An air pump check valve comes in a variety of sizes. This type of valve can be purchased for about 12 dollars to about 40 dollars depending on the size required.
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)
An air valve is a spring loaded plastic valve for ventilation. A gate valve is an old fashioned type of water valve where turning a handle lowers a blocking gate over the water inlet. Any sensible plumber now uses ball valves instead.

An air to open valve is a type of control valve that requires air pressure to be applied in order to open the valve. When the air pressure is removed, the valve will close automatically. This design is commonly used for safety-critical applications where a fail-safe operation is needed.
