3321 Electromotive Process Valve
Brand: Burkert Fluid Control Systems
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 with ball screw positions moves the swivel plate at a particularly high rate of 6 mm/s to its desired end position. Thereby it reacts 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 actuator and shut-off globe valve are adapted perfectly to each other with closed design and robust surface. This ensures the hygienic requirements of a fast and residue-free cleaning.
Harsh environments are no problem for the Type 3321 because of the protection class IP65 / IP67 and its high impact and vibration resistance.
Unrivalled cycle life and sealing integrity is guaranteed by the proven self adjusting spindle packing with exchangeable V-seals.
The fieldbus suitable for Type 3321 provides many helpful functions for process monitoring, valve diagnostics and predictive maintenance and thus offers the decisive advantage of a modern process automation.
