Burkert Type 6240 Servo-assisted 2/2 Way Piston Valve

  

 

 

 

The 6240 valve is a servo-assisted piston valve. The stopper and plunger guiding tube are welded together to enhance pressure resistance and leak-tightness. Various seal material combinations are available depending on the application. The housing design and surface quality enable maximum flow rates. The coils are moulded with chemically resistant epoxy. An optional sliding ring bearings increases the life cycle with dry gases. In combination with a plug in accordance with DIN EN 175301-803 Form A, the valves satisfy protection class IP65. Stainless steel valves satisfy NEMA 4X. This product can be combined with Cable Plug Type 2518 and Cable Plug Type 2513.

Features

• Servo-assisted and compact piston valve with diameter of up to DN 13
• Vibration-resistant , screwed coil system
• Increased leak-tightness with welded plunger guiding tube
• Safe opening with hard-coupled piston system
• Explosion proof versions
