Introducing ICO4-PST
The First Smart Solenoid Valve with
Fully Integrated Partial Stroke Testing
The ICO4-PST is the first fully integrated partial stroke testing
solution with the control system built into the market leading
Maxseal ICO4 high integrity solenoid valve. With the lowest safe and
dangerous failure rates of any intelligent PST system on the market
and always providing the highest possible Diagnostic Coverage, the
best possible SIL performance is guaranteed.
» No dedicated PST device required therefore significantly reduces
engineering requirements
» High level diagnostics with position, pressure and time monitoring
» Simple Pass/Fail reporting
» Dual override mechanism eliminates possibility of over-stroke
» Compatible with valve speeds from 2 to 120 seconds
» SIL 3 certified as 1oo1
» -40°C … +60°C
» Local testing using HART 475 communicator, remote testing via HART
Working closely with customers in the
global oil and gas industry, we see the
need for a no compromise solution for
partial stroke testing. It is clear that the
best way to eliminate the compromises
of positioner systems is to use the control
mechanism of the electronic solution;
whilst the best way to eliminate the
compromises of the electronic solution is
to employ the packaging of the positioner
system. Now add to this the benefits of
using a high integrity solenoid valve and
we are left with a clear path – namely, the
integration of the PST control electronics
into the termination housing of a high
integrity solenoid valve.
