The Type 2031 Diaphragm Valve when coupled with the Type 8630 TOP Control System serves as a flow or pressure control valve system. The valve can handle viscous and aggressive fluids up to 284ºF. The TOP Control positioning unit, a complete electro-pneumatic valve actuation system offering on/off and continuous functionality, features a directly connected PID-Controlled feedback loop internal with the actuator. Valves are also available in PVC, CPVC, PVDF, and Polypropylene.
Burkert Type 8630 TOP ControlNow with PID Process Tune
The Award winning Burkert TOP Control is well regarded for being able to accurately control process systems using Diaphragm and Globe control valves. Burkert has now added a self-tuning PID Process Tune function. Proportional (P), integral (I) and derivative (D) control is an advanced continuous control methodology used in control loops. Stand alone PID control loops have been integral to several Burkert products for many years allowing decentralized control thus reducing total control system costs to the user. Proper PID tuning ensures rapid response with little or no overshoot, providing excellent and reliable control for most process control applications.
The addition of the auto PID Process Tune capability to the TOP Control will control the system for a short time to determine the most appropriate values for the PID control values. The proper setting of these values is typically done with trial-and-error that is time consuming and normally requires special training. Now with the touch of a button, this software allows the system tuning to be quick and optimized. This tuning accounts for any non-linearity caused by the stroke time of the valve. This software enhancement further reduces the Total Cost of Ownership- with even less commissioning and enhanced valve performance.
