Servo -Assisted Solenoid Valve Switches from Burkert
Burkert’s new type 6240 valve is an extremely compact, servo- assisted solenoid valve for universal use with neutral gases, liquids such as compressed air, water and hydraulic oil, and also steam. Believed to be the only valve of its type on the market, the servo assisted 2/2 offers the major benefits of switching up to 16-bar without differential pressure, plus extremely fast operation (20ms opening), small size and high performance.
The Type 6240 is a NC 2/2 servo- assisted valve designed for use in gas handling applications; in compressors and shut-off valves in gas facilities. In addition, the valves are also ideally suited to steam sterilisation. The Type 6240 valves are well equipped for these tasks: they are manufactured with brass or stainless steel (316L) bodies, internal parts of brass/stainless steel, and PEEK, and FKM seals, with EPDM and PTFE variants upon request.

Supplied with either G 1/4 or G 3/8 ports, the Type 6240 has a 6mm orifice, delivering high flow of 0.6 m cubed/h at pressures up to 16-bar. This standard version is suitable for use in the temperature range -10 deg C to +120 deg C (FKM seals), or -30 deg C to +120 deg C with EPDM seals, which are available upon request. However, for applications requiring temperatures and pressures outside of these ranges, Burkert offers an extended version of the 6240, which operates up to 25-bar and 180 deg C.

The Type 6240 offers the flexibility for dry as well as ‘wet’ operation; and it provides the highest levels of actuation performance and reliability with insulation class H epoxy coils, which have IP65 ingress protection with cable plugs fitted. The coils are rated 24 V DC, which facilitates mobile applications, or 24 V and 230V ac (50Hz), with other voltages upon request.
