Flow Control vs. Bottomless Portalter
Pressure Release Valve
Each NEO Flex comes with a Pressure Release Valve in the underside of the Piston. As a fail-safe, this
Pressure Release Valve has been incorporated to avoid damaging the piston of the NEO Flex and
causing undesired stress on the frame. If the silver foil is ruptured, the valve will bleed pressure up and
through the piston. If this occurs, the valve should be replaced, as below*.

Bottomless 2-in-1 Portalter (Black)
Requires a Quality Burr Grinder!
You will need to “dial-in,” meaning trialing dierent
sized grounds until you get the right pressure. Grind
too ne, and you won’t be able to lower the lever.
Grind too coarse, and the lever will lower without any
resistance and not make espresso.
All Brewers Should Start Here!
The Flow-Control Portalter features a restricted exit
port, which builds pressure for brewing espresso in
the chamber. This portalter can be used with almost
any grinder, or with pre-ground coee, without the
need to “dial-in” your shot. Use for convenience.

*Remove the broken valve by pulling it out by the small recess
at the edge of the valve. Replace by pushing new valve into the
recess on underside of piston, with the foil facing out.
