SPX FLOW has launched a new range of mix-proof hygienic valves.

The next-generation D4 Series can be used for the reliable separation of dissimilar products, and includes a range of models and standard features to meet different processing needs.

Intended to ensure complete cleaning of product contact surfaces, the valves are designed to reduce operational cost overheads by minimising CIP losses. 

All D4 valves are fully balanced for dependable operation against pressure spikes and flow in any direction.

The assurance of genuine automated processing is enhanced with the option of a unique, state-of-the-art control unit with integrated seat lift detection and no external sensors.

Maintenance is optimised, as no compressed air or lifting tools are required for removal and service. Downward-opening valves, for example, facilitate easy handling through weighing typically 40 per cent less than equivalent models on the market.

Use of the D4 Series further optimises inventory investment, as the same seal kit is used across multiple valve sizes.

The complete D4 range includes the D4 model, which meets the basic needs for reliable product separation and seat lift (SL) or non-seat lift (NSL) cleanability, and the DA4 ultra-hygienic model for critical applications requiring enhanced cleanability of all product contact surfaces.
