The mtv/d* valve drive together with a screw-in fluid body and an easy to fit valve seat make up a dis-pensing valve for metering a range of media from low viscosity fluids through to high viscous or paste-like media. Media feed and dispensing are hermetically isolated from the valve drive.
The main component of the modular valve drive is a piezo ceramic actuator. The movement of the actua-tor is transmitted to a rod which actuates the valve seat and opens or closes the integrated sealing seat to dispense the medium. Parts in contact with medium which become contaminated or worn can be exchanged easily and quickly. The modular valve drive itself is largely maintenance and wear and tear free.
