API 6A GATE VALVES

Vertical Lift Check Valve

vertical lift


A rare feature where instead of a lift hill, a coaster car/train is lifted vertically upwards on a section of track that acts as a lift. When this section is aligned with the rest of the circuit at the top, the car/train moves forwards to complete the ride.


A type of lift where the train rolls onto a section of track and is raised straight up.


Refers to a hardware design that causes doors to open vertically where no horizontal tracks are required

check valve


A valve that closes to prevent backward flow of liquid


A valve which will allow water to pass in one direction but will close and prevent flow (backflow) in the opposite direction.


A check valve, clack valve, non-return valve or one-way valve is a mechanical device, a valve, which normally allows fluid (liquid or gas) to flow through it in only one direction.


Limits the flow of gas to one direction only. Use a check valve between the bubbler and generator to prevent unwanted pressure build up in the generator, and a safety against a low level bubbler. A check valve, such as used on torches, is recommended.
