Universal, Digital, & Micro Valve Drivers
Valve Driver Overview
Kar-Tech's valve drivers come in three flavors, the Universal Valve Driver, loaded with preset valve information for all the major manufacturers presently on the market, the Digital Valve Driver, custom-tuned for your application, or the Micro Valve Driver - an extremely low-cost two input/two output proportional valve driver for simple applications. All varieties offer advanced setup and calibration via Kar-Tech's patented Palm Pilot interface, and have been designed rugged enough for any application. With Kar-Tech's system, setting up your machine is as easy as defining your inputs and outputs, and defining which ones to talk to each other. Typical setup time is less than five minutes, and the ability to save settings makes attachment setup a breeze.
At A Glance:
- PDA or PC Calibration: Set mins, maxes, ramps, frequencies, and check your results with built-in diagnostic tools.
- Flexible: Available from 1 input, 1 output up to 20+.
- Built To Last: Silicon-coated or epoxy-potted electronics inside an IP-67 enclosure.
- User Programmable: YOU select which inputs mesh with which outputs.
Basic Technical Info:
Kar-Tech's valve drivers operate between a range of 9 to 35VDC, and are protected for voltage spikes and reverse battery connection. The number of I/O are custom-configured for the customer, or in the case of the Micro Valve Driver - two inputs, two outputs. All valve drivers have an operating temperature range of -40 to 85C.

Intellects and Valve Drivers
The Intellect is a programmable fluid control instrument with non-volatile user program memory and system expansion Input/Output (I/O) used for fluid selection and redirection.
The unit includes:
- a valve mechanism driven by a stepper motor and the electronics required to control the motor,
- the user I/O,
- host controller communications. Two way communications are through RS232 or RS485.
Multiple Intellect configurations share standard RS485 communications, with up to 15 units being addressed on a single bus. A single RS232 interface allows communications between a host PC and any of the units on the RS485 bus. This bus is fully compatible with the Kloehn Ltd. V6 Syringe Drive Module, allowing the designer/user to mix pumps and Intellects on the bus, as desired.
The Intellect can also operate in stand-alone mode without the intervention of a separate controller. In this case, programs can be automatically started at power-on, and user-supplied external switches can be used to initiate user programmed sequences. Two front panel push button switches allow for simple manual control of the valve positions. In addition, a front panel indicator lights automatically if an error should occur.

Neles SwitchGuard is one of the latest additions to Neles SmartSolutions product range. It can be used on top of all valve actuators in all industry areas, but its benefits can be best capitalized in high cycling and process critical on/off applications.
Since SwitchGuard is an integrated solution, it reduces installation costs by eliminating the need for external solenoid valves. The high pneumatics capacity of SwitchGuard makes it possible to reach fast valve opening and closing times without any extra instrumentation. This way also the need for engineering work is minimized.

Hydro-Control V- Water Control System for Concrete Mixing
Simple to use, accurate water control unit for use with the Hydro-Mix for manual or automated batch plants
The Hydro-Control V is a water control system from Hydronix. It is used in the concrete industry for controlling the mix cycle to automatically provide the correct addition of water in the shortest possible mixing time.
Using the reading from a Hydro-Mix or Hydro-Probe Orbiter sensor installed inside a mixer, the Hydro-Control V (HC05) accurately monitors the moisture levels of the material throughout the mix cycle, in both wet and dry mix stages. Using known recipes, the correct amount of water is then automatically calculated and added to the mix. This ensures that the required moisture target can be easily achieved, batch after batch.
Designed to be simple to operate and install, the Hydro-Control V can be used as a stand alone unit or installed into a control system, in both new and existing concrete plants. It has an easy to read graphical display which provides a wide range of information via a series of menus including mixing cycle status, recipe information, sensor signal trend and system diagnostics.
The unit incorporates a choice of different operating modes and is a multi-language system, making it the most versatile system on the market with different modes of control to suit all applications.
