Laufer Valve

Pig Diverter Shutter Valve

Ideal for hygienic pigging processes

LAUFER pig diverter shutter valves have been designed according to hygienic design guidelines to meet the high demands of process engineering applications. They build upon the same design principle as free flow shutter valves. By virtue of this principle no products remain in the valves during operation.

The prime use of LAUFER pig diverter shutter valves is with sterile pigging systems as they can be disassembled easily and quickly even when welded in place, and additionally, offer high CIP capability.

Features

  • No dead pockets
  • EHEDG-certified CIP/SIP capability (hygienic design)
  • Totally clear passage - no pressure loss
  • No product remainders or sticking of solid particles
  • Designed to be passed with DMV lip pigs
  • Compact design for 90° installation
  • Minimum number of components and wearing parts
  • Can be completely dismantled even when welded in place
  • 3-A 51-01 and FDA compliance
  • CRN
