Product Q&A

Q:When ZSFZ valves connect to outdoor fire hydrants, how to balance pressure between the indoor wet system and hydrant flow to avoid underperformance?

Install a pressure reducing valve (PRV) on the hydrant branch, set to 1.2x the ZSFZ valve's operating pressure (e.g., 1.6MPa if ZSFZ uses 1.3MPa). Add a check valve between the systems to prevent hydrant flow from siphoning water away from the indoor loop.

Q:If a building is vacant for 2+ years (e.g., unoccupied construction projects), what steps are needed to safely restart the ZSFZ system?

1. Flush the entire pipe network with 50ppm chlorine solution to remove stagnant water biofilm. 2. Disassemble the retard chamber, clean its orifices with a soft brush, and replace the diaphragm (even if undamaged, rubber degrades over time). 3. Perform a 30-minute pressure test (1.5x working pressure) to check for leaks before reactivating alarms.

Q:When replacing old ZSFZ valves, how to ensure disposal meets EU RoHS or US EPA standards for hazardous materials?

Dismantle the valve to separate materials: recycle 316L stainless steel components as scrap metal; incinerate rubber seals (certified for low VOC emissions); neutralize any residual hydraulic fluid (use absorbent pads compliant with EPA 40 CFR Part 261) before disposal. For leaded brass parts (if present in older models), send to a licensed hazardous waste recycler.
