• 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.
