Non Return Valves (for drainage) 

IPS are the exclusive UK & Ireland partner for KESSEL AG, a German company that have been supplying into the flood mitigation sector for 45+ years, with the Staufix Inline NRV as early as 1970, to Automatic Systems with over pumping of today. In fact the majority of inline NRV’s on the market today, are created using the Staufix as a base, as it’s the only basic backwater protection valve that full complies with the standard EN13564, when it comes to structure, flow resistance, and most importantly pressure testing to 0.5bar on flap and cover.

To many in this sector, KESSEL is the standard, and the key products in the range are:

  • Staufix Basic – Inline NRV – single flap/single flap locking/double flap locking – 4” & 6”
  • Drehfix – Basement/Floor drain – double flap locking – 4”
  • Staufix FKA – Inline automatic NRV – 4”, 6” & 8” – Open when at rest.
