The innovative Bürkert process on/off valve Type 3321 is the solution when it
comes to shut-off tasks under demanding operating conditions. The electromotive
actuator of the globe valve with ball screw moves the swivel plate to
the desired end position at a particularly high speed up to 6 mm/s. Thereby
it reacts almost instantaneously to process signals. If necessary, the safety
position can be approached by an optional energy storage in case of power
failure. The electromotive actuator and shut-off valve are adapted perfectly to
each other with closed design and robust surface. This ensures the hygienic
requirements of fast and residue-free cleaning. Harsh ambient conditions are
no problem for the electromotive globe valve type 3321 due to the protection
class IP65/IP67 and the high impact and vibration resistance. Thanks to the
tried-and-tested, self-adjusting packing gland with exchangeable V-seals,
the globe valve achieves maximum service life and tightness. The Type 3321
shut-off valve, which is suitable for fieldbuses, offers the operator many
helpful functions for process monitoring, valve diagnostics and preventive
maintenance and thus the decisive advantage of modern process automation.
