Product Description
Reliability: long service life of 30 million cycles
Choice of internal/external supply with selector seals (vacuum use to –0,950 bar)
Modular assembly with joinable subbases
Subbases with side or bottom ports
MULTIFUNCTION
Multifunction valves are equipped with 2 pilot selector seals on
the top face on both the pilot and the return sides. Each selector
seal can be set on 2 positions, allowing internal or external
supply to the pilot or return operators in both the air and
solenoid air operated versions. External supply allows the valves
to operate with a supply pressure ranging from 0 to 12 bar and
under vacuum pressure.
Each seal includes a tag with an arrow to be set into the notch
corresponding to the required pilot function (see below).
Modifi cations of the function are very simple. The valves are
delivered pre-set according to the valve code selected on your
order.
USE WITH NON-LUBRICATED AIR
The ISO-compliant valves will operate satisfactorily with
lubricated, non-lubricated or dry air due to their patented,
T-shaped oscillating sealing element backed with a cushioning seal.
This sealing assembly maintains a minimum pilot pressure which
remains constant even if the valve is switched off for a longer
period of time. On restart, the valve’s performance will be the
same as under continuous operating conditions.
This characteristic ensures safer operation both on valve start-up and during operation.
MANUAL TESTERS INDICATING THE POSITION OF THE SPOOL (OPTION)
On request, the spool valves can be delivered with manual testers
to check the position of the spool or move it by manual override.
