Manufactured from cast brass*, our angle valves are for Trim or Drain applications and are designed to be suitable for all sprinkler systems including high pressure sprinkler systems. The soft seat design utilizes NBR Nancar N70 material for positive sealing to 300 psi. The most common use for the 2” IPS size is as a system drain at the riser. May be used on both alarm valve and shotgun type riser assemblies
