Sizes: 2″ to 12″
Fire protection butterfly valves in wafer, lugged and grooved types with an integral tamper switch, rated for 300 psi. The ductile iron body is fusion bonded epoxy coated, and HD states the valve gives bubble tight shut-off with little pressure drop.
Sizes: 50 to 300 mm (2” to 12”)
Resilient wedge gate valves for fire protection in OS&Y and non-rising stem (NRS) versions, rated for 21 bar (300 psi). The OS&Y type shows clearly whether it is open or shut, and both are UL Listed and FM Approved.
Post indicators that show the position of a non-rising stem gate valve and let it be operated from outside: the HD-IP vertical post for underground valves, adjustable for bury depth, and the HD-WP wall post for valves behind a wall. Both are UL Listed and FM Approved.
Bourdon tube pressure gauges for fire protection systems in a polished stainless steel case that seals against weather, moisture and dust. HDP-1 has a 90 mm dial and phosphor bronze Bourdon tube, and the range is UL Listed and FM Approved.
Sizes: 50 to 200 NB (2” to 8”)
A pilot operated pressure reducing valve for fire protection that brings a high inlet pressure down to a steady, set outlet pressure under varying flow. It comes in 50 to 200 NB with grooved or flanged ends.
A swing check valve that lets water flow one way only, opening when flow pressure exceeds its cracking pressure and closing promptly when flow stops or reverses, to protect the system from back flow and pressure surges. It is UL Listed and FM Approved.
A divided seat ring, rubber faced clapper alarm check valve for wet pipe sprinkler systems, which sounds electric and/or hydraulic alarms when water flows steadily into the system at the rate of one or more sprinklers.
The European Conformity edition of the AV-1-300 alarm valve in DN65, DN100, DN150 and DN200, supplied with European Conformity valve trim and used with or without the RC-1 retard chamber.
