Efficient protection against rodents

  • Compatible with the standard, the safe distance of the bottom of the casing ensures proper operation and allows for the self-cleaning of the valves
  • The shape of the chromium-nickel stainless steel guard protects the flap and gasket from damage by rodents and the slipping of the seals during sewage flow.
  • Smooth and properly shaped internal surface allows free flow of sewage and makes the accumulation of deposits or the blocking up of the valve impossible
