2/2-way Solenoid Valve in three versions

6240 G 1/4”, G 3/8”, G 1/2”

• High performance – small size
• High pressure version up to 40 bar
• High temperature version up to 180 °C
• Fast-acting
• ATEX version optional
2 (A)
• Without differential pressure switching

1 (P)

Type 6240 is a pilot-controlled solenoid valve with servo-piston and Envelope Dimensions [mm] (see datasheet for details)
forced valve lifting. The valve opens without differential pressure from
zero bar. The special construction makes it possible to use it with dry
gaseous mediums with high pressure and steam up to 180 °C.
