Secure operational pressure with IL220 lock-up valve
As an industry rule and to ensure efficiencies, downtime on all pro-
duction lines should be kept a complete minimum. Brian Abbott,
Product Manager at SMC Pneumatics elaborates, saying: “SMC
supports our customers in this regard by constantly developing
products that help contribute towards avoiding downtime, as well
as ensuring the critical safe integrity of a system.”
Adding to its offering is SMC’s IL220 lock-up valve of the IL200
series. “This valve helps to maintain the operational pressure, even
when supply pressure is lost by switching to a second supply of
pressure as a 3/2 way valve”.
The maintenance of the operational pressure and/or switching
to a second pressure supply ensures the shift position of the valve
further down the production line. “The advantage here is that the
system retains a defined valve position should this fault occur,”
says Abbott.
The IL220 lock-up valve has many talents. It is suitable for use
in all industrial applications where the operational pressure has to
be ensured even in the case of a loss of the main pressure supply.
Highly sensitive instrumentation for process control would benefit
where a safe or last position needs to be maintained either via a
secondary supply line or a back-up tank. Here the IL220 does the
switch automatically when the set critical pressure is reached. As it
is completely mechanical even a loss in electrical system monitor-
ing does not affect the safe switching of the valve.
