Burkert_Type-8681The Burkert Type 8681 control head from Charlotte, N.C.-based Burkert Fluid Control Systems is optimized for the automation of pneumatic hygienic process valves. The Type 8681 performs all pneumatic actuation, feedback and diagnostic functions, as well as bus communication. It is universally adaptable and combines with all commercially available valve types that use a rising stem upper actuator configuration.

As the control head — made from chemical-resistant materials — is durable, easy to clean, features IP 65/67 protection and has a positive pressure electronic housing, it is ideal for use in severe wash down applications.

Depending on the process valve involved, as many as three pneumatically actuated seat movements can be controlled independently.

Burkert says the Type 8681 should be recognized “because it is the only bridge in the industry, thus far, of standardizing within the control tops of the sanitary single seat and mix-proof valving. This control top can universally adapt to all major sanitary valve manufacturers products… It is a stalwart performer in the wash down environment as it keeps the humidity out of the control head through positive pressure and allows maintenance on the valves to be very easy via a manual override without opening the valve top. This crucial step allows the plant staff to focus solely on removing the valve insert and repairing the damaged seals without worrying about shorting any control tops.”
