Direct acting solenoid valves Series A

2/2-way – Normally Closed (NC) and Normally Open (NO)
3/2-way – Normally Closed (NC) and Normally Open (NO)
Series A solenoid valves are of the directly operated type and can be used with dry or lubricated air.
They are available in the 2/2 and 3/2-way versions with normally closed (NC) or normally open (NO) operation.
As shown in the following tables, they are supplied in different versions according to the type of body, threaded ports and orifice.
They can thus satisfy various operating and installation requirements.The solenoid can be easily and quickly replaced without interfering with the pressurised part of the valve.
On the same mechanical part different types of solenoids can be interchanged.
The choice of solenoids determines the performance of the solenoid valve in terms of consumption and pressure.
