A properly designed steam system is extremely important. Clean, dry steam through your steam distribution network maximizes the quality of steam, and protects all related components thus keeping costs and maintenance to a minimum.
Principles of Operation of the Pressure Reducing Valve: – Normal positions before start-up are with the main valve closed and the pilot valve held open by spring force or air pressure. Entering steam passes through the pilot valve into the main diaphragm chamber and also out through the control orifice. As flow through the pilot valve exceeds flow through the orifice, control pressure increases in the diaphragm chamber and opens the main valve. As steam flows through the main valve, the increase in downstream pressure feeds back through the pressure sensing line to the underside of the pressure diaphragm. When the force below that diaphragm balances the compression force of the spring above it, the pilot valve throttles. The control pressure maintained in the main diaphragm chamber positions the main valve to deliver just enough steam for the desired delivery pressure. Adjustment of the spring or air pressure above the pressure diaphragm changes the downstream pressure set point. When steam is no longer required, the sensing line pressure increases closing the pressure pilot and the control pressure bleeds back through the control orifice. This allows the main valve to hold the desired reduced pressure, and it may close tight for a dead-end shutoff.

I’m not a professional, Do not assume this is a perfect installation. If you believe only lamborginis should have lambo doors, well NO ONE asked you to watch the video. I got the hinges from www.extremelambodoors.com, Here is another link that I used as a reference when installing my hinges,

I was forced to use a grinder, Do NOT forget to paint the grinds if you preformed this, as they will also rust.
I will do my best to respond as effectively to any question. But this is a video just to prove you DONT need a professional to install everything. You just need to actually get up and do it yourself.
Its not rocket science and well not everyone is the brightest peanut in the Turd, But its completely possible for someone to figure this out.
Best of Luck.
