Type 6519 NAMUR
3/2 and 5/2 Way Solenoid valves
with NAMUR lnterface
|
|
|
|
Design and Function
The type 6519 NAMUR is a high quality servoassisted solenoid valve, in
3/2 and 5/2 way with NAMUR interface. Piloted by the Burkert 32 mm
solenoid system for standard version or by the FM approved Class I Div. I
or Class I Div. ll solenoid system for explosion proof version.
The high flow rate valve is light in weight, corrosion resistant and has
a long and reliable service life on lubricated and unlubricated air.
The valve comes with manual override and pressure indicator.
