DP4 - Piggable Valve
Brand: Waukesha Cherry-BurrellPiggable 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.
FeaturesHigh value, Low life cycle costs:
- Pig use enables valuable product recovery
- Pig use decreases downtime related to cleaning, and the costs associated with wastewater and CIP fluid
- Reduced inventory costs with same seal kit used on multiple size ranges such as one kit for 1.5” - 3.0” sizes
- Low air consumption and air supply requirements
- Leak drain with clamp connection for CIP fluid collection
- Long housing ports ease manifold building
Reliable performance:
- Design based on the proven D4SL model
- Long stroke for gentle product handling and low flow resistance
- Balanced design of lower shafts helps to prevent hydraulic blocking and enables flexible flow direction without slamming
- Heavy-duty bolted flange connection provides secure, controlled assembly/disassembly of valve insert
- No compressed air needed for removal and servicing
- Range of control units and bus communication for automated operation
Cleanability:
- Designed to the latest global hygienic standards
- Extensive cleaning of product contact seals via seat lifting of upper and lower shaft
- Cavity spray cleaning as standard
- Radial seal design provides minimal switching leakage
- External flushing of outside area of the lower shaft below the shaft seal
