Product Description

Electromotive 2/2 way globe valve (on/off)

The innovative Buerkert 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 degree of protection 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 fieldbus-compatible Type 3321 shut-off valve offers, which is compatible 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.
