The MF4 valve is air operated and failsafe to close, and is capable of flow rates from 4 to 4000g/s.
The fast response time, from fully open to fully closed, ensures that target dispenses of products are achieved rapidly.
Multi-stage flows in the above ranges allow a dispense system to to weigh quantities ranging from hundreds of kilos to tenths of grams, all from a single valve.
Within a typical dispense system the dispense valves are frequently required to handle products which need recirculating to maintain the integrity of the materials, so a recirculation facility is a standard feature of the Ozark MF4 valve.
When dispensing products into small diameter containers the flow from a dispense valve must be spray- and splash-free.
This is particularly important when handling low viscosity materials.
In the Ozark MF4 valve, the liquid exit is designed to give a clean cutoff, which results in no dripping or build-up of the product.
In addition, the valve is suitable for both pumped and gravity fed operations, and will handle liquid media pressure up to and including 8bar.
The valve is capable of handling viscosities ranging from water-like materials to those with a mayonnaise-like consistency.
Control of the MF4 valve for systems designed and supplied by Ozark Systems can be by PC or PLC, dependent on the application and the customer's requirements.
Overall system sizes range from three-valve/three-component systems to 48-valve systems for combined colour and chemical applications.
