turbulent flow(being directed down) would indicate it's backwards.

If the orifice is oversized, what kind of problems would I see?

Question: How come for a 627 regulator (and others) if we reach the maximum inlet pressure than the trim size regulator can handle, how come the flow capacity at the max inlet pressure is way less than the flow capacity with an inlet pressure that's half the max inlet pressure? Example: Table 9 - Type 627 Capacities for NPS 2 body size and orifice size = 1/2 in - Outlet Press = 60 PSIG; Inlet pressure: 300 PSIG => Capacity = 79,000 SCFM. For the same regulator, same outlet pressure, if inlet pressure = 750 PSIG => Capacity = 32,000 SCFM. Thanks for your help!

The orifice will dictate that if the max pressure is not adequate. Instead of maxing out spring, you could up the orifice

Or maybe just the capacity of the reg can’t handle that increased inlet pressure. Maybe everything just needs to be increased. Reg head, diaphragm etc

Oh my god, amazing break down on how a pressure regulator works. My instructor was using a black an white 2d photocopy of a regulator to explain how a regulator works. Thank you for the video!

Just a quick question: gas supply is on, but nothing is coming out for the pilot light. Any ideas why?

Pilot light ? Your referring to a pilot on an appliance ?

Hello, at 2.06 you mention injecting other power. Can these terminals be used to supply +24VDC to a field device, for example, a flow switch that requires power, or do I require a +24VDC power output charm ? thanks.

What is the regulator book sitting on the table out of curiosity?

When the diaphragm fails (note I said "when" not "if") this regulator will fail open. Surely that can't be how real regulators fail. What am I missing?

The regulator will fail open and will relieve out of the atmospheric vent/ relief vent

Hi Control Team, do you know how the vent chamber works? and how the vent pressure chamber can be calculated?
@mehranghodosi39926 жыл бұрын
When the pressure is very high....the vent works...and gas realise in air....and pressure below difragm is low
@pq92546 ай бұрын
The vent has a set pressure based on the spring. If the reg started to fail, allowing higher pressure in, if the pressure reaches a certain level, the vent spring will give and high pressure will vent out keeping the inside of the building safe

nice video. It seems like the downstream pressure is a function of atmospheric pressure and upstream pressure? if a high pressure weather system comes in wouldn't that result in too much downstream pressure? A spike in upstream pressure will have a similar effect right?
@mehranghodosi39926 жыл бұрын
I think in different (high pressure from sea)weather regulator works in low pressure
@mehranghodosi39926 жыл бұрын
Because regulator works in atmosphere pressure
@Camlo893 жыл бұрын
That’s where an internal relief valve comes in handy it reliefs that spike in pressure just in case to protect downstream pressure
