DP4 – Piggable Valve

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.

Features & Benefits

High Value, Low Life Cycle Costs

Pig use enables valuable product recovery
Reduces downtime and cleaning costs related to wastewater and CIP fluid
Lower inventory costs with universal seal kits for 1.5”–3.0” size ranges
Low air consumption and minimal air supply requirements
Leak drain with clamp connection for efficient CIP fluid collection
Extended housing ports simplify manifold construction

Reliable Performance

Engineered from the proven D4SL model
Long stroke ensures gentle product handling and low flow resistance
Balanced lower shaft design prevents hydraulic blocking and supports flexible flow direction without slamming
Heavy-duty bolted flange connection allows secure, controlled valve insert assembly/disassembly
No compressed air required for servicing or removal
Available with a range of control units and bus communication for automated operation

Cleanability

Compliant with the latest global hygienic standards
Seat lifting of upper and lower shafts enables thorough cleaning of product contact seals
Standard cavity spray cleaning for internal hygiene
Radial seal design minimizes switching leakage
External flushing of the lower shaft area below the shaft seal
