Piggable valves enable you to recover costly products out of product lines. Once the pig is forced through the line, the remaining product film on the inside of the product line can then be removed with much less CIP fluid which lowers the amount of wastewater, cleaning fluids and cleaning time. They are particularly well suited in processing viscous fluids.
Description
Valve System Overview
High Value, Low Life Cycle Costs
- Pig use enables valuable product recovery
- Pig use decreases downtime related to cleaning, and reduces wastewater and CIP fluid costs
- Shared seal kit for 1.5” – 3.0” valve sizes reduces inventory requirements
- Low air consumption and minimal air supply needs
- Clamp connection leak drain supports effective CIP fluid collection
- Extended housing ports simplify manifold construction
Reliable Performance
- Design based on the field-proven D4SL model
- Long stroke enables gentle product handling and low flow resistance
- Balanced lower shaft design prevents hydraulic blockage and allows dual flow direction
- Heavy-duty bolted flange offers secure insert installation and removal
- Insert servicing requires no compressed air
- Compatible with a wide range of control units and bus communication systems
Cleanability Features
- Complies with global hygienic standards
- Upper/lower shaft seat-lift supports comprehensive seal cleaning
- Standard cavity spray cleaning functionality
- Radial seal design minimizes switching-related leakage
- External flushing port for lower shaft cleaning below shaft seal
