LIAG® Free Flow Shutter Valves

LIAG® Free Flow Shutter Valves

Ideal for pasty media and hygienic pigging processes

LIAG®  free flow 3A shutter valves have been designed according to hygienic guidelines to meet the high demands of process engineering applications. LIAG®  valves are particularly suited for viscous/pasty products and fluids containing solid particles on account of a totally clear passage, as well as, easy and thorough cleaning in place. LIAG® 3A valves have also passed the testing requirements for CIP/SIP capability.

Features

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