Sprinkler Glass Bulb Type

NDC automatic sprinklers NT25 and NT26 model series incorporate decorative glass bulbs that operate at specific temperatures. These sprinklers are designed to discharge water in an umbrella-shaped spray pattern for use in various commercial application.

Alarm Check Valves

NDC NWAV-1 Alarm Check Valves are swing type waterflow alarm check valves intended for use in automatic wet-pipe fire sprinkler system. They activate the fire alarm via the pressure-actuated alarm switch when the water that is flowing into the system is equivalent to the discharge from one or more sprinklers. With the clapper having rubber facing that sits well with the seat ring, they also prevent water backflow when the water supply is stopped. They can also be fitted with a separately ordered retard chamber for installations subject to variable pressures. The retard chamber provides suitable time delay in order to eliminate potential false alarms due to surges or fluctuating water supply pressures. These Alarm Check Valves are intended to be installed in vertical orientation only.

Weight (Flanged ends)	13.1kg	14.7kg	16.7kg	28.2kg

Deluge Valve

The NDV-1 Deluge Valve features a unique pressure-operated tubular diaphragm configured axially inline with the water flow. The tubular diaphragm is a single-piece resilient and durable rubber part that has been shaped to create a control chamber with the valve body. Inlet water pressure supplied into the chamber pushes the diaphragm against the centrally-located seat, creating an airtight seal that prevents water flow.
