Pneumatic controls

Hi Everybody,
I posted recently about this. There is a confusing controls issue I know of, and I can't understand it. It involves a quincy air compressor, three Hurst LPW boilers, and many pneumatic actuators and thermostats. Many rooms in the building have no pneumatic pressure, and It's now at the point where the discussion must be made whether to replace everything with electric valves, or keep it pneumatic. Any advice from anyone?


Re: Pneumatic controls

pneumatic controls are actually quits simple once you know the basics behind them. actuators are typically open with no pressure and closed under pressure. look for a valve turned off or another compressor if you have areas with no pressure

Re: Pneumatic controls

We have counted a strange ratio where there are roughly 10 more thermostats than actuators. There is one air compressor that knocks, and has one burnt motor. The diaphragms in the actuators seem to work. The question is: Should the building be converted to solenoid valves or kept pneumatic?
