Double seal valve D

Double seal valve D

Separation of hostile substances such as CIP, water or gases in the hygienic zone

With hygienic double seal valves, Evoguard offers an economic alternative to double seat valves.

  • Three-piece threaded valve disk with identical seal rings
  • Two seals between the pipes in the closed position
  • Hygienic sealing directly at the product chamber, without dead space
  • Leakage chamber with two rinsing valves for leakage indication
  • Cleaning of the leakage chamber by means of tangential inflow of the flush medium
  • Design of the shaft seal:
    • Wiping function protects against contamination ingress
    • Geometry protects the seal against being torn out
  • Rotational decoupling between valve shaft and actuator for a torsion-free lift motion of the valve disk
