Engineering FAQ
Q1: Can APC deluge valves be installed in vertical positions?
Yes, both horizontal and vertical installation are supported. For vertical mounting, the solenoid must be positioned to ensure the core remains strictly vertical to prevent mechanical friction or jamming.
Q2: What is the recommended maintenance schedule per NFPA?
Alarm tests monthly; manual and remote switch function tests quarterly. Always disable the valve before maintenance.
Q3: What causes "seal failure" in the straight-through cone diaphragm?
Sediment or debris buildup. Perform a thorough pipe rinse before installation until water flows clear.
Q4: How do I achieve Hydrostatic Equilibrium during reset?
Depress the manual reset button until the upper and lower pressure gauges show identical readings.
Q5: What is the primary function of the integrated solenoid?
It acts as the electric interface for the FACP to release diaphragm chamber pressure and trigger the valve.
