    Important Personnel Safety and Product Protection Information Throughout this manual, information that is of particular importance to the installation, the safety of operating personnel and the protection of equipment are highlighted by the following three symbols. The WARNING symbol is also used on the equipment wherever necessary.

    Thank you for purchasing a new Intellisys TBV- and TBV-IQ- series throttling butterfly valve or UVD-series universal valve driver from Nor-Cal Products. Before installing and operating the product, please read this manual thoroughly as it contains critical hook-up and operating tips.

    Nor-Cal Products TBV-series butterfly valves and UVDs are designed for downstream pressure control over a wide range of vacuum control applications in conjunction with an APC-series buried box or IQ-series on-valve controller module. The TBV or UVD cannot be operated by other manufacturers valve controllers. All interface and communications connections are made directly to the controller module that, in turn, provides power and position signals to the valve motor. Used with a controller module and the inputs from one or two pressure gauges the TBV-series butterfly valve forms an integral part of a complete downstream pressure control system.
