As the accelerator is depressed with load on the engine: such as being in gear, engine speed will begin to increase. As the engine begins to require more air and fuel, the secondary air valve will begin to open. These valves are controlled by a choke pulloff vacuum canister which releases as vacuum in the intake drops. Then the suction of the engine will allow your air valves to open also causing fuel to be sucked into the engine through the secondaries. When these valves open, a cam that they are mounted to will lift the secondary metering rods higher out of the jets which allows fuel to pass more readily through the carburetor and into your engine. Cool sound!

What is the definition of pneumatic valve?
A valve which requires pressurised air to operate (open or close) is known as pneumatic valve. A valve has a valve base through which the media (could be be air, liquid, steam, gas...) flows and a actuator mounted on the base which helps operate the valve. This actuator could be of pneumatic type. (or elctrically operated motorised type)
What is the air pressure valve in the boiler heating system?
I am guessing you are talking about the air charging valve on the expansion tank. That is to charge air to the top side on the bladder which acts as a cushion and compresses to allow the water to expand due to being heated, preventing the relief valve reaching it`s setpoint and lifting.

The back of my Rochester quadrajet carburetor the 4 barrels dont open when at full throttle what could be the issue its a 1984 rochester on a olds 307.?
Quadrajets have a maximum airflow of from 750-800 cfm. Because the secondary side of the carb opens according to the airflow requirements of the engine, the same carburetor size can be used on a large range of engine sizes. The basic 750 cfm quadrajet casting is used from 231 CID to over 400 CID - the big secondary air valves open only as the engine breathes. For example, on a mild 350 Chevy the air valve will never open all the way - because the motor can't use more than 600 cfm or so. Your 307 will simply not require the full use of the secondary air valves, at no cost of engine power however. -DB, 1969 Hugger Orange Camaro
