In my opinion thebuilt in overpressure relief valve is incorporated in the
new poseidon first stage because the Triton second stage only freeflows at
high intermediate pressures (>30bar is the figure I heard). The Jetstrem
(Odin) second stage has a built in relife valve in the hose connector.
The price =A428 seems ok. As far as I know the poseidon add-on relief valve
is only made with the old G1/8 (BSP1/8) thread so you need an adaptor
for most first stages.
