Burkert Fluid Control Systems'
new Type 8681 process valve control heads are designed to assemble with all commercially available hygienic ball valves and butterfly valves, as well as single-seat, double-seat, and mix-proof valve configurations.
The control heads are designed for use in hygienic processes in the dairy, food/beverage, biotechnology and pharmaceutical industries. They have a smooth and chemically resistant IP65/67 enclosure that is easily cleaned and suited to use in wash-down areas.
Internal design elements include a contactless internal positioning system which negates internal wear, and manual overrides on the pneumatic pilots. Green, amber and red LEDs indicate the valve switching position, or maintenance/fault requirement, with status/colour settings customised via DIP switch.
The control heads are capable of controlling strokes up to 85mm with three-positions, with 200 l/min pneumatic air for each pilot valve, and are certified for explosive environments, with ATEX Cat. 3, Zone 2/22.
