Dry Pipe Valve Accelerator

  • Designed for use with Model DPV-1 dry pipe valves
  • Speeds operation of the dry pipe valve upon loss of air pressure
  • Automatically adjusts to small or slow changes in system pressure but trips upon a rapid and steady drop in pressure
  • Designed to trip when system air pressure drops at a rate exceeding approximately 1 psi/minute (0.07 bar/min)
  • Upon tripping, it transmits system air pressure to the intermediate chamber of the dry pipe valve, which neutralizes the differential pressure holding the valve closed and opens the waterway clapper
  • Rated for use at a maximum water supply pressure of 250 psi (17,2 bar) and a maximum system air (or nitrogen) pressure of 70 psi (4,8 bar)
  • Listings and Approvals: UL, ULC, FM, and LPCB
