Normally closed high pressure brass solenoid valve, primarily designed for air and steam, but can be used with other fluids compatible with the materials of construction. Media viscosity must not exceed 25cSt (mm ²/s).
Pressure range: 0-40 bar
Supplied without coil: requires Type 2 Coil
The series 219 solenoid valve manufactured in Italy by ACL srl, are a family of 2-way normally open high-pressure air solenoid valves employing a servo-assisted piston.
The body and cover of the 219 are manufactured in brass, however the following parts: armature(plunger) and springs 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 and/or a stainless steel armature tube. These valves are also available with UL rated coils by special order.
Key features of the 219 series is the minimum differential pressure of 1 bar and the maximum allowable pressure of 40 bar. The 219 is primarily designed for air and steam, but can be used with other fluids compatible with the materials of construction and whose viscosity does not exceed 25cSt (mm ²/s).
The 219 can be fitted with ACL's Type 2 coils, (class F insulation the maximum ambient temperature is +55°C). It is recommended that the 219 series be mounted with the armature tube vertical (solenoid coil above the valve).
