The flush valve is suitable for connection to DN 12-80 manifold or riser pipes.
  • Page 13 Product information Water exchange actuation The following additional or customer-provided components can actuate water exchange (flushing): Timer Building control system (BCS) Furthermore, the flush valve flushes all valves for 10 seconds every 72 hours (time-delayed cycle: 1.5 s open, 1.5 s closed) to prevent blocking of valves and stagnation of the water within the valve.
  • Page 14 Product information The flush valve comprises a siphon / odour trap. No addi- tional siphon is required outside of the flush valve. NOTICE! The dimension of the wastewater conduits must comply with the specifications of DIN 1986-100. Flowthrough monitoring During a water exchange, a flow switch checks whether water is dis- charged in the proper manner.
