Question by: Ronnie H on Aug 30, 2025, 3:24 PM
got a D03 stack setup already. is this one the pressure reducing style that drops pressure in P, and it’s piloted from P too?
Answer by: Customer Support on Sep 1, 2025, 8:09 AM
Function-wise, it is a pressure reducing valve set up for pressure reduced in P and piloted from P, in an NFPA-D03 SystemStak format.
Question by: Peggy B on Jun 19, 2025, 9:26 PM
So this thing reduces pressure, but how much can it handle coming in?
Answer by: Customer Support on Jun 21, 2025, 6:49 PM
It's rated for a maximum operating pressure of 4500 PSI.
Question by: Wade P on Aug 30, 2025, 2:02 PM
got a stack valve manifold already, does this one fit the NFPA D03 setup or is it some oddball pattern?
Answer by: Customer Support on Aug 31, 2025, 6:47 PM
It is an NFPA-D03 size SystemStak valve with the standard interface, so it is meant to stack in a D03 arrangement and help cut down on extra hydraulic connections and leak points.
