Test and Drain valve for sprinkler systems combines the functions of test and drain for wet sprinkler systems. This valves have forged brass body with chrome plate brass ball valve and PTFE seats. The valves complies with the requirements of NFPA-13, NFPA- 13R and NFPA-13D. This valves are single handle ball valves with three working positions. They include tamper resistant test orifice and sight glass for the visual control.

Female/female threads. Lever handle in steel Full Port Valve C37700 or C46500 Brass or Nickel plated Working Temperature : -20°C to 110°C Threads: NPT Max. Working Pressure at 20°C with water 42 Bar for ¼” to 2” 28 bar for 2½” to 4”

Designed for both indoor and outdoor use; Equipped with tamper resistant screws to prevent unauthorized entry. Two synchronized switches are enclosed in a durable terminal block. Terminals are easy to read and wire. Built-In mechanical time delay feature; minimizing the risk of false alarms due to pressure surges or air trapped in the system. Offers excellent performance during riser vibrations caused by large in-rushes of water. Designed and built for accuracy and repeatability. Sealed retard mechanism immune to dust and other contaminants Field-replaceable retard mechanism and SPDT switches Rugged, dual SPDT switches enclosed in a durable terminal block 100 percent synchronization activates both alarm panel and local bell Tamper-resistant cover screws

Alarm Valve is a double seated clapper check valve with grooved seat design, which ensures positive water flow for alarm operation and is designed for installation in wet pipe sprinkler system. External bypass prevents false alarm under all supply pressure condition. In the event of variable pressure condition, false alarm is prevented with the provision of retard chamber, thus the design allows for installation under both variable and constant supply pressure condition. Operation of one or more automatic fire sprinklers causes the water to flow into the sprinkler system causing the alarm valve to open, allowing continuous flow of water into the system and transmittal of alarm, both electrical and mechanical.
