Data Sheet/Certifications:

 

The series 123 solenoid valve manufactured in Italy by ACL srl, are a family of 2-way normally closed high-pressure  solenoid valves employing a servo-assisted piston.

The body and cover of the 123 series valve is manufactured in brass, all other parts: piston, armature(plunger), armature tube and core, springs and top cover bolts are stainless steel. The piston ring is produced from reinforced PTFE, the main (piston) seal is also reinforced PTFE, the pilot seal is FPM.

Optionally, these solenoid valves can have the brass body electroless nickel plating, typically to protect against corrosion.

Key features of the 123 series is the minimum differential pressure of 0.7 bar and the maximum allowable pressure of 200 bar. The 123 is primarily designed for air and water, but can be used with other fluids compatible with the materials of construction and whose viscosity does not exceed 25cSt (mm ²/s).

The 123 can be fitted with ACL's Type 2 and the more powerful Type 5 coils. It is recommended that the 123 series be mounted with the armature tube vertical(solenoid coil above the valve).
