New to manifolds and twinsets? FAQ: See how it works

When the manifold centre valve is in the “open” position, both cylinders will be equalised, acting as a larger gas supply whether the diver is breathing off the primary or backup regulator.

So long as left and right-hand valves remain open, each regulator will give access to what is now a single gas supply.

When the manifold valve is in the “closed” position, the cylinders will be isolated from each other and run independently. Effectively creating two separate gas supplies accessed by the backup or primary regulator, respectively.

The main advantage of the twinset manifold is that it provides redundancy in case of failure involving either side. Closing the manifold valve will effectively isolate one cylinder (one side) from the other, providing the diver with the remaining gas from the valve on the functioning side.

If the manifold is in an open position, but either the left or right-hand cylinder valve is closed, the regulator attached to that valve (post) will not provide access to the gas in any of the cylinders.

That post's valve will have shut down gas flow to the regulator attached to it, even if the manifold valve itself is open. However, the regulator on the open post will still have access to the total gas supply (both cylinders) unless the manifold is closed.
