Flanged wet alarm valve

Connection Ends: BS EN 1092-2:1997
Temperature Range: 0℃- 80℃
Coating: Painting or Fusion Bonded Epoxy Coating in accordance with ANSI/AWWA C550
Statement: The alarm check valve works as a check valve by preventing the reverse flow of water from the system piping to the water supply. The valve is trimmed with a water bypass line, which has an in-line swing check valve. The bypass line allows pressure surges to enter the system and to be trapped above the alarm check valve’s clapper without the clapper lifting and causing false alarms.
