FOR CATEGORY 1 SYSTEMS
DMR DN32/1 1/4″ Fire Sprinkler Domestic Valve Set Riser Manifold complete with SIKA® VKF flow switch alarm for Category 1 Domestic Fire Sprinkler systems.
For larger piped systems the Patent pending RiserTeQ™ DMR Fire Sprinkler Valve Set is focused on saving space with just a 225mm overall usable length. This is the shortest Fire Sprinkler Domestic Valve Set on the market for DN32 pipework. Compatible with CPVC or Malleable Iron piping Fire Sprinkler Category 1 systems.
The manifold has been designed for use with the SIKA VKF fire sprinkler flow switch which is approved with LPCB, CE and UKCA to EN12259-5 making it suitable for EN 16925:2018 installations and also BS9251:2021 from BSI.
The Fire Sprinkler valve set DMR32 system is specifically designed for tight spaces found in the Domestic category 1 fire sprinkler application. These locations can be in cupboards or under sinks in larger domestic houses, combined with the SIKA Fire Sprinkler flow switch.
The patent pending technology is the result of extensive research and development coupled with high quality components and finish. The DMR32 Fire Sprinkler valve set riser manifold is a major step into designing products suitable for Residential and Domestic fire sprinkler systems.
RiserTeQ is committed to designing and supplying high quality Fire Sprinkler Domestic valve sets which is also economical for the full service life of the product.
