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.
